Raw Blame History

This is a list of major changes in SDL's version history.
---------------------------------------------------------------------------
2.24.0:
---------------------------------------------------------------------------
General:
* New version numbering scheme, similar to GLib and Flatpak.
* An even number in the minor version (second component) indicates
a production-ready stable release such as 2.24.0, which would have
been 2.0.24 under the old system.
* The patchlevel (micro version, third component) indicates a
bugfix-only update: for example, 2.24.1 would be a bugfix-only
release to fix bugs in 2.24.0, without adding new features.
* An odd number in the minor version indicates a prerelease such
as 2.23.0. Stable distributions should not use these prereleases.
* The patchlevel indicates successive prereleases, for example
2.23.1 and 2.23.2 would be prereleases during development of
the SDL 2.24.0 stable release.
