Is this needed to be in the user facing documentation? I think mainly because it's not an opt-in/opt-out for the user?

I decided to put the full changelog in one spot in the docs, for all users and CSCS staff alike.

- Add `--json` option to `image ls` and `image find`.
- add `--format` flag to uenv status.

### Improvements

- force unsquashfs to use a single thread when unpacking meta data.
- reimplement squashfs-mount in the main repository.
- improve file name completion in bash.

### Fixes

- Turn some CLI flags into options, so that they can be set with or without `=`. e.g. `uenv --repo=$HOME/uenv` or `uenv --repo $HOME/uenv`.
- Only use the meta data path adjacent to a uenv image if it contains an env.json file.
- `image push` was not pushing the correct meta data path.
- a bug where the `--only-meta` flag was ignored on `image pull`.
- add hints to error message when uenv is not found.
