# Release Notes

## 3.2.1
### Changes
- Podman now allows corrupt images (e.g. from restarting the system during an image pull) to be replaced by a `podman pull` of the same image (instead of requiring they be removed first, then re-pulled).

### Bugfixes
- Fixed a bug where Podman would fail to start containers if a Seccomp profile was not available at `/usr/share/containers/seccomp.json` ([#10556](https://github.com/containers/podman/issues/10556)).
- Fixed a bug where the `podman machine start` command failed on OS X machines with the AMD64 architecture and certain QEMU versions ([#10555](https://github.com/containers/podman/issues/10555)).
- Fixed a bug where Podman would always use the slow path for joining the rootless user namespace.
- Fixed a bug where the `podman stats` command would fail on Cgroups v1 systems when run on a container running systemd ([#10602](https://github.com/containers/podman/issues/10602)).
- Fixed a bug where pre-checkpoint support for `podman container checkpoint` did not function correctly.
- Fixed a bug where the remote Podman client's `podman build` command did not properly handle the `-f` option ([#9871](https://github.com/containers/podman/issues/9871)).
- Fixed a bug where the remote Podman client's `podman run` command would sometimes not resize the container's terminal before execution began ([#9859](https://github.com/containers/podman/issues/9859)).
- Fixed a bug where the `--filter` option to the `podman image prune` command was nonfunctional.
- Fixed a bug where the `podman logs -f` command would exit before all output for a container was printed when the `k8s-file` log driver was in use ([#10596](https://github.com/containers/podman/issues/10596)).
- Fixed a bug where Podman would not correctly detect that systemd-resolved was in use on the host and adjust DNS servers in the container appropriately under some circumstances ([#10570](https://github.com/containers/podman/issues/10570)).
- Fixed a bug where the `podman network connect` and `podman network disconnect` commands acted improperly when containers were in the Created state, marking the changes as done but not actually performing them.

### API
- Fixed a bug where the Compat and Libpod Prune endpoints for Networks returned null, instead of an empty array, when nothing was pruned.
- Fixed a bug where the Create API for Images would continue to pull images even if a client closed the connection mid-pull ([#7558](https://github.com/containers/podman/issues/7558)).
- Fixed a bug where the Events API did not include some information (including labels) when sending events.
- Fixed a bug where the Events API would, when streaming was not requested, send at most one event ([#10529](https://github.com/containers/podman/issues/10529)).

### Misc
- Updated the containers/common library to v0.38.9

## 3.2.0
### Features
- Docker Compose is now supported with rootless Podman ([#9169](https://github.com/containers/podman/issues/9169)).
- The `podman network connect`, `podman network disconnect`, and `podman network reload` commands have been enabled for rootless Podman.
- An experimental new set of commands, `podman machine`, was added to assist in managing virtual machines containing a Podman server. These are intended for easing the use of Podman on OS X by handling the creation of a Linux VM for running Podman.
- The `podman generate kube` command can now be run on Podman named volumes (generating `PersistentVolumeClaim` YAML), in addition to pods and containers.
- The `podman play kube` command now supports two new options, `--ip` and `--mac`, to set static IPs and MAC addresses for created pods ([#8442](https://github.com/containers/podman/issues/8442) and [#9731](https://github.com/containers/podman/issues/9731)).
- The `podman play kube` command's support for `PersistentVolumeClaim` YAML has been greatly improved.
- The `podman generate kube` command now preserves the label used by `podman auto-update` to identify containers to update as a Kubernetes annotation, and the `podman play kube` command will convert this annotation back into a label. This allows `podman auto-update` to be used with containers created by `podman play kube`.
- The `podman play kube` command now supports Kubernetes `secretRef` YAML (using the secrets support from `podman secret`) for environment variables.
- Secrets can now be added to containers as environment variables using the `type=env` option to the `--secret` flag to `podman create` and `podman run`.
- The `podman start` command now supports the `--all` option, allowing all containers to be started simultaneously with a single command. The `--filter` option has also been added to filter which containers to start when `--all` is used.
- Filtering containers with the `--filter` option to `podman ps` and `podman start` now supports a new filter, `restart-policy`, to filter containers based on their restart policy.
- The `--group-add` option to rootless `podman run` and `podman create` now accepts a new value, `keep-groups`, which instructs Podman to retain the supplemental groups of the user running Podman in the created container. This is only supported with the `crun` OCI runtime.
- The `podman run` and `podman create` commands now support a new option, `--timeout`. This sets a maximum time the container is allowed to run, after which it is killed ([#6412](https://github.com/containers/podman/issues/6412)).
- The `podman run` and `podman create` commands now support a new option, `--pidfile`. This will create a file when the container is started containing the PID of the first process in the container.
- The `podman run` and `podman create` commands now support a new option, `--requires`. The `--requires` option adds dependency containers - containers that must be running before the current container. Commands like `podman start` will automatically start the requirements of a container before starting the container itself.
- Auto-updating containers can now be done with locally-built images, not just images hosted on a registry, by creating containers with the `io.containers.autoupdate` label set to `local`.
- Podman now supports the [Container Device Interface](https://github.com/container-orchestrated-devices/container-device-interface) (CDI) standard.
- Podman now adds an entry to `/etc/hosts`, `host.containers.internal`, pointing to the current gateway (which, for root containers, is usually a bridge interface on the host system) ([#5651](https://github.com/containers/podman/issues/5651)).
- The `podman ps`, `podman pod ps`, `podman network list`, `podman secret list`, and `podman volume list` commands now support a `--noheading` option, which will cause Podman to omit the heading line including column names.
- The `podman unshare` command now supports a new flag, `--rootless-cni`, to join the rootless network namespace. This allows commands to be run in the same network environment as rootless containers with CNI networking.
- The `--security-opt unmask=` option to `podman run` and `podman create` now supports glob operations to unmask a group of paths at once (e.g. `podman run --security-opt unmask=/proc/* ...` will unmask all paths in `/proc` in the container).
- The `podman network prune` command now supports a `--filter` option to filter which networks will be pruned.

### Changes
- The change in Podman 3.1.2 where the `:z` and `:Z` mount options for volumes were ignored for privileged containers has been reverted after discussion in [#10209](https://github.com/containers/podman/issues/10209).
- Podman's rootless CNI functionality no longer requires a sidecar container! The removal of the requirement for the `rootless-cni-infra` container means that rootless CNI is now usable on all architectures, not just AMD64, and no longer requires pulling an image ([#8709](https://github.com/containers/podman/issues/8709)).
- The Image handling code used by Podman has seen a major rewrite to improve code sharing with our other projects, Buildah and CRI-O. This should result in fewer bugs and performance gains in the long term. Work on this is still ongoing.
- The `podman auto-update` command now prunes previous versions of images after updating if they are unused, to prevent disk exhaustion after repeated updates ([#10190](https://github.com/containers/podman/issues/10190)).
- The `podman play kube` now treats environment variables configured as references to a `ConfigMap` as mandatory unless the `optional` parameter was set; this better matches the behavior of Kubernetes.
- Podman now supports the `--context=default` flag from Docker as a no-op for compatibility purposes.
- When Podman is run as root, but without `CAP_SYS_ADMIN` being available, it will run in a user namespace using the same code as rootless Podman (instead of failing outright).
- The `podman info` command now includes the path of the Seccomp profile Podman is using, available cgroup controllers, and whether Podman is connected to a remote service or running containers locally.
- Containers created with the `--rm` option now automatically use the `volatile` storage flag when available for their root filesystems, causing them not to write changes to disk as often as they will be removed at completion anyways. This should result in improved performance.
- The `podman generate systemd --new` command will now include environment variables referenced by the container in generated unit files if the value would be looked up from the system environment.
- Podman now requires that Conmon v2.0.24 be available.

