The releases page notes e.g. https://matrix-manuals.squiz.net/releases/5.3/5.3.4.1 provide a useful summary of the enhancements and bugfixes, but searching through them for what's changed can be a bit of a manual task.
Would a development be possible where we could put in two version numbers, and have a list generated of all the enhancements and fixes that would be added from an upgrade?
