Features 1

  1. NWIN-10: Built-in dark mode theme

Bug fixes 17

  1. ScrollBarSetting does not suppress excluded native document scrollbars
  2. Word paste joins words across inline font changes
  3. Outlook paste loses standard table borders and cell spacing
  4. In preview mode a clicked link navigates inside the editor instead of opening the default browser, and no documented hook intercepts it
  5. Inline spelling replacement could lose the redo branch after Undo
  6. YouTube dialog initially clipped the related-video option below the footer
  7. Hyperlink dialog clipped the Overwrite option at its initial width
  8. Style Builder captions disappear under Windows high contrast
  9. Empty dialog fields lack visible outlines in dark and high-contrast themes
  10. HtmlElementClicked and HtmlElementMouseDown were never raised, and Ctrl+Click executed any link address including file paths
  11. Style Builder border-width captions are clipped at the default dialog size
  12. A search dialog opened by the host code (for example pre-filled with PreloadedSearchText) did not find or replace anything
  13. Body-only Source round-trip changes the retained document's rendering mode
  14. Context-menu items bound to ApplicationCommands (Cut, Copy, Paste) in a replacement EditorContextMenuStrip were disabled and did nothing
  15. An opened document lost its relative stylesheet even with BaseUrl set, and Content.OpenFile threw NullReferenceException
  16. After an action was rebound or disabled, its built-in browser shortcut still worked (for example Ctrl+B still bolded after Bold moved to Ctrl+Shift+B)
  17. Cached and nested dialogs can use the wrong host owner or separate taskbar entry