### Bugfixes
- Fixed a bug where the remote Podman client's `podman build` command did not support the `--arch`, `--platform`, and `--os`, options.
- Fixed a bug where the remote Podman client's `podman build` command ignored the `--rm=false` option ([#9869](https://github.com/containers/podman/issues/9869)).
- Fixed a bug where the remote Podman client's `podman build --iidfile` command could include extra output (in addition to just the image ID) in the image ID file written ([#10233](https://github.com/containers/podman/issues/10233)).
- Fixed a bug where the remote Podman client's `podman build` command did not preserve hardlinks when moving files into the container via `COPY` instructions ([#9893](https://github.com/containers/podman/issues/9893)).
- Fixed a bug where the `podman generate systemd --new` command could generate extra `--iidfile` arguments if the container was already created with one.
- Fixed a bug where the `podman generate systemd --new` command would generate unit files that did not include `RequiresMountsFor` lines ([#10493](https://github.com/containers/podman/issues/10493)).
- Fixed a bug where the `podman generate kube` command produced incorrect YAML for containers which bind-mounted both `/` and `/root` from the host system into the container ([#9764](https://github.com/containers/podman/issues/9764)).
- Fixed a bug where pods created by `podman play kube` from YAML that specified `ShareProcessNamespace` would only share the PID namespace (and not also the UTS, Network, and IPC namespaces) ([#9128](https://github.com/containers/podman/issues/9128)).
- Fixed a bug where the `podman network reload` command could generate spurious error messages when `iptables-nft` was in use.
- Fixed a bug where rootless Podman could fail to attach to containers when the user running Podman had a large UID.
- Fixed a bug where the `podman ps` command could fail with a `no such container` error due to a race condition with container removal ([#10120](https://github.com/containers/podman/issues/10120)).
- Fixed a bug where containers using the `slirp4netns` network mode and setting a custom `slirp4netns` subnet while using the `rootlesskit` port forwarder would not be able to forward ports ([#9828](https://github.com/containers/podman/issues/9828)).
- Fixed a bug where the `--filter ancestor=` option to `podman ps` did not require an exact match of the image name/ID to include a container in its results.
- Fixed a bug where the `--filter until=` option to `podman image prune` would prune images created after the specified time (instead of before).
- Fixed a bug where setting a custom Seccomp profile via the `seccomp_profile` option in `containers.conf` had no effect, and the default profile was used instead.
- Fixed a bug where the `--cgroup-parent` option to `podman create` and `podman run` was ignored in rootless Podman on cgroups v2 systems with the `cgroupfs` cgroup manager ([#10173](https://github.com/containers/podman/issues/10173)).
- Fixed a bug where the `IMAGE` and `NAME` variables in `podman container runlabel` were not being correctly substituted ([#10192](https://github.com/containers/podman/issues/10192)).
- Fixed a bug where Podman could freeze when creating containers with a specific combination of volumes and working directory ([#10216](https://github.com/containers/podman/issues/10216)).
- Fixed a bug where rootless Podman containers restarted by restart policy (e.g. containers created with `--restart=always`) would lose networking after being restarted ([#8047](https://github.com/containers/podman/issues/8047)).
- Fixed a bug where the `podman cp` command could not copy files into containers created with the `--pid=host` flag ([#9985](https://github.com/containers/podman/issues/9985)).
- Fixed a bug where filters to the `podman events` command could not be specified twice (if a filter is specified more than once, it will match if any of the given values match - logical or) ([#10507](https://github.com/containers/podman/issues/10507)).
- Fixed a bug where Podman would include IPv6 nameservers in `resolv.conf` in containers without IPv6 connectivity ([#10158](https://github.com/containers/podman/issues/10158)).
- Fixed a bug where containers could not be created with static IP addresses when connecting to a network using the `macvlan` driver ([#10283](https://github.com/containers/podman/issues/10283)).

### API
- Fixed a bug where the Compat Create endpoint for Containers did not allow advanced network options to be set ([#10110](https://github.com/containers/podman/issues/10110)).
- Fixed a bug where the Compat Create endpoint for Containers ignored static IP information provided in the `IPAMConfig` block ([#10245](https://github.com/containers/podman/issues/10245)).
- Fixed a bug where the Compat Inspect endpoint for Containers returned null (instead of an empty list) for Networks when the container was not joined to a CNI network ([#9837](https://github.com/containers/podman/issues/9837)).
- Fixed a bug where the Compat Wait endpoint for Containers could miss containers exiting if they were immediately restarted.
- Fixed a bug where the Compat Create endpoint for Volumes required that the user provide a name for the new volume ([#9803](https://github.com/containers/podman/issues/9803)).
- Fixed a bug where the Libpod Info handler would sometimes not return the correct path to the Podman API socket.
- Fixed a bug where the Compat Events handler used the wrong name for container exited events (`died` instead of `die`) ([#10168](https://github.com/containers/podman/issues/10168)).
- Fixed a bug where the Compat Push endpoint for Images could leak goroutines if the remote end closed the connection prematurely.

### Misc

- Updated the containers/common library to v0.38.5
- Updated the containers/storage library to v1.31.3

## 3.1.2
### Bugfixes
- The Compat Export endpoint for Images now supports exporting multiple images at the same time to a single archive.
- Fixed a bug where images with empty layers were stored incorrectly, causing them to be unable to be pushed or saved.
- Fixed a bug where the `podman rmi` command could fail to remove corrupt images from storage.
- Fixed a bug where the remote Podman client's `podman save` command did not support the `oci-dir` and `docker-dir` formats ([#9742](https://github.com/containers/podman/issues/9742)).
- Fixed a bug where volume mounts from `podman play kube` created with a trailing `/` in the container path were were not properly superceding named volumes from the image ([#9618](https://github.com/containers/podman/issues/9618)).

### Misc
- Updated the containers/image library to v5.11.1

## 3.1.1
### Changes
- Podman now recognizes `trace` as a valid argument to the `--log-level` command. Trace logging is now the most verbose level of logging available.
- The `:z` and `:Z` options for volume mounts are now ignored when the container is privileged or is run with SELinux isolation disabled (`--security-opt label=disable`). This matches better matches Docker's behavior in this case.

### Bugfixes
- Fixed a bug where pruning images with the `podman image prune` or `podman system prune` commands could cause Podman to panic.
- Fixed a bug where the `podman save` command did not properly error when the `--compress` flag was used with incompatible format types.
- Fixed a bug where the `--security-opt` and `--ulimit` options to the remote Podman client's `podman build` command were nonfunctional.

- Fixed a bug where rootless Podman could fail to launch containers on cgroups v2 systems when the `cgroupfs` cgroup manager was in use.
- Fixed a bug where the `podman stats` command could error when statistics tracked exceeded the maximum size of a 32-bit signed integer ([#9979](https://github.com/containers/podman/issues/9979)).
- Fixed a bug where rootless Podman containers run with `--userns=keepid` (without a `--user` flag in addition) would grant exec sessions run in them too many capabilities ([#9919](https://github.com/containers/podman/issues/9919)).
- Fixed a bug where the `--authfile` option to `podman build` did not validate that the path given existed ([#9572](https://github.com/containers/podman/issues/9572)).

- Fixed a bug where the Libpod DF endpoint could, in error cases, append an extra null to the JSON response, causing decode errors.
- Fixed a bug where the Libpod and Compat Top endpoint for Containers would return process names that included extra whitespace.
- Fixed a bug where the Compat Prune endpoint for Containers accepted too many types of filter.

