- Fixed a bug where improperly formatted annotations passed to `podman kube play` could cause Podman to panic.
- Fixed a bug where `podman system reset` could fail if non-Podman containers (e.g. containers created by Buildah) were present.

### Misc
- Containers run in `podman machine` VMs now default to a PID limit of unlimited, instead of 2048.

## 4.8.3
### Security
- Fixed [GHSA-45x7-px36-x8w8](https://github.com/advisories/GHSA-45x7-px36-x8w8): CVE-2023-48795 by vendoring golang.org/x/crypto v0.17.0.

## 4.8.2
### Bugfixes
- Fixed a bug in the MacOS pkginstaller where Podman machine was using a different QEMU binary than the one installed using the installer, if it existed on the system ([#20808](https://github.com/containers/podman/issues/20808)).
- Fixed a bug on Windows (WSL) with the first-time install of user-mode networking when using the init command, as opposed to set ([#20921](https://github.com/containers/podman/issues/20921)).

### Quadlet

- Fixed a bug where currently if user specifies `podman kube play --replace`, the pod is removed on the client side, not the server side ([#20705](https://github.com/containers/podman/discussions/20705)).
- Fixed a bug where `podman machine rm -f` would cause a deadlock when running with WSL.
- Fixed `database is locked` errors with the new sqlite database backend ([#20809](https://github.com/containers/podman/issues/20809)).
- Fixed a bug where `podman-remote exec` would fail if the server API version is older than 4.8.0 ([#20821](https://github.com/containers/podman/issues/20821)).
- Fixed a bug where Podman would not run any command on systems with a symlinked $HOME ([#20872](https://github.com/containers/podman/issues/20872)).

## 4.8.0
### Features
- Podman machine now supports HyperV as a provider on Windows. This option can be set via the `CONTAINERS_MACHINE_PROVIDER` environment variable, or via containers.conf. HyperV requires Powershell to be run as Admin. Note that running WSL and HyperV machines at the same time is not supported.
- The `podman build` command now supports Containerfiles with heredoc syntax.
- The `podman login` and `podman logout` commands now support a new option, `--compat-auth-file`, which allows for editing Docker-compatible config files ([#18617](https://github.com/containers/podman/issues/18617)).
- The `podman machine init` and `podman machine set` commands now support a new option, `--usb`, which sets allows USB passthrough for the QEMU provider ([#16707](https://github.com/containers/podman/issues/16707)).
- The `--ulimit` option now supports setting -1 to indicate the maximum limit allowed for the current process ([#19319](https://github.com/containers/podman/issues/19319)).
- The `podman play kube` command now supports the `BUILDAH_ISOLATION` environment variable to change build isolation when the `--build` option is set ([#20024](https://github.com/containers/podman/issues/20024)).
- The `podman volume create` command now supports `--opt o=size=XYZ` on tmpfs file systems ([#20449](https://github.com/containers/podman/issues/20449)).
- The `podman info` command for remote calls now reports client information even if the remote connection is unreachable
- Added a new field, `privileged`, to containers.conf, which sets the defaults for the `--privileged` flag when creating, running or exec'ing into a container.
- The `podman kube play` command now supports setting DefaultMode for volumes ([#19313](https://github.com/containers/podman/issues/19313)).
- The `--opt` option to the `podman network create` command now accepts a new driver specific option, `vrf`, which assigns a VRF to the bridge interface.
- A new option `--rdt-class=COS` has been added to the `podman create` and `podman run` commands that enables assigning a container to a Class Of Service (COS). The COS has to be pre-configured based on a pseudo-filesystem created by the *resctrl* kernel driver that enables interacting with the Intel RDT CAT feature.
- The `podman kube play` command now supports a new option, `--publish-all`, which exposes all containerPorts on the host.
- The --filter option now supports `label!=`, which filters for containers without the specified label.

### Upcoming Deprecations
- We are beginning development on Podman 5.0, which will include a number of breaking changes and deprecations. We are still finalizing what will be done, but a preliminary list is below. Please note that none of these changes are present in Podman 4.8; this is a preview of upcoming changes.
- Podman 5.0 will deprecate the BoltDB database backend. Exact details on the transition to SQLite are still being decided - expect more news here soon.
- The containers.conf configuration file will be broken up into multiple separate files, ensuring that it will never be rewritten by Podman.
- Support for the CNI network backend and Cgroups V1 are being deprecated and gated by build tags. They will not be enabled in Podman builds by default.
- A variety of small breaking changes to the REST API are planned, both to improve Docker compatibility and to better support `containers.conf` settings when creating and managing containers.

