The only thing I know with half of those features that's discontinued is the old Darkroom app but that doesn't tackle some of the bigger compatibilities. Source: about 2 years ago

Not sure if this is applicable, but if you're using Word or Scrivener or something, you may want to switch to a plaintext editor like Dark Room or Typora--something that won't underline your spelling and grammar mistakes.

It makes no sense to use an unstable version of that upstream, as in its development releases it literally breaks on every patch level release. It also makes no sense to start packaging a custom version of wxgtk just for audacity (the overhead required is just not worth it). Source: over 2 years ago