### Misc
- Updated Buildah to v1.20.1
- Updated the containers/storage library to v1.29.0
- Updated the containers/image library to v5.11.0

## 3.1.0
### Features
- A set of new commands has been added to manage secrets! The `podman secret create`, `podman secret inspect`, `podman secret ls` and `podman secret rm` commands have been added to handle secrets, along with the `--secret` option to `podman run` and `podman create` to add secrets to containers. The initial driver for secrets does not support encryption - this will be added in a future release.
- A new command to prune networks, `podman network prune`, has been added ([#8673](https://github.com/containers/podman/issues/8673)).
- The `-v` option to `podman run` and `podman create` now supports a new volume option, `:U`, to chown the volume's source directory on the host to match the UID and GID of the container and prevent permissions issues ([#7778](https://github.com/containers/podman/issues/7778)).
- Three new commands, `podman network exists`, `podman volume exists`, and `podman manifest exists`, have been added to check for the existence of networks, volumes, and manifest lists.
- The `podman cp` command can now copy files into directories mounted as `tmpfs` in a running container.
- The `podman volume prune` command will now list volumes that will be pruned when prompting the user whether to continue and perform the prune ([#8913](https://github.com/containers/podman/issues/8913)).
- The Podman remote client's `podman build` command now supports the `--disable-compression`, `--excludes`, and `--jobs` options.
- The Podman remote client's `podman push` command now supports the `--format` option.
- The Podman remote client's `podman rm` command now supports the `--all` and `--ignore` options.
- The Podman remote client's `podman search` command now supports the `--no-trunc` and `--list-tags` options.
- The `podman play kube` command can now read in Kubernetes YAML from `STDIN` when `-` is specified as file name (`podman play kube -`), allowing input to be piped into the command for scripting ([#8996](https://github.com/containers/podman/issues/8996)).
- The `podman generate systemd` command now supports a `--no-header` option, which disables creation of the header comment automatically added by Podman to generated unit files.
- The `podman generate kube` command can now generate `PersistentVolumeClaim` YAML for Podman named volumes ([#5788](https://github.com/containers/podman/issues/5788)).
- The `podman generate kube` command can now generate YAML files containing multiple resources (pods or deployments) ([#9129](https://github.com/containers/podman/issues/9129)).

### Security
- This release resolves CVE-2021-20291, a deadlock vulnerability in the storage library caused by pulling a specially-crafted container image.

### Changes
- The Podman remote client's `podman build` command no longer allows the `-v` flag to be used. Volumes are not yet supported with remote Podman when the client and service are on different machines.
- The `podman kill` and `podman stop` commands now print the name given by the user for each container, instead of the full ID.
- When the `--security-opt unmask=ALL` or `--security-opt unmask=/sys/fs/cgroup` options to `podman create` or `podman run` are given, Podman will mount cgroups into the container as read-write, instead of read-only ([#8441](https://github.com/containers/podman/issues/8441)).
- The `podman rmi` command has been changed to better handle cases where an image is incomplete or corrupted, which can be caused by interrupted image pulls.
- The `podman rename` command has been improved to be more atomic, eliminating many race conditions that could potentially render a renamed container unusable.
- Detection of which OCI runtimes run using virtual machines and thus require custom SELinux labelling has been improved ([#9582](https://github.com/containers/podman/issues/9582)).
- The hidden `--trace` option to `podman` has been turned into a no-op. It was used in very early versions for performance tracing, but has not been supported for some time.
- The `podman generate systemd` command now generates `RequiresMountsFor` lines to ensure necessary storage directories are mounted before systemd starts Podman.
- Podman will now emit a warning when `--tty` and `--interactive` are both passed, but `STDIN` is not a TTY. This will be made into an error in the next major Podman release some time next year.

### Bugfixes
- Fixed a bug where rootless Podman containers joined to CNI networks could not receive traffic from forwarded ports ([#9065](https://github.com/containers/podman/issues/9065)).
- Fixed a bug where `podman network create` with the `--macvlan` flag did not honor the `--gateway`, `--subnet`, and `--opt` options ([#9167](https://github.com/containers/podman/issues/9167)).
- Fixed a bug where the `podman generate kube` command generated invalid YAML for privileged containers ([#8897](https://github.com/containers/podman/issues/8897)).
- Fixed a bug where the `podman generate kube` command could not be used with containers that were not running.
- Fixed a bug where the `podman generate systemd` command could duplicate some parameters to Podman in generated unit files ([#9776](https://github.com/containers/podman/issues/9776)).
- Fixed a bug where Podman did not add annotations specified in `containers.conf` to containers.
- Foxed a bug where Podman did not respect the `no_hosts` default in `containers.conf` when creating containers.
- Fixed a bug where the `--tail=0`, `--since`, and `--follow` options to the `podman logs` command did not function properly when using the `journald` log backend.
- Fixed a bug where specifying more than one container to `podman logs` when the `journald` log backend was in use did not function correctly.
- Fixed a bug where the `podman run` and `podman create` commands would panic if a memory limit was set, but the swap limit was set to unlimited ([#9429](https://github.com/containers/podman/issues/9429)).
- Fixed a bug where the `--network` option to `podman run`, `podman create`, and `podman pod create` would error if the user attempted to specify CNI networks by ID, instead of name ([#9451](https://github.com/containers/podman/issues/9451)).
- Fixed a bug where Podman's cgroup handling for cgroups v1 systems did not properly handle cases where a cgroup existed on some, but not all, controllers, resulting in errors from the `podman stats` command ([#9252](https://github.com/containers/podman/issues/9252)).
- Fixed a bug where the `podman cp` did not properly handle cases where `/dev/stdout` was specified as the destination (it was treated identically to `-`) ([#9362](https://github.com/containers/podman/issues/9362)).
- Fixed a bug where the `podman cp` command would create files with incorrect ownership ([#9526](https://github.com/containers/podman/issues/9626)).
- Fixed a bug where the `podman cp` command did not properly handle cases where the destination directory did not exist.
- Fixed a bug where the `podman cp` command did not properly evaluate symlinks when copying out of containers.
- Fixed a bug where the `podman rm -fa` command would error when attempting to remove containers created with `--rm` ([#9479](https://github.com/containers/podman/issues/9479)).
- Fixed a bug where the ordering of capabilities was nondeterministic in the `CapDrop` field of the output of `podman inspect` on a container ([#9490](https://github.com/containers/podman/issues/9490)).
- Fixed a bug where the `podman network connect` command could be used with containers that were not initially connected to a CNI bridge network (e.g. containers created with `--net=host`) ([#9496](https://github.com/containers/podman/issues/9496)).
- Fixed a bug where DNS search domains required by the `dnsname` CNI plugin were not being added to container's `resolv.conf` under some circumstances.
- Fixed a bug where the `--ignorefile` option to `podman build` was nonfunctional ([#9570](https://github.com/containers/podman/issues/9570)).
- Fixed a bug where the `--timestamp` option to `podman build` was nonfunctional ([#9569](https://github.com/containers/podman/issues/9569)).
- Fixed a bug where the `--iidfile` option to `podman build` could cause Podman to panic if an error occurred during the build.
- Fixed a bug where the `--dns-search` option to `podman build` was nonfunctional ([#9574](https://github.com/containers/podman/issues/9574)).
- Fixed a bug where the `--pull-never` option to `podman build` was nonfunctional ([#9573](https://github.com/containers/podman/issues/9573)).
- Fixed a bug where the `--build-arg` option to `podman build` would, when given a key but not a value, error (instead of attempting to look up the key as an environment variable) ([#9571](https://github.com/containers/podman/issues/9571)).
- Fixed a bug where the `--isolation` option to `podman build` in the remote Podman client was nonfunctional.
- Fixed a bug where the `podman network disconnect` command could cause errors when the container that had a network removed was stopped and its network was cleaned up ([#9602](https://github.com/containers/podman/issues/9602)).
- Fixed a bug where the `podman network rm` command did not properly check what networks a container was present in, resulting in unexpected behavior if `podman network connect` or `podman network disconnect` had been used with the network ([#9632](https://github.com/containers/podman/issues/9632)).

- Fixed a bug where Podman would treat the `--entrypoint=[""]` option to `podman run` and `podman create` as a literal empty string in the entrypoint, when instead it should have been ignored ([#9377](https://github.com/containers/podman/issues/9377)).
- Fixed a bug where Podman would set the `HOME` environment variable to `""` when the container ran as a user without an assigned home directory ([#9378](https://github.com/containers/podman/issues/9378)).
- Fixed a bug where specifying a pod infra image that had no tags (by using its ID) would cause `podman pod create` to panic ([#9374](https://github.com/containers/podman/issues/9374)).

