Features

• The podman manifest inspect command now supports the --authfile option, for authentication purposes.
• The podman wait command now supports --condition={healthy,unhealthy}, allowing waits on successful health checks.
• The podman push command now supports a new option, --compression-level, which specifies the compression level to use (#18939).
• The podman machine start command, when run with --log-level=debug, now creates a console window to display the virtual machine while booting.
• Podman now supports a new option, --imagestore, which allows images to be stored in a different directory than the graphroot.
• The --ip-range option to the podman network create command now accepts a new syntax, <startIP>-<endIP>, which allows more flexibility when limiting the ip range that Podman assigns.
• [Tech Preview] A new command, podmansh, has been added, which executes a user shell within a container when the user logs into the system. The container that the users get added to can be defined via a Podman Quadlet file. This feature is currently a Tech Preview which means it's ready for users to try out but changes can be expected in upcoming versions.

• Podman now supports a new option, --out, that allows redirection or suppression of STDOUT (#18120).

Changes

Bugfixes

• Fixed a bug where the podman machine start command would fail with a 255 exit code. It now waits for systemd-user sessions to be up, and for SSH to be ready, addressing the flaky machine starts (#17403).
• Fixed a bug where the podman auto update command did not correctly use authentication files when contacting container registries.
• Fixed a bug where the --dns option to the podman run command was ignored for macvlan networks (#19169).
• Fixed a bug in the podman system service command where setting LISTEN_FDS when listening on TCP would misbehave.
• Fixed a bug where hostnames were not recognized as a network alias. Containers can now resolve other hostnames, in addition to their names (#17370).
• Fixed a bug where the podman pod run command would error after a reboot on a non-systemd system (#19175).
• Fixed a bug where the --syslog option returned a fatal error when no syslog server was found (#19075).
• Fixed a bug where the --mount option would parse the readonly option incorrectly (#18995).
• Fixed a bug where hook executables invoked by the podman run command set an incorrect working directory. It now sets the correct working directory pointing to the container bundle directory (#18907).
• Fixed a bug where the -device-cgroup-rule option was silently ignored in rootless mode (#18698).
• Listing images is now more resilient towards concurrently running image removals.

• Fixed a bug where the podman auto-update command would not restart dependent units (specified via Requires=) on auto update (#18926).

• Fixed a bug where creating a container while setting unmask option to an empty array would cause the create to fail (#18848).
• Fixed a bug where the propagation of proxy settings for QEMU VMs was broken.
• Fixed a bug where the podman rm -fa command could fail to remove dependency containers such as pod infra containers (#18180).
• Fixed a bug where --tz option to the podman create and podman run commands would not create a proper localtime symlink to the zoneinfo file, which was causing some applications (e.g. java) to not read the timezone correctly.
• Fixed a bug where lowering the ulimit after container creation would cause the container to fail (#18714).
• Fixed a bug where signals were not forwarded correctly in rootless containers (#16091).
• Fixed a bug where the --filter volume= option to the podman events command would not display the relevant events (#18618).

• Fixed a bug where the podman stats command returned an incorrect memory limit after a container update. (#18621).
• Fixed a bug in the podman run command where the PODMAN_USERNS environment variable was not ignored when the --pod option was set, resulting in a container created in a different user namespace than its pod (#18580).
• Fixed a bug where the podman run command would not create the /run/.containerenv when the tmpfs is mounted on /run (#18531).
• Fixed a bug where the $HOME environment variable would be configured inconsistently between container starts if a new passwd entry had to be created for the container.

• Fixed a bug where a podman machine could get stuck in the starting state (#16945).

• Fixed a bug where the --format {{.State}} option to the podman ps command would display the status rather than the state (#18244).
