- Added option to enable additive paint selecting without holding shift independently from regular additive selecting

- The missing textures checker now finds missing upper/lower textures on 3D floors when the appropriate flags of the Sector_Set3dFloor special are used. Fixes #269

- Textures will now wrap correctly in visual mode when the flag of the Line_SetIdentification special is set in Hexen format. Fixes #271

- Fixed a bug where the unknown texture error checker didn't report unknown textures on sidedefs that were never seen. Fixed #270

- Fixed a bug where textures for internal model skin names did not load when "Path" was specified in MODELDEF

- Fixed a problem where model textures were not loaded from the textures directory or from TEXTUREx definitions. Fixes #173 and #226

- Improved performance of the texture browser. This should significantly reduce the times it takes to open the texture browser when using large texture sets

- Fixed a bug where moving the mouse outside the window could crash when pasting a selection while having auto dragging enabled. Fixes #110.

- Fixed a freeze in the Tag Range plug-in when using the "relative" and "skip used tags" options. Fixes #125.

- Fixed an issue where the current editing mode was not re-initialized properly when opening a map from current WAD

- Test map from current mouse position now works properly in Hexen/UDMF maps with multiple player starts. Also works in maps without a valid player start now. Fixes #263.

- Improved support for auto aligning scaled textures

3D floors are now updated in real time in visual mode when their control sector is sloped through the line slope action. Fixes #250.

* Adding check for missing activations on lines that have an activation-requiring action

* Adding skip check if the map isn't UDMF

* Oops, typo in name of check

Added: string/float user variables, //$UserDefaultValue <value> for specifying default user variable value

Fixed: GZDB wouldn't load plugins on certain paranoid systems due to plugin DLL's being "remote" and unsigned (reported by Lorenzo)

Added .iwad, .ipk3, .ipk7 extensions to recognized list (reported by someone somewhere some time ago...)

Fixed null reference in visual mode when trying to render a thing without a sector (reported by Ozymandias81)
