Changes
- CNI is being deprecated from Podman and support will be dropped at a future date. Netavark is now advised and is the default network backend for Podman.
- The network name `pasta` is deprecated and support for it will be removed in the next major release.
- The `podman network create` command no longer accepts `default` as valid name. It is impossible to use this network name in the `podman run/create` command because it is parsed as a network mode instead ([17169](https://github.com/containers/podman/issues/17169)).
- The `podman kube generate` command will no longer generate built-in annotations, as reserved annotations are used internally by Podman and would have no effect when run with Kubernetes.
- The `podman kube play` command now limits the replica count to 1 when deploying from kubernetes YAML ([16765](https://github.com/containers/podman/issues/16765)).
- When a container that runs with the `--pid=host` option is terminated, Podman now sends a SIGKILL to all the active exec sessions
- The journald driver for both `podman events` and `podman logs` is now more efficient when the `--since` option is used, as it will now seek directly to the correct time instead of reading all entries from the journal ([16950](https://github.com/containers/podman/issues/16950)).
- When the `--service-container` option is set for the `podman kube play` command, the default log-driver to is now set to `passthrough` ([16592](https://github.com/containers/podman/issues/16592)).
- The `podman container inspect` and `podman kube generate` commands will no longer list default annotations set to false.
- Podman no longer reports errors on short-lived init containers in pods.
- Healthchecks are now automatically disabled if on non-systemd systems. If Podman is compiled without the systemd build tag, healthcheck will be disabled at build time ([16644](https://github.com/containers/podman/issues/16644)).
- Improved atomicity of VM state persistence on Windows now better tolerates FS corruption in cases of power loss or system failure ([16550](https://github.com/containers/podman/issues/16550)).
- A user namespace is now always created when running with EUID != 0. This is necessary to work in a Kubernetes environment where the POD is "privileged" but it is still running with a non-root user.
- Old healthcheck states are now cleaned up during container restart.
- The `CONTAINER_HOST` environment variable defaults to port 22 for SSH style URLs for remote connections, when set ([16509](https://github.com/containers/podman/issues/16509)).
- The `podman kube play` command now reuses existing PersistentVolumeClaims instead of erroring.
- The `podman system reset` command will no longer prompt the user if `/usr/share/containers/storage.conf` file exists.
- Existing container/pod id files are now truncated instead of throwing an error.
- The `--format` and `--verbose` flags in `podman system df` are no longer allowed to be used in combination.
- The `podman kube generate` command now sets `runAsNonRoot=true` in the generated yaml when the image has user set as a positive integer ([15231](https://github.com/containers/podman/issues/15231)).
- Listing containers (e.g, via `podman ps`) is considerably faster.
- The `podman push` and `podman manifest push` commands now support a new option, `--sign-by-sigstore`, which allows using Fulcio and Rekor.

Bugfixes
