Features
- The `podman cp` command can now read input redirected to `STDIN`, and output to `STDOUT` instead of a file, using `-` instead of an argument.
- The Podman remote client now displays version information from both the client and server in `podman version`
- The `podman unshare` command has been added, allowing easy entry into the user namespace set up by rootless Podman (allowing the removal of files created by rootless Podman, among other things)
Bugfixes
- Fixed a bug where Podman containers with the `--rm` flag were removing created volumes when they were automatically removed ([3071](https://github.com/containers/libpod/issues/3071))
- Fixed a bug where container and pod locks were incorrectly marked as released after a system reboot, causing errors on container and pod removal ([2900](https://github.com/containers/libpod/issues/2900))
- Fixed a bug where Podman pods could not be removed if any container in the pod encountered an error during removal ([3088](https://github.com/containers/libpod/issues/3088))
- Fixed a bug where Podman pods run with the `cgroupfs` CGroup driver would encounter a race condition during removal, potentially failing to remove the pod CGroup
- Fixed a bug where the `podman container checkpoint` and `podman container restore` commands were not visible in the remote client
- Fixed a bug where `podman remote ps --ns` would not print the container's namespaces ([2938](https://github.com/containers/libpod/issues/2938))
- Fixed a bug where removing stopped containers with healthchecks could cause an error
- Fixed a bug where the default `libpod.conf` file was causing parsing errors ([3095](https://github.com/containers/libpod/issues/3095))
- Fixed a bug where pod locks were not being freed when pods were removed, potentially leading to lock exhaustion
- Fixed a bug where 'podman run' with SD_NOTIFY set could, on short-running containers, create an inconsistent state rendering the container unusable
Misc
- The remote Podman client now uses the Varlink bridge to establish remote connections by default
- The MacOS dmg file is experimental, use at your own risk. But we would like to hear the results.
