From cd7c2f1de7d9e418bb554047d714dd7cacc020ff Mon Sep 17 00:00:00 2001 From: Simon McVittie Date: Tue, 3 May 2022 15:16:11 +0100 Subject: [PATCH] Switch versioning scheme to be the same as GLib and Flatpak For stable releases, this gives us the ability to make bugfix-only point releases such as 2.24.1 if we want to, and distinguish between them programmatically. For example, this ability could have been useful after 2.0.16 to fix Xwayland regressions, and after 2.0.18 to fix event loop regressions. For development releases, this gives us the ability to make multiple prereleases during the same feature cycle, and distinguish between them programmatically. For example, this would have been useful during 2.0.22 development, which went through three prereleases before reaching the final release.
