Use the .net framework image loaders if they work. They do for the sane formats (PNG and JPEG) and they are faster, too.
Enable usage of multiple threads for resource loading now that it no longer crashes
Remove thread priority settings (this is not the right way to do it)
Stop brain dead busy looping and use Monitor.Wait + Monitor.Pulse
Only call Control.Invoke if its a worker thread calling RunOnUIThread
Add the code for running multiple background threads (unfortunately blocked by DevIL apparently not being thread safe, gg!)
Fixed, Textures Browser: only name filtering is now applied to folder-type image items, filtering is never applied to "go to parent folder" image items.

Updated, Game configurations, UDMF: added several missing Thing renderstyles.
Updated, Script editor: script editor was unable to show error location after double-clicking on it in the Warnings and Errors window when said location was inside of a WAD located in a PK3 file.
Updated, text lumps tracking: already parsed DECORATE/GLDEFS lumps are now added to the text lumps list even when DECORATE/GLDEFS parsing fails, allowing you to fix errors without the need to use external tools.
Fixed: in some cases the editor could stuck in an infinite loop when searching for wad lumps.
Fixed: some map format conversion errors were never displayed, because errors list was cleared after performing map conversion.
Fixed: 3d floor indicators in 2D modes were not updated after leaving Visual mode.
Fixed: some UDMF-only interface buttons were never removed after converting map format from UDMF.
Added, Script Editor: MENUDEF and SBARINFO files/lumps are now shown in the Resources list.
Fixed, ACS handling: fixed a crash when trying to parse an #include file, when specified path was absolute.

Updated: sector triangulation logic now works ~20% faster.
Changed: a case when a pk3/pk7 archive contains several entries with identical filename is now treated as a warning, not as an error.

Probably fixed probable I/O race condition when loading images.
Fixed Visual mode stuttering due to floating point precision degradation when running the editor for several days without restarting (internal timer is now reset when saving the map or creating a new one).
Fixed, Nodes Viewer, cosmetic: Nodes Viewer window position was reset after pressing the "Rebuild Nodes" button.
Added Eternity Game configurations by printz.
Updated ZDoom_ACS.cfg (CheckClass).
Updated ZDoom ACC (CheckClass).
Changed, Sectors mode: "Flip Linedefs" and "Align Linedefs" actions will no longer flip single-sided linedefs with only front side.
Fixed, Script Editor: fixed a crash when trying to update script navigator combo box when switching to a never saved ACS script.
Changed, Browse Textures window: several textures with the same name were displayed in "All" texture set when overriding WAD textures by Folder/PK3 textures.
Fixed, Draw Geometry modes: fixed a crash when moving the mouse cursor over a vertex while holding Alt-Shift keys when there were no new points drawn in current mode.

Updated GZDoom_MODELDEF.cfg.
Fixed: voxel support logic was outdated, which in some cases resulted in voxels not being loaded and in some weird behaviour when trying to change pitch/roll of associated things.
Updated sprites lookup logic. Now it correctly handles sprites named like NNNNA0B0.
Fixed: in some cases DECORATE parser was unable to correctly detect sprite name & frame(s) block.
Updated ZDoom_ACS.cfg.
Updated ZDoom_DECORATE.cfg.
Changed, "Flip Linedefs" action: the action will no longer flip single-sided linedefs with only front side.
Fixed a crash when trying to determine sprite angles when images with non-sprite names, starting with expected characters, were present in the Sprites namespace.

Changed, TEXTURES parser: patch loading errors are now ignored for textures with "NullTexture" option.

Updated ZDoom_ACS.cfg.
Updated ZDoom_DECORATE.cfg.
Updated ZDoom ACC.
Changed, TEXTURES parser: patch loading errors are now treated as warnings for optional textures.
Changed, TEXTURES parser: patch loading is now skipped for textures with "NullTexture" option.

Fixed imprecise vertex coordinates generated by Draw Ellipse mode.
Fixed a resource loading exception when opened map file wad was located in the root of a Directory resource.
Internal: changed output of all InterpolationTools methods from int to float.

Fixed, DECORATE parser: actors, which used "replaces" keyword and didn't have DoomEdNum were ignored.
Updated documentation ("(G)ZDoom text lumps support" page).
