# Release Notes

## 0.10.1.2
### Bugfixes
- Fixed cgroup mount for containers using systemd as init to work properly with the systemd cgroup manager

## 0.10.1.1
### Features
- Added handling for running containers as users with numeric UIDs not present in the container's /etc/passwd. This allows getpwuid() to work inside these containers.
- Added support for the REGISTRY_AUTH_FILE environment variable, which specifies the location of credentials for registry login. This is supported by the `push`, `pull`, `login`, `logout`, `runlabel`, and `search` commands

### Bugfixes
- Fixed handling for image volumes which are mounted on symlinks. The links are now resolved within the container, not on the host
- Fixed mounts for containers that use systemd as init to properly include all mounts required by systemd to function

### Misc
- Updated vendored version of Buildah used to power `podman build`

## 0.10.1
### Features
- Added the `podman container checkpoint` and `podman container restore` commands to checkpoint and restore containers
- Added the `podman container runlabel` command to run containers based on commands contained in their images
- Added the `podman create --ip` and `podman run --ip` flags to allow setting static IPs for containers
- Added the `podman kill --all` flag to send a signal to all running containers

### Bugfixes
- Fixed Podman cleanup processes for detached containers to properly print debug information when `--syslog` flag is specified
- Fixed manpages for `podman create` and `podman run` to document existing `--net` flag as an alias for `--network`
- Fixed issues with rootless Podman where specifying a single user mapping container was causing all Podman commands to hang
- Fixed an issue with rootless Podman not properly detecting when user namespaces were not enabled
- Fixed an issue where Podman user namespaces were not preserving file capabilities
- Fixed an issue where `resolv.conf` in container would unconditionally forward nameservers into the container, even localhost
- Fixed containers to release resources in the OCI runtime immediately after exiting, improving compatability with Kata containers
- Fixed OCI runtime handling to fix several issues when using gVisor as an OCI runtime
- Fixed SELinux relabel errors when starting containers after a system restart
- Fixed a crash when initializing hooks on containers running systemd as init
- Fixed an SELinux labelling issue with privileged containers
- Fixed rootless Podman to raise better errors when using CGroup resource limits, which are not currently compatible with rootless
- Fixed a crash when runc was used as the OCI runtime for containers running systemd as init
- Fixed SELinux labelling for containers run with `--security-opt label=disable` to assign the correct label

### Misc
- Changed flag ordering on all Podman commands to ensure flags are alphabetized
- Changed `podman stop` to work in parallel when multiple containers are specified, greatly speeding up stop for containers that do not stop after SIGINT
- Updated vendored version of Buildah used to power `podman build`
- Added version of vendored Buildah to `podman info` to better debug issues

## 0.9.3.1
### Bugfixes
- Fixed a critical issue where SELinux contexts set on tmpfs volumes were causing runc crashes

## 0.9.3
### Features
- Added a flag to `libpod.conf`, `label`, to globally enable/disable SELinux labelling for libpod
- Added `--mount` flag to `podman create` and `podman run` as a new, more explicit way of specifying volume mounts

### Bugfixes
- Fixed a crash during container creation when an image had no names
- Fixed default rootfs mount propagation to for containers to match Docker
- Fixed permissions of `/proc` in containers
- Fixed permissions of some default bind mounts (for example, `/etc/hosts`) in read-only containers
- Fixed `/dev/shm` in `--ipc=container` and `--ipc=host` containers to use the correct SHM
- Fixed rootless Podman to properly join the namespaces of other containers
- Fixed the output of `podman diff` to not display some default changes that will not be committed
- Fixed rootless to better handle cases where insufficient UIDs/GIDs are mapped into the container

## 0.9.2.1
### Bugfixes
- Updated Buildah dependency to fix several bugs in `podman build`

### Misc
- Small performance improvement in image handling code to not recalculate digests

## 0.9.2
### Features
- Added `--interval` flag to `podman wait` to determine the interval between checks for container status
- Added a switch in `libpod.conf` to disable reserving ports for running containers. This lowers the safety of port allocations, but can significantly reduce memory usage.
- Added ability to search all the contents of a registry if no image name is specified when using `podman search`

