Sectors mode: changed Alt-key handling. Now it only enables "snap to grid increment" mode.
Things mode: "snap to grid increment" mode now works in this mode.
Updated documentation.
Visual mode: real floor was colored by 3d floor's color even when it was below real floor.
Action Browser form: keyboard focus is now set to Filter text box by default.
"Texture 'XXX' is double defined in resource 'YYY'." warning is no longer displayed if a TEXTURE1/2 texture contains a patch with the same name as the texture.

BCC script compiler (https://github.com/wormt/bcc/) is now bundled with GZDB.
Main Form, "File" menu: only existing files are now added to the "recent files" list.

Sectors Mode: "Flip Linedefs" action is now available form this mode, and it will also try to align linedefs, so their front (or back) point towards the same sector.

Textures Browser: added support for displaying long texture names.
Errors list is now cleared when reloading resources.
Visual mode: added basic support for sector slopes (no UI for that feature yet).
Changed "Raise Floor by 8 mp" and "Lower Floor by 8 mp" default shortcuts to "Ctrl-Alt-ScrollUp/ScrollDown", because they used the same keys as "Increase Brightness" and "Decrease Brightness" actions.
Snippets: changed token syntax from $XX to [XX]
[LB] (Line Break) marker can now be used in snippets.
Game Configurations: added "enabledbydefault" parameter. When set to true, a game configuration will be available by default (e.g. when an user starts the editor for the first time).

ScintillaControl.GetLine() was retrieving incorrect line.
Randomize mode: randomized pitch, roll and scale can now be applied to things.

Model rendering, UDMF: scale was applied incorrectly to models with pitch or roll.
Updated documentation.
