Version 9.5.0

Released Aug 2, 2026 - WinHTMLEditorControl 9.5.0 adds built-in wavy spell-check underlines, fixes spell-check refresh/completion issues, restores normal dialog labels, and adds an MCP server for AI assistants.

New features

  • Official MCP server for AI coding assistants, backed by an API-truth pipeline
  • Inline spell check now draws a real wavy squiggle by default, with nothing to deploy

Bug fixes

  • Toolbar Spell Check reports "Spell Check Complete." without checking anything when the first paragraph is clean
  • Inline spell check: changing the misspelled-word marker style at runtime does not restyle words already flagged
  • Shipped dialog labels rendered in all capitals (Style Builder, table, image, hyperlink, find, YouTube)