### Bugfixes
- Further fixes for sharing of UTS namespaces within pods
- Fixed a deadlock in containers/storage that could be caused by numerous parallel Podman processes.
- Fixed Podman running into open file limits when many ports are forwarded
- Fixed default mount propagation on volume mounts
- Fixed default mounts under /dev remaining if /dev is bind-mounted into the container
- Fixed rootless `podman create` with no command specified throwing an error

### Misc
- Added `podman rm --volumes` flag for compatability with Docker. As Podman does not presently support named volumes, this does nothing for now, but provides improved compatability with the Docker command line.
- Improved error messages from `podman pull`

### Compatability
- Podman is no longer being built by default with support for the Devicemapper storage driver. If you are using this storage driver, you should investigate switching to overlayfs.

## 0.9.1.1
### Bugfixes
- Added support for configuring iptables and firewalld firewalls to allow container traffic. This should resolve numerous issues with network access in containers.

### Note
It is recommended that you restart your system firewall after installing this release to clear any firewall rules created by older Podman versions. If port forwarding to containers does not work, it is recommended that you restart your system.

## 0.9.1
### Features
- Added initial support for the `podman pod` command as non-root

### Bugfixes
- Fixed regression where invalid Podman commands would still cause a clean exit
- Fixed `podman rmi --all` to not error if no images are present on the system
- Fixed parsing of container logs with `podman logs` to properly handle CRI logging, fixing some issues with blank lines in logs
- Fixed a bug creating pod cgroups using the systemd cgroup driver with systemd versions 239 and higher
- Fixed handling of volume mounts that overlapped with default container mounts (for example, `podman run -v /dev/:/dev`)
- Fixed sharing of UTS namespace in pods

### Misc
- Added additional debug information when pulling images if `--log-level=debug` is specified
- `podman build` now defaults to caching intermediate layers while building

## 0.8.5
### Features
- Added the ability to add a multipart entrypoint with `podman run --entrypoint`
- Improved help text when invalid commands are specified
- Greatly improved support for containers which use systemd as init

### Bugfixes
- Fixed several bugs with rootless `podman exec`
- Fixed rootless `podman` with a symlinked storage directory crashing
- Fixed bug with `podman ps` and multiple filters where the interface did not match Docker
- Fixed handling of `resolv.conf` on the host to handle symlinks
- Increased open file descriptor and process limits to match Docker and Buildah
- Fixed `podman run -h` to specify the container's hostname (as it does in Docker) instead of printing help text
- Fixed a bug with image shortname handling where repositories were incorrectly being treated as registries
- Fixed a bug where `podman wait` was busywaiting and consuming large amounts of CPU

## 0.8.4
### Features
- Added the `podman pod top` command
- Added the ability to easily share namespaces within a pod
- Added a pod statistics endpoint to the Varlink API
- Added information on container capabilities to the output of `podman inspect`

### Bugfixes
- Fixed a bug with the --device flag in `podman run` and `podman create`
- Fixed `podman pod stats` to accept partial pod IDs and pod names
- Fixed a bug with OCI hooks handling `ALWAYS` matches
- Fixed a bug with privileged rootless containers with `--net=host` set
- Fixed a bug where `podman exec --user` would not work with usernames, only numeric IDs
- Fixed a bug where Podman was forwarding both TCP and UDP ports to containers when protocol was not specified
- Fixed issues with Apparmor in rootless containers
- Fixed an issue with database encoding causing some containers created by Podman versions 0.8.1 and below to be unusable.

### Compatability:
We switched JSON encoding/decoding to a new library for this release to address a compatability issue introduced by v0.8.2.
However, this may cause issues with containers created in 0.8.2 and 0.8.3 with custom DNS servers.