## 3.0.0
### Features
- Podman now features initial support for Docker Compose.
- Added the `podman rename` command, which allows containers to be renamed after they are created ([#1925](https://github.com/containers/podman/issues/1925)).
- The Podman remote client now supports the `podman copy` command.
- A new command, `podman network reload`, has been added. This command will re-configure the network of all running containers, and can be used to recreate firewall rules lost when the system firewall was reloaded (e.g. via `firewall-cmd --reload`).
- Podman networks now have IDs. They can be seen in `podman network ls` and can be used when removing and inspecting networks. Existing networks receive IDs automatically.
- Podman networks now also support labels. They can be added via the `--label` option to `network create`, and `podman network ls` can filter labels based on them.
- The `podman network create` command now supports setting bridge MTU and VLAN through the `--opt` option ([#8454](https://github.com/containers/podman/issues/8454)).
- The `podman container checkpoint` and `podman container restore` commands can now checkpoint and restore containers that include volumes.
- The `podman container checkpoint` command now supports the `--with-previous` and `--pre-checkpoint` options, and the `podman container restore` command now support the `--import-previous` option. These add support for two-step checkpointing with lowered dump times.
- The `podman push` command can now push manifest lists. Podman will first attempt to push as an image, then fall back to pushing as a manifest list if that fails.
- The `podman generate kube` command can now be run on multiple containers at once, and will generate a single pod containing all of them.
- The `podman generate kube` and `podman play kube` commands now support Kubernetes DNS configuration, and will preserve custom DNS configuration when exporting or importing YAML ([#9132](https://github.com/containers/podman/issues/9132)).
- The `podman generate kube` command now properly supports generating YAML for containers and pods creating using host networking (`--net=host`) ([#9077](https://github.com/containers/podman/issues/9077)).
- The `podman kill` command now supports a `--cidfile` option to kill containers given a file containing the container's ID ([#8443](https://github.com/containers/podman/issues/8443)).
- The `podman pod create` command now supports the `--net=none` option ([#9165](https://github.com/containers/podman/issues/9165)).
- The `podman volume create` command can now specify volume UID and GID as options with the `UID` and `GID` fields passed to the the `--opt` option.
- Initial support has been added for Docker Volume Plugins. Podman can now define available plugins in `containers.conf` and use them to create volumes with `podman volume create --driver`.
- The `podman run` and `podman create` commands now support a new option, `--platform`, to specify the platform of the image to be used when creating the container.
- The `--security-opt` option to `podman run` and `podman create` now supports the `systempaths=unconfined` option to unrestrict access to all paths in the container, as well as `mask` and `unmask` options to allow more granular restriction of container paths.
- The `podman stats --format` command now supports a new format specified, `MemUsageBytes`, which prints the raw bytes of memory consumed by a container without human-readable formatting [#8945](https://github.com/containers/podman/issues/8945).
- The `podman ps` command can now filter containers based on what pod they are joined to via the `pod` filter ([#8512](https://github.com/containers/podman/issues/8512)).
- The `podman pod ps` command can now filter pods based on what networks they are joined to via the `network` filter.
- The `podman pod ps` command can now print information on what networks a pod is joined to via the `.Networks` specifier to the `--format` option.
- The `podman system prune` command now supports filtering what containers, pods, images, and volumes will be pruned.
- The `podman volume prune` commands now supports filtering what volumes will be pruned.
- The `podman system prune` command now includes information on space reclaimed ([#8658](https://github.com/containers/podman/issues/8658)).
- The `podman info` command will now properly print information about packages in use on Gentoo and Arch systems.
- The `containers.conf` file now contains an option for disabling creation of a new kernel keyring on container creation ([#8384](https://github.com/containers/podman/issues/8384)).
- The `podman image sign` command can now sign multi-arch images by producing a signature for each image in a given manifest list.
- The `podman image sign` command, when run as rootless, now supports per-user registry configuration files in `$HOME/.config/containers/registries.d`.
- Configuration options for `slirp4netns` can now be set system-wide via the `NetworkCmdOptions` configuration option in `containers.conf`.
- The MTU of `slirp4netns` can now be configured via the `mtu=` network command option (e.g. `podman run --net slirp4netns:mtu=9000`).

### Security
- A fix for CVE-2021-20199 is included. Podman between v1.8.0 and v2.2.1 used `127.0.0.1` as the source address for all traffic forwarded into rootless containers by a forwarded port; this has been changed to address the issue.

### Changes
- Shortname aliasing support has now been turned on by default. All Podman commands that must pull an image will, if a TTY is available, prompt the user about what image to pull.
- The `podman load` command no longer accepts a `NAME[:TAG]` argument. The presence of this argument broke CLI compatibility with Docker by making `docker load` commands unusable with Podman ([#7387](https://github.com/containers/podman/issues/7387)).
- The Go bindings for the HTTP API have been rewritten with a focus on limiting dependency footprint and improving extensibility. Read more [here](https://github.com/containers/podman/blob/v3.0/pkg/bindings/README.md).
- The legacy Varlink API has been completely removed from Podman.
- The default log level for Podman has been changed from Error to Warn.
- The `podman network create` command can now create `macvlan` networks using the `--driver macvlan` option for Docker compatibility. The existing `--macvlan` flag has been deprecated and will be removed in Podman 4.0 some time next year.
- The `podman inspect` command has had the `LogPath` and `LogTag` fields moved into the `LogConfig` structure (from the root of the Inspect structure). The maximum size of the log file is also included.
- The `podman generate systemd` command no longer generates unit files using the deprecated `KillMode=none` option ([#8615](https://github.com/containers/podman/issues/8615)).
- The `podman stop` command now releases the container lock while waiting for it to stop - as such, commands like `podman ps` will no longer block until `podman stop` completes ([#8501](https://github.com/containers/podman/issues/8501)).
- Networks created with `podman network create --internal` no longer use the `dnsname` plugin. This configuration never functioned as expected.
- Error messages for the remote Podman client have been improved when it cannot connect to a Podman service.
- Error messages for `podman run` when an invalid SELinux is specified have been improved.
- Rootless Podman features improved support for containers with a single user mapped into the rootless user namespace.
- Pod infra containers now respect default sysctls specified in `containers.conf` allowing for advanced configuration of the namespaces they will share.
- SSH public key handling for remote Podman has been improved.

- Fixed a bug where root containers that did not explicitly specify a CNI network to join did not generate an entry for the network in use in the `Networks` field of the output of `podman inspect` ([#6618](https://github.com/containers/podman/issues/6618)).
- Fixed a bug where, under some circumstances, container working directories specified by the image (via the `WORKDIR` instruction) but not present in the image, would not be created ([#9040](https://github.com/containers/podman/issues/9040)).
- Fixed a bug where the `podman generate systemd` command would generate invalid unit files if the container was creating using a command line that included doubled braces (`{{` and `}}`), e.g. `--log-opt-tag={{.Name}}` ([#9034](https://github.com/containers/podman/issues/9034)).
- Fixed a bug where the `podman generate systemd --new` command could generate unit files including invalid Podman commands if the container was created using merged short options (e.g. `podman run -dt`) ([#8847](https://github.com/containers/podman/issues/8847)).
- Fixed a bug where the `podman generate systemd --new` command could generate unit files that did not handle Podman commands including some special characters (e.g. `$`) ([#9176](https://github.com/containers/podman/issues/9176)
- Fixed a bug where rootless containers joining CNI networks could not set a static IP address ([#7842](https://github.com/containers/podman/issues/7842)).
- Fixed a bug where rootless containers joining CNI networks could not set network aliases ([#8567](https://github.com/containers/podman/issues/8567)).
- Fixed a bug where the remote client could, under some circumstances, not include the `Containerfile` when sending build context to the server ([#8374](https://github.com/containers/podman/issues/8374)).
- Fixed a bug where rootless Podman did not mount `/sys` as a new `sysfs` in some circumstances where it was acceptable.
- Fixed a bug where rootless containers that both joined a user namespace and a CNI networks would cause a segfault. These options are incompatible and now return an error.

- Fixed a bug where the `podman play kube` command errored when `hostNetwork` was used ([#8790](https://github.com/containers/podman/issues/8790)).
- Fixed a bug where the `podman play kube` command would always pull images when the `:latest` tag was specified, even if the image was available locally ([#7838](https://github.com/containers/podman/issues/7838)).
- Fixed a bug where the `podman play kube` command did not properly handle SELinux configuration, rending YAML with custom SELinux configuration unusable ([#8710](https://github.com/containers/podman/issues/8710)).
- Fixed a bug where the `podman generate kube` command incorrectly populated the `args` and `command` fields of generated YAML ([#9211](https://github.com/containers/podman/issues/9211)).

