Currently this section mentions:

Another minor issue is that the interface doesn't currently offer links to commit logs between each release.

However this is no longer the case. Projects that are making use of Github Releases as their changelog now have a feature for this. Each release includes a Compare dropdown that allows viewing the commits in between tags, the files that changed, and any comments left on the commits.

For example: https://github.com/crystal-lang/crystal/releases/tag/0.34.0 and the related diff crystal-lang/crystal@0.33.0...0.34.0.
