Fixes

- Add additional global location of rulesets for default installation from PyPI

Minor

- Run tests in upstream on the Testing Farm via Packit
- Few code-style changes suggested by Sourcery

Fixes

- The global location of rulesests is now correctly found.

- Badly done release (version not updated everywhere).
- Replaced by `0.5.2`.

Features

- Result can be converted to xunit xml file. (You can use `--xunit` CLI option to set the file we save the xunit output to.)
- Support for scanning images in OCI format.

Breaking changes

- Minimal supported version of Python has been raised to 3.6.
- Support for images in ostree format has been removed because Fedora 30 was the latest one
which had support for ostree in Skopeo. (Replaced by newly added support for OCI format.)

Minor

- The timeout overwriting now works as expected.

Features

- Create a new check which makes sure that certain labels are overridden in
layered images.
- Certain remote API calls are now being retried - this should help in environments where network is unreliable.

Breaking changes

- Python 2 is now completely unsupported.

Minor

- A bunch of usability issues: when things go wrong, colin should not
produce more helpful error messages and logs.

Fixes

- Fix metadata checks (ENV, USER) for podman images.
- Fix Fedora packaging. (Conu was temporarily removed from requirements.)
- Documentation updated.

Breaking changes

- Remove support for Python 2.