- Fixed a bug where user-specified `HOSTNAME` environment variables were overwritten by Podman ([#8886](https://github.com/containers/podman/issues/8886)).
- Fixed a bug where Podman would applied default sysctls from `containers.conf` in too many situations (e.g. applying network sysctls when the container shared its network with a pod).
- Fixed a bug where Podman did not properly handle cases where a secondary image store was in use and an image was present in both the secondary and primary stores ([#8176](https://github.com/containers/podman/issues/8176)).
- Fixed a bug where systemd-managed rootless Podman containers where the user in the container was not root could fail as the container's PID file was not accessible to systemd on the host ([#8506](https://github.com/containers/podman/issues/8506)).
- Fixed a bug where the `--privileged` option to `podman run` and `podman create` would, under some circumstances, not disable Seccomp ([#8849](https://github.com/containers/podman/issues/8849)).
- Fixed a bug where the `podman exec` command did not properly add capabilities when the container or exec session were run with `--privileged`.
- Fixed a bug where rootless Podman would use the `--enable-sandbox` option to `slirp4netns` unconditionally, even when `pivot_root` was disabled, rendering `slirp4netns` unusable when `pivot_root` was disabled ([#8846](https://github.com/containers/podman/issues/8846)).
- Fixed a bug where `podman build --logfile` did not actually write the build's log to the logfile.

### Misc
- Updated Buildah to v1.19.2
- Updated the containers/storage library to v1.24.5
- Updated the containers/image library to v5.10.2
- Updated the containers/common library to v0.33.4

## v2.2.1
### Changes
- Due to a conflict with a previously-removed field, we were forced to modify the way image volumes (mounting images into containers using `--mount type=image`) were handled in the database. As a result, containers created in Podman 2.2.0 with image volumes will not have them in v2.2.1, and these containers will need to be re-created.

### Bugfixes
- Fixed a bug where rootless Podman would, on systems without the `XDG_RUNTIME_DIR` environment variable defined, use an incorrect path for the PID file of the Podman pause process, causing Podman to fail to start ([#8539](https://github.com/containers/podman/issues/8539)).
- Fixed a bug where containers created using Podman v1.7 and earlier were unusable in Podman due to JSON decode errors ([#8613](https://github.com/containers/podman/issues/8613)).
- Fixed a bug where Podman could retrieve invalid cgroup paths, instead of erroring, for containers that were not running.
- Fixed a bug where the `podman system reset` command would print a warning about a duplicate shutdown handler being registered.
- Fixed a bug where rootless Podman would attempt to mount `sysfs` in circumstances where it was not allowed; some OCI runtimes (notably `crun`) would fall back to alternatives and not fail, but others (notably `runc`) would fail to run containers.
- Fixed a bug where the `podman run` and `podman create` commands would fail to create containers from untagged images ([#8558](https://github.com/containers/podman/issues/8558)).
- Fixed a bug where remote Podman would prompt for a password even when the server did not support password authentication ([#8498](https://github.com/containers/podman/issues/8498)).
- Fixed a bug where the `podman exec` command did not move the Conmon process for the exec session into the correct cgroup.
- Fixed a bug where shell completion for the `ancestor` option to `podman ps --filter` did not work correctly.
- Fixed a bug where detached containers would not properly clean themselves up (or remove themselves if `--rm` was set) if the Podman command that created them was invoked with `--log-level=debug`.

### API
- Fixed a bug where the Compat Create endpoint for Containers did not properly handle the `Binds` and `Mounts` parameters in `HostConfig`.
- Fixed a bug where the Compat Create endpoint for Containers ignored the `Name` query parameter.
- Fixed a bug where the Compat Create endpoint for Containers did not properly handle the "default" value for `NetworkMode` (this value is used extensively by `docker-compose`) ([#8544](https://github.com/containers/podman/issues/8544)).
- Fixed a bug where the Compat Build endpoint for Images would sometimes incorrectly use the `target` query parameter as the image's tag.

### Misc
- Podman v2.2.0 vendored a non-released, custom version of the `github.com/spf13/cobra` package; this has been reverted to the latest upstream release to aid in packaging.
- Updated the containers/image library to v5.9.0

## 2.2.0
### Features
- Experimental support for shortname aliasing has been added. This is not enabled by default, but can be turned on by setting the environment variable `CONTAINERS_SHORT_NAME_ALIASING` to `on`. Documentation is [available here](https://github.com/containers/image/blob/master/docs/containers-registries.conf.5.md#short-name-aliasing).
- Initial support has been added for the `podman network connect` and `podman network disconnect` commands, which allow existing containers to modify what networks they are connected to. At present, these commands can only be used on running containers that did not specify `--network=none` when they were created.
- The `podman run` command now supports the `--network-alias` option to set network aliases (additional names the container can be accessed at from other containers via DNS if the `dnsname` CNI plugin is in use). Aliases can also be added and removed using the new `podman network connect` and `podman network disconnect` commands. Please note that this requires a new release (v1.1.0) of the `dnsname` plugin, and will only work on newly-created CNI networks.
- The `podman generate kube` command now features support for exporting container's memory and CPU limits ([#7855](https://github.com/containers/podman/issues/7855)).
- The `podman play kube` command now features support for setting CPU and Memory limits for containers ([#7742](https://github.com/containers/podman/issues/7742)).
- The `podman play kube` command now supports persistent volumes claims using Podman named volumes.
- The `podman play kube` command now supports Kubernetes configmaps via the `--configmap` option ([#7567](https://github.com/containers/podman/issues/7567)).
- The `podman play kube` command now supports a `--log-driver` option to set the log driver for created containers.
- The `podman play kube` command now supports a `--start` option, enabled by default, to start the pod after creating it. This allows for `podman play kube` to be more easily used in systemd unitfiles.
- The `podman network create` command now supports the `--ipv6` option to enable dual-stack IPv6 networking for created networks ([#7302](https://github.com/containers/podman/issues/7302)).
- The `podman inspect` command can now inspect pods, networks, and volumes, in addition to containers and images ([#6757](https://github.com/containers/podman/issues/6757)).
- The `--mount` option for `podman run` and `podman create` now supports a new type, `image`, to mount the contents of an image into the container at a given location.
- The Bash and ZSH completions have been completely reworked and have received significant enhancements! Additionally, support for Fish completions and completions for the `podman-remote` executable have been added.
- The `--log-opt` option for `podman create` and `podman run` now supports the `max-size` option to set the maximum size for a container's logs ([#7434](https://github.com/containers/podman/issues/7434)).
- The `--network` option to the `podman pod create` command now allows pods to be configured to use `slirp4netns` networking, even when run as root ([#6097](https://github.com/containers/podman/issues/6097)).
- The `podman pod stop`, `podman pod pause`, `podman pod unpause`, and `podman pod kill` commands now work on multiple containers in parallel and should be significantly faster.
- The `podman search` command now supports a `--list-tags` option to list all available tags for a single image in a single repository.
- The `podman search` command can now output JSON using the `--format=json` option.
- The `podman diff` and `podman mount` commands now work with all containers in the storage library, including those not created by Podman. This allows them to be used with Buildah and CRI-O containers.
- The `podman container exists` command now features a `--external` option to check if a container exists not just in Podman, but also in the storage library. This will allow Podman to identify Buildah and CRI-O containers.
- The `--tls-verify` and `--authfile` options have been enabled for use with remote Podman.
- The `/etc/hosts` file now includes the container's name and hostname (both pointing to localhost) when the container is run with `--net=none` ([#8095](https://github.com/containers/podman/issues/8095)).
- The `podman events` command now supports filtering events based on the labels of the container they occurred on using the `--filter label=key=value` option.
- The `podman volume ls` command now supports filtering volumes based on their labels using the `--filter label=key=value` option.
- The `--volume` and `--mount` options to `podman run` and `podman create` now support two new mount propagation options, `unbindable` and `runbindable`.
- The `name` and `id` filters for `podman pod ps` now match based on a regular expression, instead of requiring an exact match.
- The `podman pod ps` command now supports a new filter `status`, that matches pods in a certain state.

