Added Properties > Speed > Pitch Compensation for automatic pitch correction for speed changes > 0.1x.
Added a Replace command to Timeline clip menu including blank regions with shortcut <kbd>R</kbd>.
Properties > Reverse now automatically replaces a selected clip on the timeline (or in Source player if using that).
Added 15 second handles when using Properties > Reverse on a timeline clip. Handles are extra footage before the in point or after the out point. This makes it easier to adjust edits or add transitions around reversed clips.
Added Properties > Duration > Timeline to show (not editable) the duration of a timeline clip.
Added a Corner Pin video filter (thanks to @sauron in the forum for the initial effort).
Added a Properties > Convert button to make Convert to Edit-friendly in the menu more convenient (kept in the menu for now because a number of support tips reference it).
Properties > Convert now automatically replaces respective clips in Source and Timeline and adds its clip to the Playlist.

Changes

Changed Export > Video > Parallel processing to default to OFF but also now it save the state between export jobs and app session.
Added support for FFmpeg sample_fmt option to Export > Other.
Automatically disable parallel processing on add-on bigsh0t (360) video filters.
Stop adding title="Anonymous Submission" to MLT XML.
Increased the priority of background jobs a little on macOS and Linux (still less than normal).
Added 448k to Export > Audio > Bitrate.
Added automatically scroll the Timeline when you double-clock a clip to select-and-seek.
Updated the mouse wheel behavior in Keyframes to match the changes to Timeline in version 20.02.
Added an option to place an icon on the Desktop to the Windows installer.
Add a cursor to the Audio Waveform scope.
Removed Export > Stream as it is not supportable in its current state.
Changed shortcuts <kbd>C</kbd> and <kbd>Ctrl</kbd>+<kbd>C</kbd> to work with the clip under the playhead of the current track if no clip is selected. This makes it behave similar to other editing shortcuts.
Changed the keyboard modifier for skim to <kbd>Shift</kbd>+<kbd>Alt</kbd>. This prevents <kbd>Shift</kbd> (previous modifier) when selecting multiple clips from changing playhead position. NOTE: On macOS, in order to scroll Timeline or Keyframes horizontally with a mouse wheel (not Magic Mouse or track pad), you must also use one of the following:
- <kbd>Control</kbd>
- <kbd>Control</kbd>+<kbd>Option</kbd>
- <kbd>Control</kbd>+<kbd>Command</kbd>
- <kbd>Option</kbd>+<kbd>Command</kbd>
Changed the Matrix parameter of the Dither video filter to be a drop-down combo box without keyframes support.
Changed Alpha operation > Write On Clear to Overwrite on some video filters to make them more clear:
- Mask: Simple Shape
- Chroma Key: Advanced
