Audacity 3.0.4 changelog:
This is a hotfix release that fixes a bug with envelope points, which could multiply uncontrollably and cause Audacity to crash. In particular:
- #1476: Envelope points are multiplied when using Filter Curve EQ or Graphic EQ
- #1477: Filter Curve EQ will crash if there is an envelope point outside of the selection
This fix re-introduces an earlier, but way less destructive bug:
- bugzilla 208 / #1500: Some effects delete Envelope Control Points, or do not move them when timeline changes
Other than that, this release is identical to Version 3.0.3.