### Changes
- The `podman network rm --force` command will now also remove pods that are using the network ([#7791](https://github.com/containers/podman/issues/7791)).
- The `podman volume rm`, `podman network rm`, and `podman pod rm` commands now return exit code 1 if the object specified for removal does not exist, and exit code 2 if the object is in use and the `--force` option was not given.
- If `/dev/fuse` is passed into Podman containers as a device, Podman will open it before starting the container to ensure that the kernel module is loaded on the host and the device is usable in the container.
- Global Podman options that were not supported with remote operation have been removed from `podman-remote` (e.g. `--cgroup-manager`, `--storage-driver`).
- Many errors have been changed to remove repetition and be more clear as to what has gone wrong.
- The `--storage` option to `podman rm` is now enabled by default, with slightly changed semantics. If the given container does not exist in Podman but does exist in the storage library, it will be removed even without the `--storage` option. If the container exists in Podman it will be removed normally. The `--storage` option for `podman rm` is now deprecated and will be removed in a future release.
- The `--storage` option to `podman ps` has been renamed to `--external`. An alias has been added so the old form of the option will continue to work.
- Podman now delays the SIGTERM and SIGINT signals during container creation to ensure that Podman is not stopped midway through creating a container resulting in potential resource leakage ([#7941](https://github.com/containers/podman/issues/7941)).
- The `podman save` command now strips signatures from images it is exporting, as the formats we export to do not support signatures ([#7659](https://github.com/containers/podman/issues/7659)).
- A new `Degraded` state has been added to pods. Pods that have some, but not all, of their containers running are now considered to be `Degraded` instead of `Running`.
- Podman will now print a warning when conflicting network options related to port forwarding (e.g. `--publish` and `--net=host`) are specified when creating a container.
- The `--restart on-failure` and `--rm` options for containers no longer conflict. When both are specified, the container will be restarted if it exits with a non-zero error code, and removed if it exits cleanly ([#7906](https://github.com/containers/podman/issues/7906)).
- Remote Podman will no longer use settings from the client's `containers.conf`; defaults will instead be provided by the server's `containers.conf` ([#7657](https://github.com/containers/podman/issues/7657)).
- The `podman network rm` command now has a new alias, `podman network remove` ([#8402](https://github.com/containers/podman/issues/8402)).

- Fixed a bug where Podman's handling of capabilities, specifically inheritable, did not match Docker's.
- Fixed a bug where `podman run` would fail if the image specified was a manifest list and had already been pulled ([#7798](https://github.com/containers/podman/pull/7798)).
- Fixed a bug where Podman did not take search registries into account when looking up images locally ([#6381](https://github.com/containers/podman/issues/6381)).
- Fixed a bug where the `podman manifest inspect` command would fail for images that had already been pulled ([#7726](https://github.com/containers/podman/issues/7726)).
- Fixed a bug where rootless Podman would not add supplemental GIDs to containers when when a user, but not a group, was set via the `--user` option to `podman create` and `podman run` and sufficient GIDs were available to add the groups ([#7782](https://github.com/containers/podman/issues/7782)).
- Fixed a bug where remote Podman commands did not properly handle cases where the user gave a name that could also be a short ID for a pod or container ([#7837](https://github.com/containers/podman/issues/7837)).

- Fixed a bug where the `--format "table {{ .Field }}"` option to numerous Podman commands ceased to function on Podman v2.0 and up.
- Fixed a bug where pods did not properly share an SELinux label between their containers, resulting in containers being unable to see the processes of other containers when the pod shared a PID namespace ([#7886](https://github.com/containers/podman/issues/7886)).
- Fixed a bug where the `--namespace` option to `podman ps` did not work with the remote client ([#7903](https://github.com/containers/podman/issues/7903)).

- Fixed a bug where the `-p` option to `podman run`, `podman create`, and `podman pod create` would, when given only a single number (e.g. `-p 80`), assign the same port for both host and container, instead of generating a random host port ([#7947](https://github.com/containers/podman/issues/7947)).
- Fixed a bug where Podman containers did not properly store the cgroup manager they were created with, causing them to stop functioning after the cgroup manager was changed in `containers.conf` or with the `--cgroup-manager` option ([#7830](https://github.com/containers/podman/issues/7830)).

- Fixed a bug where the `podman run` and `podman start --attach` commands would exit with an error when the user detached manually using the detach keys on remote Podman ([#7979](https://github.com/containers/podman/issues/7979)).
- Fixed a bug where rootless CNI networking did not use the `dnsname` CNI plugin if it was not available on the host, despite it always being available in the container used for rootless networking ([#8040](https://github.com/containers/podman/issues/8040)).
- Fixed a bug where Podman did not properly handle cases where an OCI runtime is specified by its full path, and could revert to using another OCI runtime with the same binary path that existed in the system `$PATH` on subsequent invocations.
- Fixed a bug where the `--net=host` option to `podman create` and `podman run` would cause the `/etc/hosts` file to be incorrectly populated ([#8054](https://github.com/containers/podman/issues/8054)).

### Features
- A new command, `podman image mount`, has been added. This allows for an image to be mounted, read-only, to inspect its contents without creating a container from it ([#1433](https://github.com/containers/podman/issues/1433)).
- The `podman save` and `podman load` commands can now create and load archives containing multiple images ([#2669](https://github.com/containers/podman/issues/2669)).
- Rootless Podman now supports all `podman network` commands, and rootless containers can now be joined to networks.
- The performance of `podman build` on `ADD` and `COPY` instructions has been greatly improved, especially when a `.dockerignore` is present.
- The `podman run` and `podman create` commands now support a new mode for the `--cgroups` option, `--cgroups=split`. Podman will create two cgroups under the cgroup it was launched in, one for the container and one for Conmon. This mode is useful for running Podman in a systemd unit, as it ensures that all processes are retained in systemd's cgroup hierarchy ([#6400](https://github.com/containers/podman/issues/6400)).
- The `podman run` and `podman create` commands can now specify options to slirp4netns by using the `--network` option as follows:  `--net slirp4netns:opt1,opt2`. This allows for, among other things, switching the port forwarder used by slirp4netns away from rootlessport.
- The `podman ps` command now features a new option, `--storage`, to show containers from Buildah, CRI-O and other applications.
- The `podman run` and `podman create` commands now feature a `--sdnotify` option to control the behavior of systemd's sdnotify with containers, enabling improved support for Podman in `Type=notify` units.
- The `podman run` command now features a `--preserve-fds` option to pass file descriptors from the host into the container ([#6458](https://github.com/containers/podman/issues/6458)).
- The `podman run` and `podman create` commands can now create overlay volume mounts, by adding the `:O` option to a bind mount (e.g. `-v /test:/test:O`). Overlay volume mounts will mount a directory into a container from the host and allow changes to it, but not write those changes back to the directory on the host.
- The `podman play kube` command now supports the Socket HostPath type ([#7112](https://github.com/containers/podman/issues/7112)).
- The `podman play kube` command now supports read-only mounts.
- The `podman play kube` command now supports setting labels on pods from Kubernetes metadata labels.
- The `podman play kube` command now supports setting container restart policy ([#7656](https://github.com/containers/podman/issues/7656)).
- The `podman play kube` command now properly handles `HostAlias` entries.
- The `podman generate kube` command now adds entries to `/etc/hosts` from `--host-add` generated YAML as `HostAlias` entries.
- The `podman play kube` and `podman generate kube` commands now properly support `shareProcessNamespace` to share the PID namespace in pods.
- The `podman volume ls` command now supports the `dangling` filter to identify volumes that are dangling (not attached to any container).
- The `podman run` and `podman create` commands now feature a `--umask` option to set the umask of the created container.
- The `podman create` and `podman run` commands now feature a `--tz` option to set the timezone within the container ([#5128](https://github.com/containers/podman/issues/5128)).
- Environment variables for Podman can now be added in the `containers.conf` configuration file.
- The `--mount` option of `podman run` and `podman create` now supports a new mount type, `type=devpts`, to add a `devpts` mount to the container. This is useful for containers that want to mount `/dev/` from the host into the container, but still create a terminal.
- The `--security-opt` flag to `podman run` and `podman create` now supports a new option, `proc-opts`, to specify options for the container's `/proc` filesystem.
- Podman with the `crun` OCI runtime now supports a new option to `podman run` and `podman create`, `--cgroup-conf`, which allows for advanced configuration of cgroups on cgroups v2 systems.
- The `podman create` and `podman run` commands now support a `--override-variant` option, to override the architecture variant of the image that will be pulled and ran.
- A new global option has been added to Podman, `--runtime-flags`, which allows for setting flags to use when the OCI runtime is called.
- The `podman manifest add` command now supports the `--cert-dir`, `--auth-file`, `--creds`, and `--tls-verify` options.

