Fixed, Map conversion: game mode flags were ignored when converting from Doom map format to UDMF.
Fixed, Edit Selection mode: when "Drag selection automatically on paste" setting was enabled, it was possible to start rotating/scaling map elements instead of dragging them after pasting.
Fixed, MAPINFO parser: in some cases the parser was skipping the whole file instead of current map block while parsing classic map definition.
Fixed, Visual mode: classic sky model had incorrect rotation.
Updated skybox model to better match GZDoom's skybox. Also the sky texture was flipped horizontally.
Fixed, Visual mode: "Select with the same texture" action is now able to select sidedef parts only visible because of slopes.
Fixed, Visual mode: skybox texture was not updated after using "Open map in current wad" action.
Fixed, Visual mode: in some cases Visual camera was placed below sector's floor when "Sync camera position between 2D and 3D modes" setting was enabled.

Fixed, command line arguments: fixed a crash when loading a map from a wad with existing .dbs file.
Fixed, Visual mode: aspect ratio was not updated when render area was resized.
Fixed, Visual mode: vertex handles were disappearing after using Reload Resources (F8) action.
Changed, internal: removed most of the fixed pipeline rendering code. The editor can no longer be used on a video card without Shader Model 2.0 support.

Changed, Sector drawing: default sector height is now used when the nearest sector's height is <= 0.
Added "Toggle sky rendering" action and toolbar button.
Added, MAPINFO parser: the editor now recognizes map number from classic map definition format. Hexen MAPINFO is now properly parsed.
Added, MAPINFO support: if current map definition contains map name as a text string, it will be shown in the editor's header.
Changed: "Toggle dynamic lights rendering" now toggles between "Don't show dynamic lights" and "Show dynamic lights" when used in Classic modes.
Changed, Things mode: lowered the opacity of dynamic light radii.
Changed, (G)ZDoom text parsers: empty include files now trigger a warning instead of an error and no longer abort parsing.
Fixed, Game configurations: moved Stalagmite:5050 thing to Doom block (so the editor no longer tries to load it for non-Doom game configurations).
Fixed(?), Visual mode: probably fixed a hard-to-trigger exception when sorting translucent geometry.
Fixed, Visual mode: floor glow effect was incorrectly applied to walls (was broken in R2452).
Internal: restructured most of MAPINFO and GLDEFS parsers. Should be more maintainable now.
Updated ZDoom ACC.
Updated zdbsp to 1.19.
Updated documentation.
Fixed, Map Analysis mode: fixed a crash when trying to dissolve an invalid sector when one of it's linedefs referenced it on the both sides.

Fixed, Script Editor: in some cases incorrect error line number was shown.
Fixed, Text lump parsers: fixed a crash when trying to get a filename from a quoted string with missing closing quote.
Fixed, Text lump parsers: in several cases parsing errors were ignored by overlaying data structures.
Fixed: in some cases Thing Filter thing flags were cleared when switching game configurations in the "Game Configurations" window.
Changed, PK3 reader: loading of files with invalid path chars is now skipped instead of skipping loading of the whole resource. Also more helpful warning message is now displayed.
Updated SharpCompress library to v.0.11.2.0.
Internal, Renderer2D.RenderArrows(): only visible lines are now rendered.
Internal, API: renamed public Line3D properties: v1 to Start, v2 to End, color to Color, renderarrowhead to RenderArrowhead.
Updated, Visual mode, "Raise Floor/Ceiling/Thing to adjacent Sector/Thing" / "Lower Floor/Ceiling/Thing to adjacent Sector/Thing" actions: sectors across targeted sectors are now taken into account when determining target height.
Updated, Visual mode, "Raise Floor/Ceiling/Thing to adjacent Sector/Thing" / "Lower Floor/Ceiling/Thing to adjacent Sector/Thing" actions: the actions can now stack things on top of other things when their bounding boxes intersect.
Internal: cosmetic changes to shader update logic.
Internal: thing bounding box is now used when adding a thing to VisualBlockMap.
Changed, Image formats: GIF images will no longer be loaded, because (G)ZDoom doesn't support them.

Updated ZDoom_ACS.cfg.
Updated ZDoom ACC.

Changed: when an external acs file is marked as #library, it will be saved as [library name].o alongside [filename].acs.
Fixed: files opened using "Open File" command were immediately flagged as changed.
Fixed: Script Editor was unable to navigate to error location after clicking on the error description when the error was in include file.
Updated ZDoom ACC.
Fixed, Script Editor, cosmetic: we should not show error line number when we don't have one.
ZDoom acc.exe: several error types now output more detailed info.
Fixed, Visual mode: UDMF thing alpha property was applied only when UDMF renderstyle property was also set (should also be applied when renderstyle property is set in the DECORATE actor definition).
Game configurations, ZDoom family: Pistol and Gold Wand actors now use internal sprites.
Updated ZDoom ACC and ZDoom_ACS.cfg (PickActor flags).
Fixed, Visual mode: glow effect was not updated when changing sector textures using the "Select Texture" action.
Browse Textures/Flats window: when textures list is focused, you can now start typing to change the Filter.
MODELDEF support: model frame number / frame name are now taken into account when loading MD2 models.

Game Configurations: changed "Pistol" display sprite to the one provided with (G)ZDoom.
Changed, ACC compiler: when building includes list, the compiler no longer tries to find/copy include files defined in current script configuration (previously it was hardcoded to skip "zcommon.acs" and "common.acs" only).
Fixed, Visual mode: things with Additive RenderStyle were rendered as additive only when their alpha was less than 1.0.
