This new version has an overhauled "new map" screen, allows exporting map images without the raw map terrain layer, and has a bunch of fixes related to object overlapping, rebuild priority updating, the list-selection shortcuts and more. It also allows TD megamaps for singleplayer missions to be published to the workshop, since they can work with mods which enable that feature in-game.

All changes:

• The Cell Trigger tool's "jump to" function will now also jump to placed objects with the attached trigger, to easily review what uses it.
  
• The "jump to" function in Waypoints and Cell Triggers will now properly update the mouse cell info in the bottom bar.
  
• The [Briefing] and [Base] sections can now also accept custom ini keys (which can be useful for mods).
  
• Undo/redo operations are now blocked while mouse drag operations (moving or drag-placing objects) are in progress, to prevent corrupting the list of undo/redo operations.
  
• Fixed bug where having a specific tile from a random tiles group selected would still show the first tile of the group as placement preview.
  
• Added the ability to export map previews without the map templates layer. This will give an image with a transparent background.
  
• The tooltips showing which trigger criteria are needed for using a trigger in a certain situation will indicate which of the criteria are fulfilled by the currently selected trigger.
  
• The tooltips showing trigger criteria will now say "usable" events/actions rather than "required".
  
• The Zoom shortcuts now work on more keys than just the numpad ones.
  
• Fixed issues with how objects overlapped with each other. This doesn't 100% match the game, but the game's method for doing overlaps is often very strange and unrealistic.
  
• Refined the "outlines on overlapped objects" logic to only outline objects that are actually high enough up compared to the other object to be considered overlapped.
  
• Fixed a bug where Terrain objects would not show a placement preview over bibs.
  
• Fixed a bug in Walls mode where changing to a different type did not refresh the preview.
  
• Fixed a bug where switching back to the Terrain tool would show the previously-selected type in the preview, but would not select it in the list.
  
• Fixed a bug in Map mode where using the PageUp or Home key to select the Clear terrain would not scroll to the item in the list.
  
• Added setting to enable DPI awareness mode, for users with indicator scaling issues.
  
• Triggers on TD Terrain entries are now optional in the ini; terrain entries without the trigger part will no longer be skipped as malformed data.
  
• When loading a map and objects are detected as overlapping a multi-cell object like a building or tree, on top of giving the cell where the overlap occurred, the system will now also report the placement cell of that object.
  
• Overhauled the undo/redo system of building priorities, to remove inconsistencies.
  
• Modifying the rebuild priority of a placed building will now adjust the rebuild priorities of the other structures, as already happened when adding and removing them.
  
• Fixed bug where two buildings of different types placed on the same cell (e.g. a guard tower on the top-left corner of a repair bay) would not correctly be distinguished as different entries by the rebuild priority system, causing one of them to lose its rebuild status.
  
• The "Learning" and "Mercenary" options in the TD Teamtypes editor are now crossed out in the UI, and indicated on the tooltip as having no effect.
  
• Megamaps for TD can now be published on the Steam workshop, provided they are singleplayer scenarios. They will give a warning about the nonstandard format, though this is not re-shown for the same map on subsequent uploads.
  
• Added forgotten PageUp/PageDown/Home/End shortcuts support to the Walls tool.
  
• Buildings now all have a set height to control overlaps.
  
• Civilian building V37, The Studio, is now seen as a flat building, lower than even the repair bay, so its top left corner can't overlap other objects. (Sadly, the game does not do this.)
  
• Fixed column resizing in the triggers list so it always maximizes the clickable area to select a trigger, and never gives scrollbars unless needed.
  
• The mplayer.ini file tweaks are now only applied if RA's Aftermath expansion units are enabled, as it should.
  
• The editor will now be allowed to load in classic mode without the RA expansion files present. Any missing graphics will be substituted by dummy graphics.
  
• Overhauled the "New Map" dialog using list boxes, to have more consistent tab order control, and to allow more easily modding in additional games / theaters.
  
• Added "Single-Player Scenario" checkbox on the "New Map" dialog.
  
• Added remap logic to fix Einstein's colors, using the remap system used by the other RA civilians.
  
• The power evaluation tool now takes buildings' damaged status into account when calculating the produced power.
  
• Multiple overlapping multiplayer flags will now be drawn as multiple flags on one cell, scaling down later overlapping ones.
  
• Multiple overlapping non-flag waypoints will no longer show up brighter on the map.
  
• Added option to let the editor remember tool selection information between different opened maps of the same type. This option is disabled by default.
  
• Left-clicking on smudge no longer copies its properties into the tool, since left-click is needed to change smudge properties.
  
• Removed "NoMetaFilesForSinglePlay" option, since the meta files are always 100% useless in single play, and instead added "ClassicProducesNoMetaFiles" to suppress the creation of such files for all maps in classic mode.
  
• In old Red Alert maps which use Italy instead of Ukraine, The house settings for [Italy] will now be applied to Ukraine.
