If you want to do release notes, these are quite the goal to copy. Explain the issue, what the developer did to solve it, and what is now enabled. Probably the best I’ve ever read and I’ve not used dolphin in a decade, but I still read each one.

Plus on an open source project it may be a great way to attract more developers and document how the software works internally which may pay for itself.
