  • Improved the UI automation peer tree related to auto-hidden tool windows.
  • Updated Shift+Esc to close the active tool window.
  • Updated docking window close focus-moving logic to not possibly move focus into an auto-hidden tool window.

  • Fixed a bug where dynamically setting an image source on an auto-hidden ToolWindow wouldn't update the tab in a certain scenario.
  • Fixed a bug where an auto-hidden tool window might not render its child controls with the correct foreground.
  • Fixed a bug where docking windows in high DPI could initially float in the wrong location when dragged.
  • Fixed a bug where dock guides could render in the wrong location in a scenario when using .NET 4.8 and PerMonitorV2 DPI awareness.
  • Fixed a bug where SplitContainer didn't properly establish its child logical tree.
  • Fixed a bug where switcher activation keys used wouldn't work when a non-hosted auto-hide popup had focus.

  • Fixed a bug where dock guides and non-hosted auto-hide popups could appear in the wrong location in certain per-monitor high DPI scenarios.

  • Improved how numeric edit boxes parse whitespace within custom format string literals.
  • Updated the AutoCompleteBox.Text property to bind two-way by default.
  • Updated AutoCompleteBox to properly capture mouse events when the popup is open.

  • Updated MaskedTextBox to always move the caret immediately after the last matched character when the mouse tries to start selection in the prompt area.
  • Updated MaskedTextBox to move the caret past the literal characters in the mask when gaining focus.
  • Fixed a bug where Calculator didn't always detect its out-of-range state properly.
  • Fixed a bug where DoubleEditBox wasn't parsing percentage values correctly.
  • Fixed a bug where DoublePicker, SinglePicker, and Int64Picker might not increment values correctly when there was an enormous range allowed.


  • Updated PropertyGrid to prevent ObservableCollection property model refreshing when an item is replaced.
  • Improved the performance of moving a tree node to another location in the tree.
  • Fixed a bug where a BrushEditBox used in PropertyGrid wouldn't always raise the PropertyValueChanged event.
  • Fixed a bug where hidden columns wouldn't allow star width columns to size correctly.
  • Fixed a bug in how TreeListBox notified of multiple item removal.


  • Updated the mini-toolbar to not close when unfocused and the Ctrl or Shift modifier keys are pressed.


  • Added the ShellListView.SortDirection and SortShellPropertyKey properties, which determine how the list is sorted.
  • Added the ShellListView.CanResetSortOnRootShellFolderChange property, which can be set to false to prevent sort reset when the root folder changes.

  • Fixed a bug where caret movement didn't work properly around a collapsed region adornment at the end of a document.
  • Fixed a bug where the current line highlight bounds included any intra-line adornments.
  • Fixed a bug where a code snippet without any SnippetTypes specified should have been allowed anywhere.
