It’s always nice to see a new release of the free workhorse audio-editor Audacity, now in 2.3.3 (22nd Nov 2019). The developers have mostly been bug-stomping, but “leading silence is now preserved in exports” and the .M4A export gets new quality presets.
Also open source and free, the excellent new painting and inking software Krita 4.2.8, with faster loading and even more work on the speed and autoprecision of the brush presets.