### Changes
- Podman now defaults to sqlite as its database backend. For backwards compatibility, if a boltdb database already exists on the system, Podman will continue using it.
- RHEL Subscriptions from the host now flow through to quay.io/podman/* images.
- The `--help` option to the `podman push` command now shows the compression algorithm used.
- The remote Podman client’s `commit` command now shows progress messages ([#19947](https://github.com/containers/podman/issues/19947)).
- The `podman kube play` command now sets the pod hostname to the node/machine name when hostNetwork=true in k8s yaml ([#19321](https://github.com/containers/podman/issues/19321)).
- The `--tty,-t` option to the `podman exec` command now defines the TERM environment variable even if the container is not running with a terminal ([#20334](https://github.com/containers/podman/issues/20334)).
- Podman now also uses the `helper_binaries_dir` option in containers.conf to lookup the init binary (catatonit).
- Podman healthcheck events are now logged as notices.
- Podman machines no longer automatically update, preventing accidental service interruptions ([#20122](https://github.com/containers/podman/issues/20122)).
- The amount of CPUs a podman machine uses now defaults to available cores/2 ([#17066](https://github.com/containers/podman/issues/17066)).
- Podman machine now prohibits using provider names as machine names. `applehv`, `qemu`, `wsl`, and `hyperv` are no longer valid Podman machine names

### Quadlet
- Quadlet now supports the `UIDMap`, `GIDMap`, `SubUIDMap`, and `SubGIDMap` options in .container files.
- Fixed a bug where symlinks were not resolved in search paths ([#20504](https://github.com/containers/podman/issues/20504)).
- Quadlet now supports the `ReadOnlyTmpfs` option.
- The VolatileTmpfs option is now deprecated.
- Quadlet now supports systemd specifiers in User and Group keys.
- Quadlet now supports `ImageName` for .image files.
- Quadlet now supports a new option, `--force`, to the stop command.
- Quadlet now supports the `oneshot` service type for .kube files, which allows yaml files without containers.

- Fixed a bug where Quadlet would crash when specifying non key-value options ([#20104](https://github.com/containers/podman/issues/20104)).
- Quadlet now removes anonymous volumes when removing a container ([#20070](https://github.com/containers/podman/issues/20070)).
- Quadlet now supports a new unit type, `.image`.

### Bugfixes

- Fixed a bug where setting both the `--uts` and `--network` options to `host` did not fill /etc/hostname with the host's name ([#20448](https://github.com/containers/podman/issues/20448)).
- Fixed a bug where the remote Podman client’s `build` command would incorrectly parse https paths ([#20475](https://github.com/containers/podman/issues/20475)).
- Fixed a bug where running Docker Compose against a WSL podman machine would fail ([#20373](https://github.com/containers/podman/issues/20373)).

- Fixed a bug where a container with a custom user namespace and `--restart always/on-failure` would not correctly cleanup the netnsm on restart, resulting in leaked ips and network namespaces ([#18615](https://github.com/containers/podman/issues/18615)).
- Fixed a bug where remote calls to the `podman top` command would incorrectly parse options ([#19176](https://github.com/containers/podman/issues/19176)).
- Fixed a bug where the `--read-only-tmpfs` option to the `podman run` command was incorrectly handled when the `--read-only` option was set ([#20225](https://github.com/containers/podman/issues/20225)).
- Fixed a bug where creating containers in parallel may cause a deadlock if both containers attempt to use the same named volume ([#20313](https://github.com/containers/podman/issues/20313)).
- Fixed a bug where a container restarted by the Podman service would occasionally not mount its storage ([#17042](https://github.com/containers/podman/issues/17042)).
- Fixed a bug where the `--filter` option to the `podman images` command would not correctly filter ids, digests, or intermediates ([#19966](https://github.com/containers/podman/issues/19966)).
- Fixed a bug where setting the `--replace` option to the `podman run` command would print both the old and new container ID. Now, only the new container ID is printed.
- Fixed a bug where the `podman machine ls` command would show Creation time as LastUp time for machines that have never been booted. Now, new machines show `Never`, with the json value being ZeroTime.
- Fixed a bug in the `podman build` command where the default pull policy was not set to `missing` ([#20125](https://github.com/containers/podman/issues/20125)).

The active destination is not resolved with the correct priority, that is, CLI flags, env vars, ActiveService from containers.conf, RemoteURI ([#15588](https://github.com/containers/podman/issues/15588)).
- Fixed a bug where the `--env-host` option was not honoring the default from containers.conf

### API
- Fixed a bug in the Compat Image Prune endpoint where the dangling filter was set twice ([#20469](https://github.com/containers/podman/issues/20469)).
- Fixed a bug in the Compat API where attempting to connect a container to a network while the connection already exists returned a 200 status code. It now correctly returns a 500 error code.
- Fixed a bug in the Compat API where some responses would not have compatible error details if progress data had not been sent yet ([#20013](https://github.com/containers/podman/issues/20013)).
- The Libpod Pull endpoint now supports a new option, compatMode which causes the streamed JSON payload to be identical to the Compat endpoint.
- Fixed a bug in the Libpod Container Create endpoint where it would return an incorrect status code if the image was not found. The endpoint now correctly returns 404.
- The Compat Network List endpoint should see a significant performance improvement ([#20035](https://github.com/containers/podman/issues/20035)).
