+## [0.2.2] - 2026-07-25
+
+### Added
+- **French (fr) locale**: Complete translations for all 60+ UI keys.
+- **Outline scroll tracking**: Active heading auto-highlights in outline panel as you scroll.
+- **Table auto-format**: `exec('formatTable')` aligns column widths in Markdown tables.
+- **Code block title**: ` ```js title=hello.js ` renders a styled title bar above code blocks.
+- **Escaped pipe in tables**: `\|` in table cells no longer splits columns.
+- **Custom block token fallback render**: Unknown token types now render as `<div class="me-block-{type}">` instead of empty string.
+- **Gutter incremental update**: Line number gutter uses DOM diff instead of full innerHTML replacement.
+- **694 tests** (up from 684).
+
+### Changed
+- **All 6 plugins now use closure-based state** — searchReplace, imagePaste, shortcutHelp, fileSystem, autoSave refactored for thread safety.
+- **shortcutHelp plugin is now i18n-aware** — shortcut descriptions follow the active locale.
+- **Context menu labels (Cut/Copy/Paste/Select All) are now i18n-translated** across all 5 locales.
+- **Warm theme now includes `progressBg` and `closeHoverBg`** for completeness.
+- **Fenced code block regex improved** to capture optional info string attributes.
+
+### Fixed
+- Plugin `this` context pollution eliminated for all 6 preset plugins.
+- Context menu labels no longer hardcoded to English.
+- Warm theme missing CSS variable fields restored.
