Release Checklist 2.4.0

Mixxx 2.4.0 Release Checklist

This process is followed when it is time for a release (after betas and release candidates).

1. Take care of the known regressions https://github.com/mixxxdj/mixxx/labels/regression Fix and merge them, or document them in the CHANGELOG? Release Notes.
2. Release 2.3.6
3. "Close" the 2.3 branch by target all 2.3 PRs to 2.4
4. Update translations
   1. Push and pull translations for Mixxx as described here: Internationalization
5. Take release screenshots for press page and blog post.
   1. Deere, LateNight, Shade, Tango
   2. Load up samplers, preview deck, etc.
   3. Make all the screenshots roughly uniform (same view, same tracks loaded, etc.)
   4. Take screenshots of the Mixxx window itself, not with your cluttered desktop in the background.
      1. macOS can produce particularly pretty drop-shadow screenshots with Shift-Command-4 followed by the spacebar, then click the window to screenshot.
6. Send out pre-announcement to the DJ press (to ensure, that they have enough time to write articles and record review videos)
