## Audacity 3.4.2

There's a really awful playback issue on my machine that causes delays of up to several seconds when playing back audio.

## Opening a 3.4.x project in 3.3.x

For some reason, when opening a project saved in Audacity 3.4.2 in 3.3.3, all of the mono audio tracks were converted tot left channel stereo. The fix was:

* pick a track and Make Stereo Track. This will take this track and the track below and make them stereo.
* Split Stereo to Mono then takes both tracks and marks the mono again.
