Fixed: in some cases generalized sector effect detection logic failed to detect a valid generalized effect.
Fixed, Action selector control: action label was not updated when changing action number from one generalized effect to another.
Fixed a crash when trying to store a custom field with "Byte Angle" type.
Fixed: in some cases custom field types stored in the map's .dbs file were not applied when loading a map.
Added, Sound Environments mode: current sound environment is now highlighted (can be toggled using "Toggle Highlight" action).
Added: Tag selectors now have up/down buttons.
Fixed, Sound Environments mode: sound environments were not updated after performing Undo/Redo actions.
Fixed, Sound Propagation mode: sound zones were not updated after performing Undo/Redo actions.
Internal: moved "Toggle Highlight" action to the core, also changed it's category to "View".
Internal: "Toggle Highlight" action state is now saved in the Program configuration.
Updated ZDoom_DECORATE.cfg (GetZAt).
Updated ZDoom_linedefs.cfg (Sector_SetPortal args).
Fixed, Visual mode: both "With same texture" and "With same height" Select modifiers are now checked when both of them are used at once (previously a sidedef part/floor/ceiling was selected when any of those matched).
Fixed, Sound Environment mode: in some cases the view was not updated after updating sound environments.
Added, Sound Environment mode: Sound environment things of currently highlighted sound environment are now highlighted.
Added/restored, Visual mode: restored "Move Texture Left/Right/Up/Down by 8" actions, added "Move Texture Left/Right/Up/Down by Grid Size" actions (default keys are Ctrl+arrow keys).
Fixed, Game configurations: Hexen's Bell actor was missing "hangs" flag.
Fixed, Sectors mode: tags and effect labels were displayed instead of selection number labels after disabling, then enabling selection numbers when there were sectors with tags or effects selected.
Fixed severe lock-up after finishing dragging many vertices/linedefs/sectors in Classic modes.
Updated documentation ("Synchronizing camera position").
Fixed, general interface: in some cases opening "Test Map" drop-down resulted in an exception when trying to access a disposed/non-existing test engine icon.
Currently this will work as intended only if the selection ends up either completely inside a single sector or completely outside of any sector. Also this logic won't be applied if the selection contains the lines with only start or end vertex selected.
Internal: some TextLabel refactoring.
Fixed: there can be several entries of the most ZDoom text lumps in WADs. Previously only the first one was processed.
Internal: rewritten DirectoryFilesList to use one collection instead of two.
Fixed, Visual mode: in some cases not all sidedef geometry was updated when updating sectors with Plane Align (181) action. Also fixed some more unnecessary geometry updates.
Fixed, Linedefs mode, Things mode: in some cases deleting linedefs/things caused a crash when trying to update text labels.
Fixed, Draw Lines mode: in some cases the drawing was prematurely finished when "Auto-finish drawing" option was enabled.
Changed, Draw Lines mode: line angles are now shown only when "Show guidelines" mode is enabled.
Fixed, Draw Lines mode: in some cases "Snap to cardinal directions" mode was snapping only to diagonals.
Fixed, Draw Lines mode: snap to geometry behaved incorrectly when "Snap to cardinal directions" mode was enabled.
Changed, Things mode: dynamic light shape is now drawn using highlight color when a dynamic light thing is highlighted.
Added more sanity checks to MODELDEFS parser.
Fixed: CVARINFO parser was unable to parse negative int/float values.
Fixed: in some cases TextLabel text size was checked before it was calculated.
Internal, Visual mode: reduced the number of unnecessary geometry updates when changing map geometry.
Updated ZDoom_DECORATE.cfg (atan2 and VectorAngle).
Fixed, Script Editor: fixed infinite loop when trying to search for empty string.
Changed, Linedefs mode: selection labels are now positioned in a less line angle obscuring way.
Changed, Draw Lines mode: text label background alpha didn't match the alpha of the labels used in other classic modes.
Updated ZDoom_ACS.cfg (SetMusicVolume).
Updated ZDoom ACC (SetMusicVolume).
Updated, Game configurations: some linedef action arguments now use type 26.
Updated documentation ("Game Configuration - Action Argument Settings").
Updated ZDoom ACC (APROP_MaxStepHeight and APROP_MaxDropOffHeight).