### Security
- This release resolves CVE-2020-14370, in which environment variables could be leaked between containers created using the Varlink API.

### Changes
- Podman will now retry pulling an image 3 times if a pull fails due to network errors.
- The `podman exec` command would previously print error messages (e.g. `exec session exited with non-zero exit code -1`) when the command run exited with a non-0 exit code. It no longer does this. The `podman exec` command will still exit with the same exit code as the command run in the container did.
- Error messages when creating a container or pod with a name that is already in use have been improved.
- For read-only containers running systemd init, Podman creates a tmpfs filesystem at `/run`. This was previously limited to 65k in size and mounted `noexec`, but is now unlimited size and mounted `exec`.
- The `podman system reset` command no longer removes configuration files for rootless Podman.

### Bugfixes
- Fixed a bug where Podman would not add an entry to `/etc/hosts` for a container if it joined another container's network namespace ([#66782](https://github.com/containers/podman/issues/6678)).

- Fixed a bug where the `podman ps` was ignoring the `--latest` flag.
- Fixed a bug where the `podman-remote kill` command would hang when a signal that did not kill the container was specified ([#7135](https://github.com/containers/podman/issues/7135)).

- Fixed a bug where the `podman wait` command would only accept a single argument.
- Fixed a bug where the parsing of the `--volumes-from` option to `podman run` and `podman create` was broken, making it impossible to use multiple mount options at the same time ([#7701](https://github.com/containers/podman/issues/7701)).

- Fixed a bug where the `CgroupVersion` field in responses from the compat Info endpoint was prefixed by "v" (instead of just being "1" or "2", as is documented).

## 2.0.3
### Features
- The `podman search` command now allows wildcards in search terms.
- The `podman play kube` command now supports the `IfNotPresent` pull type.

### Changes
- The `--disable-content-trust` flag has been added to Podman for Docker compatibility. This is a Docker-specific option and has no effect in Podman; it is provided only to ensure command line compatibility for scripts ([#7034](https://github.com/containers/podman/issues/7034)).
- Setting a static IP address or MAC address for rootless containers and pods now causes an error; previously, they were silently ignored.
- The `/sys/dev` folder is now masked in containers to prevent a potential information leak from the host.

- Fixed a bug where the `podman images` command would display incorrect tags if a port number was included in the repository.
- Fixed a bug where Podman did not set a default umask and default rlimits ([#6989](https://github.com/containers/podman/issues/6989)).
- Fixed a bug where protocols in port mappings were not recognized unless they were lower-case ([#6948](https://github.com/containers/podman/issues/6948)).
- Fixed a bug where information on pod infra containers was not included in the output of `podman pod inspect`.
- Fixed a bug where Podman's systemd detection (activated by the enabled-by-default `--systemd=true` flag) would not flag a container for systemd mode if systemd was part of the entrypoint, not the command ([#6920](https://github.com/containers/podman/issues/6920)).
- Fixed a bug where `podman start --attach` was not defaulting `--sig-proxy` to true ([#6928](https://github.com/containers/podman/issues/6928)).
- Fixed a bug where `podman inspect` would show an incorrect command (`podman system service`, the command used to start the server) for containers created by a remote Podman client.

- Fixed a bug where some variations of the `--format {{ json . }}` to `podman info` (involving added or removed whitespace) would not be accepted ([#6927](https://github.com/containers/podman/issues/6927)).
- Fixed a bug where Entrypoint could not be cleared at the command line (if unset via `--entrypoint=""`, it would be reset to the image's entrypoint) ([#6935](https://github.com/containers/podman/issues/6935)).

### API
- Fixed a bug where the events endpoints (both libpod and compat) could potentially panic on parsing filters.
- Fixed a bug where the compat Create endpoint for containers did not properly handle Entrypoint and Command.
- Fixed a bug where the Logs endpoint for containers (both libpod and compat) would not properly handle client disconnect, resulting in high CPU usage.
- The type of filters on the compat events endpoint has been adjusted to match Docker's implementation ([#6899](https://github.com/containers/podman/issues/6899)).
- The idle connection counter now properly handles hijacked connections.
- All endpoints that hijack will now properly print headers per RFC 7230 standards.

### Misc
- Updated containers/common to v0.14.6

## 2.0.2
### Changes
- The `podman system connection` command has been temporarily disabled, as it was not functioning as expected.

### Bugfixes
- Fixed a bug where the `podman ps` command would not truncate long container commands, resulting in display issues as the column could become extremely wide (the `--no-trunc` flag can be used to print the full command).
- Fixed a bug where `podman pod` commands operating on multiple containers (e.g. `podman pod stop` and `podman pod kill`) would not print errors from individual containers, but only a warning that some containers had failed.
- Fixed a bug where the `podman system service` command would panic if a connection to the Events endpoint hung up early ([#6805](https://github.com/containers/libpod/issues/6805)).
- Fixed a bug where rootless Podman would create anonymous and named volumes with the wrong owner for containers run with the `--user` directive.

- Fixed a bug where the `--remote` flag to Podman required an argument, despite being a boolean ([#6704](https://github.com/containers/libpod/issues/6704)).
- Fixed a bug where the `podman generate systemd --new` command could generate incorrect unit files for a pod if a container in the pod was created using the `--pod=...` flag (with an =, instead of a space, before the pod ID) ([#6766](https://github.com/containers/libpod/issues/6766)).
- Fixed a bug where `NPROC` and `NOFILE` rlimits could be improperly set for rootless Podman containers, causing them to fail to start.

- Fixed a bug where unit files generated for pods by `podman generate systemd` would not allow individual containers to be restarted ([#6770](https://github.com/containers/libpod/issues/6770)).
- Fixed a bug where the `podman run` and `podman create` commands did not support all transports that `podman pull` does ([#6744](https://github.com/containers/libpod/issues/6744)).
- Fixed a bug where the `label` option to `--security-opt` would only be shown once in `podman inspect`, even if provided multiple times.

### API

- Podman previously did not allow the creation of containers with a memory limit lower than 4MB. This restriction has been removed, as the `crun` runtime can create containers with significantly less memory

## 1.6.3
### Features
- Handling of the `libpod.conf` configuration file has seen major changes. Most significantly, rootless users will no longer automatically receive a complete configuration file when they first use Podman, and will instead only receive differences from the global configuration.
- Initial support for the CNI DNS plugin, which allows containers to resolve the IPs of other containers via DNS name, has been added
- Podman now supports anonymous named volumes, created by specifying only a destination to the `-v` flag to the `podman create` and `podman run` commands
- Named volumes now support `uid` and `gid` options in `--opt o=...` to set UID and GID of the created volume

### Bugfixes
- Fixed a bug where the `podman start` command would print container ID, instead of name, when starting containers given their name
- Fixed a bug where named volumes with options did not properly detect issues with mounting the volume, leading to an inconsistent state ([#4303](https://github.com/containers/podman/issues/4303))

- Fixed a bug where the `podman volume inspect` command would not show the options that named volumes were created with
- Fixed a bug where custom storage configuration was not written to `storage.conf` at time of first creation for rootless Podman ([#2659](https://github.com/containers/podman/issues/2659))
- Fixed a bug where remote Podman did not support shell redirection of container output

