feat: release for version 2.4.0 of the spec

[smoya]

This PR is created upfront to reflect on a daily basis what things are included in the release.

Also, the reason to create this PR a long time before the release is to enable automation (bot keeps upstream branches always up to date with master, see this action) that we have in place to regularly update the release branch with whatever is changed in the master branch. So nobody has to do it manually.

For the record: This branch had conflicts because we did squash when merging instead of simple (and no fast-forward) merge on #772. That's the reason we also see a lot of content on this PR that is already in master branch, because the merge commit is lost, so there is a new commit with no relation with parents in master branch, even though the content is the same. Related Stack Overflow: https://stackoverflow.com/questions/54636294/github-pr-squash-causes-erroneous-merge-conflicts.
I will open an issue after the release.
