Podman (the POD MANager) is a tool for managing containers and images, volumes mounted into those containers, and pods made from groups of containers.
Podman is based on libpod, a library for container lifecycle management that is also contained in this repository. The libpod library provides APIs for managing containers, pods, container images, and 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 `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 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)).

+- Libpod API version has been bumped to v3.0.0.
+- All Libpod Pod APIs have been modified to properly report errors with individual containers. Cases where the operation as a whole succeeded but individual containers failed now report an HTTP 409 error ([#8865](https://github.com/containers/podman/issues/8865)).
