Apologies if I'm missing something obvious, but I can't find a set of release notes for recent versions. I rtfmed a bit and found links on Gemini to a road map and lots of good information about current development & fixes. What I'm looking for is feature summaries, though, ideally version by version. The purpose is to review what's added along the way to decide when & why to upgrade and to which specific version. (Some of us like to trail the bleeding edge a bit to avoid problems we lack the skills to fix.)

Can anyone point out something like that? Search results just come back to forum posts that were relevant for particular problems but not helpful for bigger-picture stuff.
