New Version


  • Reimplemented and improved the line modification mark tracking logic, also added reverted change display capabilities.
  • Added the ITextChangeOptions.CanMergeIntoPreviousChange property, which can be set to true to indicate that a programmatically-created text change should be merged into the previous text change on the undo stack.
  • Added the ITextChange.IsMerged property that returns if a text change is the result of two or more merged text changes.
  • Added the SyntaxEditor.CanBackspaceOverSpacesToTabStop property that can be set to false to only allow backspacing over a single character when ITextDocument.AutoConvertTabsToSpaces is true.
  • Added UI automation peers for IntelliPrompt quick info, parameter info, and completion lists.
  • Added an overload for the IUndoHistory.Clear method that specifies whether to also reset all change tracking, and added the IUndoHistory.Cleared event.
  • Updated the PasteDragDrop event to be raised for drag over events so that the drag effects can be manually altered. Normally events for PasteDragDropAction.DragOver can be ignored.
  • Updated the ITextChange.CustomData property to be settable.
  • Updated line number display to adjust appropriately when the first characters in a line are completely collapsed without an intra-text adornment in their place.
  • Updated text drags to not scroll past the document end when the CanScrollPastDocumentEnd option is enabled.

Web Languages Add-on

  • Added a text formatter for the JSON language that beautifies the data.


  • Fixed a bug where decoration adornments could render incorrectly when intersecting collapsed ranges.
  • Fixed a bug where deleting lines near the end of a document could cause the remaining line numbers to not refresh properly.
  • Fixed a bug where making the line number margin visible could initially render it with incorrect width.
  • Fixed a bug where line indicators didn't toggle properly on an empty line.
  • Fixed a bug where setting an invalid font family name could cause an exception if the line number margin was visible.

.NET Languages Add-on

  • Fixed a bug where the resolver was working on the name of named attribute arguments.
  • Fixed a bug where documentation comments within a region directive block could prevent the region from being code outlined properly.