### Misc
- Updated vendored containers/image library to v5.0
- Initial support for images using manifest lists has been added, though commands for directly interacting with manifests are still missing
- Support for pushing to and pulling from OSTree has been removed due to deprecation in the containers/image library
- Rootless Podman no longer enables linger on systems with systemd as init by default. As such, containers will now be killed when the user who ran them logs out, unless linger is explicitly enabled using [loginctl](https://www.freedesktop.org/software/systemd/man/loginctl.html)
- Podman will now check the version of `conmon` that is in use to ensure it is sufficient

## 1.6.2
### Features
- Added a `--runtime` flag to `podman system migrate` to allow the OCI runtime for all containers to be reset, to ease transition to the `crun` runtime on CGroups V2 systems until `runc` gains full support
- The `podman rm` command can now remove containers in broken states which previously could not be removed
- The `podman info` command, when run without root, now shows information on UID and GID mappings in the rootless user namespace
- Added `podman build --squash-all` flag, which squashes all layers (including those of the base image) into one layer
- The `--systemd` flag to `podman run` and `podman create` now accepts a string argument and allows a new value, `always`, which forces systemd support without checking if the the container entrypoint is systemd

### Bugfixes
- Fixed a bug where the `podman top` command did not work on systems using CGroups V2 ([#4192](https://github.com/containers/podman/issues/4192))
- Fixed a bug where rootless Podman could double-close a file, leading to a panic
- Fixed a bug where rootless Podman could fail to retrieve some containers while refreshing the state
- Fixed a bug where `podman start --attach --sig-proxy=false` would still proxy signals into the container
- Fixed a bug where Podman would unconditionally use a non-default path for authentication credentials (`auth.json`), breaking `podman login` integration with `skopeo` and other tools using the containers/image library
- Fixed a bug where `podman ps --format=json` and `podman images --format=json` would display `null` when no results were returned, instead of valid JSON
- Fixed a bug where `podman build --squash` was incorrectly squashing all layers into one, instead of only new layers
- Fixed a bug where rootless Podman would allow volumes with options to be mounted (mounting volumes requires root), creating an inconsistent state where volumes reported as mounted but were not ([#4248](https://github.com/containers/podman/issues/4248))
- Fixed a bug where volumes which failed to unmount could not be removed ([#4247](https://github.com/containers/podman/issues/4247))
- Fixed a bug where Podman incorrectly handled some errors relating to unmounted or missing containers in containers/storage
- Fixed a bug where `podman stats` was broken on systems running CGroups V2 when run rootless ([#4268](https://github.com/containers/podman/issues/4268))
- Fixed a bug where the `podman start` command would print the short container ID, instead of the full ID
- Fixed a bug where containers created with an OCI runtime that is no longer available (uninstalled or removed from the config file) would not appear in `podman ps` and could not be removed via `podman rm`
- Fixed a bug where containers restored via `podman container restore --import` would retain the CGroup path of the original container, even if their container ID changed; thus, multiple containers created from the same checkpoint would all share the same CGroup

### Misc
- The default PID limit for containers is now set to 4096. It can be adjusted back to the old default (unlimited) by passing `--pids-limit 0` to `podman create` and `podman run`
- The `podman start --attach` command now automatically attaches `STDIN` if the container was created with `-i`
- The `podman network create` command now validates network names using the same regular expression as container and pod names
- The `--systemd` flag to `podman run` and `podman create` will now only enable systemd mode when the binary being run inside the container is `/sbin/init`, `/usr/sbin/init`, or ends in `systemd` (previously detected any path ending in `init` or `systemd`)
- Updated vendored Buildah to 1.11.3
- Updated vendored containers/storage to 1.13.5

- The `podman volume create` command can now create and mount volumes with options, allowing volumes backed by NFS, tmpfs, and many other filesystems
- Podman can now run containers without CGroups for better integration with systemd by using the `--cgroups=disabled` flag with `podman create` and `podman run`. This is presently only supported with the `crun` OCI runtime
- The `podman volume rm` and `podman volume inspect` commands can now refer to volumes by an unambiguous partial name, in addition to full name (e.g. `podman volume rm myvol` to remove a volume named `myvolume`) ([#3891](https://github.com/containers/podman/issues/3891))

- The `podman rm` and `podman rmi` commands now use different exit codes to indicate 'no such container' and 'container is running' errors
- Support for CGroups V2 through the `crun` OCI runtime has been greatly improved, allowing resource limits to be set for rootless containers when the CGroups V2 hierarchy is in use

### Bugfixes

- Fixed a bug where `podman run` with the `--user` flag would fail if the container image did not contain `/etc/passwd` or `/etc/group`

### Misc
- `podman rm`, `podman restart`, `podman kill`, `podman pause`, and `podman unpause` now operate in parallel, greatly improving speed when multiple containers are specified
- `podman create`, `podman run`, and `podman ps` have a number of improvements which should greatly increase their speed
- Greatly improved performance and reduced memory utilization of container status checks, which should improve the speed of most Podman commands

- Fixed rootless `podman create` with no command specified throwing an error

### Misc
- Added `podman rm --volumes` flag for compatibility with Docker. As Podman does not presently support named volumes, this does nothing for now, but provides improved compatibility with the Docker command line.
- Improved error messages from `podman pull`

### Compatibility
- Podman is no longer being built by default with support for the Devicemapper storage driver. If you are using this storage driver, you should investigate switching to overlayfs.

## 0.9.1.1
### Bugfixes
- Added support for configuring iptables and firewalld firewalls to allow container traffic. This should resolve numerous issues with network access in containers.

### Note
It is recommended that you restart your system firewall after installing this release to clear any firewall rules created by older Podman versions. If port forwarding to containers does not work, it is recommended that you restart your system.

## 0.9.1
### Features
- Added initial support for the `podman pod` command as non-root

### Bugfixes
- Fixed regression where invalid Podman commands would still cause a clean exit
- Fixed `podman rmi --all` to not error if no images are present on the system
- Fixed parsing of container logs with `podman logs` to properly handle CRI logging, fixing some issues with blank lines in logs
- Fixed a bug creating pod cgroups using the systemd cgroup driver with systemd versions 239 and higher
- Fixed handling of volume mounts that overlapped with default container mounts (for example, `podman run -v /dev/:/dev`)
- Fixed sharing of UTS namespace in pods

### Misc
- Added additional debug information when pulling images if `--log-level=debug` is specified
- `podman build` now defaults to caching intermediate layers while building

## 0.8.5
### Features
- Added the ability to add a multipart entrypoint with `podman run --entrypoint`
- Improved help text when invalid commands are specified
- Greatly improved support for containers which use systemd as init

### Bugfixes
- Fixed several bugs with rootless `podman exec`
- Fixed rootless `podman` with a symlinked storage directory crashing
- Fixed bug with `podman ps` and multiple filters where the interface did not match Docker
- Fixed handling of `resolv.conf` on the host to handle symlinks
- Increased open file descriptor and process limits to match Docker and Buildah
- Fixed `podman run -h` to specify the container's hostname (as it does in Docker) instead of printing help text
- Fixed a bug with image shortname handling where repositories were incorrectly being treated as registries
- Fixed a bug where `podman wait` was busywaiting and consuming large amounts of CPU

## 0.8.4
### Features
- Added the `podman pod top` command
- Added the ability to easily share namespaces within a pod
- Added a pod statistics endpoint to the Varlink API
- Added information on container capabilities to the output of `podman inspect`

### Bugfixes
- Fixed a bug with the --device flag in `podman run` and `podman create`
- Fixed `podman pod stats` to accept partial pod IDs and pod names
- Fixed a bug with OCI hooks handling `ALWAYS` matches
- Fixed a bug with privileged rootless containers with `--net=host` set
- Fixed a bug where `podman exec --user` would not work with usernames, only numeric IDs
- Fixed a bug where Podman was forwarding both TCP and UDP ports to containers when protocol was not specified
- Fixed issues with Apparmor in rootless containers
- Fixed an issue with database encoding causing some containers created by Podman versions 0.8.1 and below to be unusable.

### Compatibility:
We switched JSON encoding/decoding to a new library for this release to address a compatibility issue introduced by v0.8.2.
However, this may cause issues with containers created in 0.8.2 and 0.8.3 with custom DNS servers.
