### Misc
- Podman migrated to a new, shared memory locking model in this release. As part of this, if you are running Podman with pods or dependency containers (e.g. `--net=container:`), you should run the `podman system renumber` command to migrate your containers to the new model - please reference the `podman-system-renumber(1)` man page for further details

## 0.12.1
### Features
- Rootless Podman now creates the storage.conf, libpod.conf, and mounts.conf configuration files automatically in `~/.config/containers/` for ease of reconfiguration
- The `podman pod create` command can expose ports in the pod's network namespace, allowing public services to be created in pods
- The `podman container checkpoint` command can now keep containers running after they are checkpointed with the `--leave-running` flag

- The `podman rmi` and `podman rm` commands now have a `--prune` flag to prune unused images and containers, respectively
- The `podman ps` command now has a `--sync` flag to force a sync of Podman's state against the OCI runtime, resolving some state desync errors
- Added the `podman volume` set of commands for creating and managing local-only named volumes

### Bugfixes
- Fixed a breaking change in rootless Podman where a change in default paths caused Podman to be unable to function on systems upgraded from 0.10.x or earlier
- Fixed a bug where `podman exec` without `-t` would still use a terminal if the container was created with `-t`
- Fixed a bug where container root propogation was not being properly adjusted if volumes with root propogation set were mounted into the container
- Fixed a bug where `podman exec` could hold the container lock longer than necessary waiting for an exited container
- Fixed a bug where rootless containers using `slirp4netns` for networking were reporting using `bridge` networking in `podman inspect`
- Fixed a bug where `podman container restore -a` was attempting to restore all containers, including created and running ones. It will now only attempt to restore stopped and exited containers
- Fixed a bug where rootless Podman detached containers were not being properly cleaned up
- Fixed a bug where privileged containers were being mounted with incorrect (too restrictive) mount options such as `nodev`
- Fixed a bug where `podman stop` would throw an error attempting to stop a container that had already stopped

- Fixed a bug where Podman would error on numeric GIDs that do not exist in the container's `/etc/group`
- Fixed a bug where containers in pods or created with `--net=container` were not mounting `/etc/resolv.conf` and `/etc/hosts`

### Misc
- `podman build` now defaults the `--force-rm` flag to `true`
- Improved `podman runlabel` support for labels featuring arguments with whitespace
- Containers without a network namespace will now use the host's `resolv.conf`
- The `slirp4netns` network mode can now be used with containers running as root. It may be useful for container-in-container scenarios where the outer container does not have host networking set
- Podman now uses `inotify` to wait for container exit files to be created, instead of polling. If `inotify` cannot be used, Podman will fall back to polling to check if the file has been created
- The `podman logs` command now uses improved short-options handling, allowing its flags to be combined if desired (for example, `podman logs -lf` instead of `podman logs -l -f`)
- Hardcoded OCI hooks directories used by Podman are now deprecated; they should instead be coded into the `libpod.conf` configuration file. They can be specified as an array via `hooks_dir`

### Bugfixes
- Fixed a bug where Podman was not correctly adding firewall rules for containers, preventing them from accessing the network
- Fixed a bug where full error messages were being lost when creating containers with user namespaces
- Fixed a bug where container state was not properly updated if a failure occurred during network setup, which could cause mounts to be left behind when the container was removed
- Fixed a bug where `podman exec` could time out on slower systems by increasing the relevant timeout

### Misc
- `podman rm -f` now removes paused containers. As such, `podman rm -af` completing successfully guarantees all Podman containers have been removed
- Added a field to `podman info` to show if Podman is being run as rootless
- Made a small output format change to `podman images` - image sizes now feature a space between number and unit (e.g. `123 MB` now instead of `123MB`)
- Vendored an updated version of `containers/storage` to fix several bugs reported upstream

## 0.11.1
### Features
- Added `--all` and `--latest` flags to `podman checkpoint` and `podman restore`
- Added `--max-workers` flag to all Podman commands that support operating in parallel, allowing the maximum number of parallel workers used to be specified

- Fixed a bug where `podman stats -a` would error if containers were present but not running
- Fixed a bug where container status checks would sometimes leave zombie OCI runtime processes
- Fixed checkpoint and restore code to verify an appropriate version of `criu` is being used
- Fixed a bug where environment variables with no specified value (e.g. `-e FOO`) caused errors (they are now added as empty)

- Fixed a bug where `podman info` was not properly reporting the Git commit Podman was built from
- Fixed a bug where `podman run --interactive` was not holding STDIN open when `-a` flag was specified
- Fixed a bug where Podman with the `cgroupfs` CGroup driver was sometimes not successfully removing pod CGroups
- Fixed a bug where rootless Podman was unable to run systemd containers (note that this also requires an update to systemd)
- 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
- Improve ability of `podman runlabel` to run commands that are not Podman
- Podman containers with an IP address now add their hostnames to `/etc/hosts`
- Changed default location of temporary libpod files in rootless Podman
- Updated the default Podman seccomp profile

### Compatability
Several paths related to rootless Podman had their default values changed in this release.
If paths were not hardcoded in libpod.conf, your system may lose track of running containers and believe they are newly-created.

## 0.10.1.3
### Bugfixes
- Fixed a bug where `podman build` would not work while any containers were running

## 0.10.1.2
### Bugfixes
- Fixed cgroup mount for containers using systemd as init to work properly with the systemd cgroup manager

## 0.10.1.1
### Features
- Added handling for running containers as users with numeric UIDs not present in the container's /etc/passwd. This allows getpwuid() to work inside these containers.
- Added support for the REGISTRY_AUTH_FILE environment variable, which specifies the location of credentials for registry login. This is supported by the `push`, `pull`, `login`, `logout`, `runlabel`, and `search` commands

### Bugfixes
- Fixed handling for image volumes which are mounted on symlinks. The links are now resolved within the container, not on the host

### Features
- Added a flag to `libpod.conf`, `label`, to globally enable/disable SELinux labelling for libpod
- Added `--mount` flag to `podman create` and `podman run` as a new, more explicit way of specifying volume mounts

### Bugfixes

- Fixed rootless Podman to properly join the namespaces of other containers
- Fixed the output of `podman diff` to not display some default changes that will not be committed
- Fixed rootless to better handle cases where insufficient UIDs/GIDs are mapped into the container

## 0.9.2.1
### Bugfixes
- Updated Buildah dependency to fix several bugs in `podman build`

### Misc
- Small performance improvement in image handling code to not recalculate digests

## 0.9.2
### Features
- Added `--interval` flag to `podman wait` to determine the interval between checks for container status
- Added a switch in `libpod.conf` to disable reserving ports for running containers. This lowers the safety of port allocations, but can significantly reduce memory usage.
- Added ability to search all the contents of a registry if no image name is specified when using `podman search`

### Bugfixes
- Further fixes for sharing of UTS namespaces within pods
- Fixed a deadlock in containers/storage that could be caused by numerous parallel Podman processes.
- Fixed Podman running into open file limits when many ports are forwarded
- Fixed default mount propagation on volume mounts
- Fixed default mounts under /dev remaining if /dev is bind-mounted into the container
- Fixed rootless `podman create` with no command specified throwing an error

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

### Compatability
- 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.

### Compatability:
We switched JSON encoding/decoding to a new library for this release to address a compatability 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.
