Visual mode: thing brightness calculation when a thing is affected by floor glow is now much closer to GZDoom one.
Linedef edit window, UDMF: added "Reset front/back brightness" buttons.
Sector edit window, UDMF: added "Reset ceiling/floor brightness" buttons.
Internal, Visual mode, Things mode: persistent event lines are now updated only when map objects are changed instead of doing it on every display redraw.
Internal: improved Dictionary lookup times when using map objects and textures as keys.
Internal: added "Release + Profiler" solution configuration.
Updated ZDoom_ACS.cfg (Warp).
Removed, Texture Browser: removed "Show image sizes" checkbox. "Show texture and flat sizes in browsers" preferences setting is now used instead.

Fixed, Things mode: highlight range for sizeless things (things with "fixedsize" game configuration property) was calculated incorrectly.
Fixed: fixed a crash when opening Script Editor after using "Open map in current wad" command to switch to UDMF map with SCRIPTS lump when current script configuration was not saved in the wad's .dbs file.
Fixed: map closing events were not triggered when using "Open map in current wad" command, which could potentially result in plugin crashes/incorrect behavior.

Internal: added "Debug + Profiler" solution configuration, added 2 profiling methods to DebugConsole.
Internal: rewrote MainForm.DisplayStatus() / StatusInfo to handle selection info in a more structured way.
Fixed, internal: some destructors could potentially be executed more than once potentially leading to exceptions. Other destructors were not called at all.
Updated ZDoom_DECORATE.cfg.
Tag Range plugin: tags can be set in relative mode (when this mode is enabled, generated values are added to existing tags instead of replacing them).

Texture size labels were displayed incorrectly in some cases.
Rewritten VerticesMode.DeleteItem() once again...

Vertex Edit form: ceiling and floor vertex offsets can now be cleared.

Changed background color of Sector Edit form.
Vertex' ZCeiling and ZFloor properties are now managed internally.
