Changes

Improved behavior when press enter/return in the current position timecode field.
Made it is easier to choose opaque black in the color chooser dialogs.
Changed numeric fields in Size, Position & Rotate and Text: Rich to require <kbd>Enter</kbd>, <kbd>Tab</kbd>, or click outside (de-focus) to apply the change. This prevents the filter going to weird or undesired sizes or positions as you enter values.
Changed Text: Rich default size and postion to have a 10% margin inside the frame.

New

Added a warning dialog when the computer is getting low on available memory.
Added Properties > menu > Set Equirectangular....
Added a Start Offset time parameter and Apply transform option to the 360: Stabilize video filter.
Added a Show Grid option to the 360: Transform video filter as a visual aid.
Added a dialog to confirm trying to add or paste filters to Timeline > Output.
Added Move Up, Move Down, and Deselect buttons to Filters.
Added command line option --QT_SCALE_FACTOR_ROUNDING_POLICY that accepts values: Round, Ceil, Floor, RoundPreferFloor, PassThrough. The default is Round except on Windows where it is RoundPreferFloor, which makes it treat 150% like 100% to reduce the UI text size.
