 ### Changes
 - Podman will now retry pulling an image 3 times if a pull fails due to network errors.
 - The `podman exec` command would previously print error messages (e.g. `exec session exited with non-zero exit code -1`) when the command run exited with a non-0 exit code. It no longer does this. The `podman exec` command will still exit with the same exit code as the command run in the container did.

 - Fixed a bug where the `podman wait` command would only accept a single argument.
+- Fixed a bug where the parsing of the `--volumes-from` option to `podman run` and `podman create` was broken, making it impossible to use multiple mount options at the same time ([#7701](https://github.com/containers/podman/issues/7701)).
+- Fixed a bug where the `podman exec` command would not join executed processes to the container's supplemental groups if the container was started with both the `--user` and `--group-add` options.
+- Fixed a bug where the `--iidfile` option to `podman-remote build` was nonfunctional.
