Consider creating a "What's new" section that highlights in a "librarian friendly" way the new features, enhancements, and things fixed in a release - each item would eventually link to the updated section(s) in the documentation. This could make it easier for Koha Community members to identify what's new in a release, and save some of the work that support providers do each release highlighting the changes (or at least create a good starting point!). It could also be supported by a presentation (for use at events) and a video.
The idea for this was influenced by these presentations: 1. Best Practices for Creating & Managing Release Notes (Part One): https://heretto.com/best-practices-for-creating-and-managing-release-notes-part-one/ (and also https://heretto.com/release-notes-webinar-part-1/) 2. Webinar: Release Notes Part 2 https://heretto.com/release-notes-part-2/
A related idea Bug 22890 - Add a chronological changelog. While not exactly the same there are some similarities.
