 **New Features and Improvements**
-* Add "Fast Line-of-Sight Calculation" option, a faster blockmap-based algorithm from Doom 1.2 (also Heretic).
-* Add "Invulnerability Effect" option to override the MBF "sky fix", and provide a "Gray" colormap that is easier on the eyes.
+* Add "Crossfade" and "Fizzle" screen wipe options.
+* Improve simultaneous mouse and gamepad input.
+* Don't apply threshold to raw mouse input. Fix "sluggish" mouse movement at high frame rates.
+* Display "off" when mouse acceleration is disabled.
+* Add support for the `DBIGFONT' lump. Improve large font menus in some PWADs (Eviternity I-II, Dimension of the Boomed).
+* "-complevel" parameter takes precedence over the `COMPLVL` lump.
+* Draw the IDRATE widget exclusively.
+* Do not increase the default gain of the FluidSynth MIDI player to avoid distortion. This can be set using the `mus_gain` config parameter.
+* Open menu with mouse click during demo playback.
+* Disable "Classic BFG" in strict mode.
+* Print warning instead of error out with empty PWAD (fix NULL.WAD in eternal.zip).
 
 **Bug Fixes**
-* Apply deadzone to gamepad for strict mode check.
-* Prevent turning on first tic of an SR50.
-* Render linedef texture instead of sky if flat is missing.
-* Make light levels independent of screen size.
-* Fix menu tab centering.
+* Fix "Monsters can see through walls" bug with "Fast Line-of-Sight Calculation" option enabled. Taken from ZDoom.
+* Revert changes to mouse look calculations (fix "garbage" pixels on some sprites).
+* Print date and time in the Load/Save Game menus in the current locale.
+* Fix initialisation with invalid `video_display` setting (thanks to @joanbm).
+* Using "-strict" always disables related menu items.
+* Fix "Invulnerability Effect" option affecting beta light amplifier.
