 - Create a new branch `extend-tests` from `main` and work in this branch.
 - To submit, open a PR from `extend-tests` to `main` in your own repository. Then paste a link to this PR in a new issue in the original repository. Use `[GITLAB-USERNAME] Boost test exercise` as title of the issue.

 - Extend the automation with a [build matrix](https://docs.github.com/en/actions/using-jobs/using-a-build-matrix-for-your-jobs). Test whether your code builds in Debug and in Release mode, and with the gcc and the clang compiler. Make use of CMake variables to modify these parameters.
+- Implement more tests.
 
 ## Hints and Remarks
 
 - When importing a project on GitHub, it could be that by default actions are disabled. You can enable them via `Settings -> Actions -> General -> Allow all actions`.
 - Be careful: the style job should not format the code, but rather report whether the code was formatted correctly or not. There are different ways how to do this. You could use the option `--dry-run`, but then you still need to interpret warnings as errors with `-Werror`. Or you could format inplace (`-i`) and use `git diff`.
-- Try to use the build from the build job for the tests in the test job by uploading and downloading the build as an artifact. Problem is that this way file permissions are not preserved. You can work around this problem, by archiving. See [the official workaround](https://github.com/actions/upload-artifact#maintaining-file-permissions-and-case-sensitive-files).
+- Try to use the build from the build job for the tests in the test job by uploading and downloading the build as an artifact. Previously, there was an issue with file permissions, where archiving was [a known workaround](https://github.com/actions/upload-artifact/tree/v3.2.1?tab=readme-ov-file#maintaining-file-permissions-and-case-sensitive-files). This should no longer be a problem.
