Release v26.2.9

26.2.9

• Added experimental Markdown LSP support with settings for server command/arguments
  (for #3467)
  • The integration is experimental and currently provides completions via the autocomplete action
  • LSP info logs are no longer shown as warnings; only error-like stderr output is surfaced
  • Diagnostics published by the LSP server are now displayed as wave underlines in the editor;
    severity is reflected by color: red for errors, orange for warnings, blue for information,
    and green for hints
  • Hovering over a diagnostic underline shows a tooltip with the diagnostic message
  • Diagnostics are cleared automatically when switching to a different note
• Fixed a vertical stripe flickering artifact in the QLiteHtml preview when dragging to select text
  (for #3466)
  • Degenerate zero- or negative-width selection highlight rects are now suppressed; these were
    generated when the cursor was at or near the start of a text element, causing a 1-pixel-wide
    highlight to be painted over the full height of the preview during mouse-drag selection
  • Mouse-move repaints now use a single full-viewport update instead of multiple partial dirty-rect
    updates, preventing intermediate frame artifacts during rapid selection drags
• Improved text selection contrast in the QLiteHtml preview, especially in dark mode
  (for #3466)
  • Selected text now uses the palette highlight text color (QPalette::HighlightedText) instead of
    the original CSS text color, ensuring readable contrast over the selection highlight background
