I'm staring at the changelog for a few games which have updated. Aside from the lack of update tracking on GOG.com, and the lack of an automatic changelog log, sometimes these build changes are extra inscrutable.

Fisher-Price Unix requiring signed binaries, fair enough; Papers, Please. Parkitect's update logs stop at 2024, so let's take a squint at GOGDB. There's Version 1.11, Version 1.11a, Version 1.11a2.2, and so on. Fine, incremental patches.

But I clicked on the update bubbles on the other games, and now I frankly don't recall which ones they are. I suppose what I'm saying is that the Library is missing a sorting order, along the lines of "Recently Updated".

Game pages should present a list of updates, that you can click on to get further info.
Steam have something somewhat like that, if a bit bloated generally.
