Audacity 2.4.2 changelog:
- The main change since 2.4.1 is that we have upgraded the wxWidgets library that Audacity uses from 3.1.1 (with patches by us) to 3.1.3 (with patches by us). We wanted to do this as a release in its own right, before we start on a longer and more complex release.
- If you’re using Audacity 2.4.2 on Linux, do use the right wxWidgets library. We’ve in the past had a lot of reports of problems on Linux that turned out in the end to be because some distributions were using system wxWidgets (3.0.0) with Audacity.
- We’ve fixed 41 bugs since 2.4.1. The exact number of bugs fixed depends on how you count, but anyway, it’s a worthwhile number of fixes.
- There is one new small feature. In the Tools menu there is now a ‘Reset Configuration’ menu item. When you click on it, it resets most of the configuration back to defaults.
