+If you wanted to compile a recent version of Mixxx 2.3 beta or 2.4 yourself, you may have already noticed that we removed our old and rusty [SCons](https://scons.org/) setup in favor of [CMake](https://cmake.org/).
+
+[A few months ago]({% url "/news/2020-07-15-new-in-2-3-cmake.html" %}) we said that we were planning to ship Mixxx 2.3 with both SCons and CMake configurations (the latter would be considered "experimental").
+However, that turned out to be impractical.

+
+All of core developers started using CMake as their primary build system since [initial support for it was added](https://github.com/mixxxdj/mixxx/pull/2280) more than a year ago.
+Our build servers that we use to compile and test Mixxx during development have also been switched to CMake.
+That means that the SCons build received a lot less testing compared to the CMake build.
+
+Due to the maintenance burden of keeping an additional build system and some problems with our SCons configuration that popped up recently, we decided to [remove SCons](https://github.com/mixxxdj/mixxx/pull/2777) and use CMake exclusively for the upcoming 2.3 release.
+That should free some resources and will allow us to work on more important issues than keeping our SCons build alive.
