Sectors mode: removed "Move Things in Selected Sectors" toolbar button.
Sectors mode: added "Synchronized Things Editing" menu item, action and toolbar button. When enabled, things dragging will be synchronized to sector dragging. Regular, Paint and Rectangular selection will also select things (holding Alt while selecting inverts this behavior). Deleting sectors will also delete selected things.
Linedefs mode: added "Synchronized Things Editing" menu item, action and toolbar button. When enabled, selected things will be dragged when dragging linedefs. Rectangular selection will also select things (holding Alt while selecting inverts this behavior).
Changed: selection info now always displays info about all types of map elements.
Fixed: .dbs containing only current map settings was created when trying to save unchanged map.
Fixed, Visual mode, "Copy Texture" action: when "Use long texture names" option is disabled, texture name as stored in Sidedef should be used, not the 8-char texture name.
Updated documentation.
Changed, Drag Linedefs/Vertices/Sectors/Things modes: line length labels are now displayed the same way as in Draw modes.
Changed, Drag Linedefs/Vertices/Sectors/Things modes: "lock movement to cardinal directions" mode (Alt-Shift-Drag) now locks movement in 4 directions instead of 8 and doesn't snap map elements to nearest grid intersections when they are not aligned to it.
Added, Visual mode, GZDoom, DECORATE: FORCEXYBILLBOARD flag is now supported.
Added, Visual mode, GLOOME, DECORATE: FLOORSPRITE, CEILSPRITE, WALLSPRITE, ROLLSPRITE and STICKTOPLANE flags are now supported (implementation is somewhat broken ATM and probably doesn't work the same way as in GLOOME, because Windows build with most these features is nowhere to be found...).
Fixed, Visual mode: in some cases Thing brightness was calculated incorrectly.
Updated ZDoom_DECORATE.cfg.
General interface: selection info is now always displayed.
Visual mode: you can now hold Alt-Shift or Ctrl-Alt while selecting sidedefs to stop selecting connected sidedefs when already (un)selected sidedef is encountered.

Changed: Update checker now displays messages using MessageBoxes when called manually.
Map Analysis: changed result descriptions for Unknown Texture and Missing Texture checks.
Doom map format: renamed "Secret" linedef flag to "Shown as 1-sided on automap".
Updated ZDoom_DECORATE.cfg (A_RadiusGive stuff).
Changed: current 2D position and zoom is now stored in the .dbs file when saving the map and restored when opening it (should this be turned into toggleable option?).
Draw Lines mode, Draw Curve mode: you can now hold Alt - Shift to snap to 8 cardinal directions.
Draw Rectangle mode, Draw Grid mode: you can now hold Alt - Shift to draw square shapes.
Draw Ellipse mode: you can now hold Alt - Shift to draw circle shapes.
You can now hold Alt - Shift to snap to 8 cardinal directions while dragging map objects.
Fixed, Draw Lines mode: line angle is now displayed in 0..359 range (was -45..314).
Fixed, Linedef info panel: line angle is now displayed in 0..359 range (was -45..314).
Find and Replace Mode: renamed "Linedef Actions" search mode to "Linedef Action and Arguments".
Find and Replace Mode: renamed "Thing Action" search mode to "Thing Action and Arguments".
Cosmetic layout changes in Find and Replace window.
Updated documentation.
Changes in "Linedef Action and Arguments" and "Thing Action and Arguments" search modes:
Changed arguments search syntax from "action;arg0,arg1,arg2,arg3,arg4" to "action arg0 arg1 arg2 arg3 arg4"
You can now find ACS script actions with named scripts using "action arg0str ..." syntax.
You can now replace arguments using the same syntax as in the "Find what" field.
Visual mode: removed "Fit Texture's Width" and "Fit Texture's Height" actions.
Visual mode: "Auto-align texture offsets" actions were incorrectly aligning double-sided middle walls in some cases.
Visual mode: "Auto-align texture offsets" actions now align non-wrapped double-sided middle walls to vertical offset closest to their initial vertical offset.

Visual mode: using "Raise/Lower Floor/Ceiling to adjacent sector" actions on a thing with "+SPAWNCEILING" flag now works the same way as when using them on a regular thing.
Rendering: even more fixes to MODELDEF and UDMF properties-related model rendering logic.
Internal, ResourceListEditor: rewritten resource validation check in a more OOP-ish way.
Configurations: fixed an infinite loop crash when a file was trying to include() itself.
