 # Changelog
 
+## 2025-12-30 - 3.14.2 - fix(editor)
+bump monaco-editor to 0.55.1 and adapt TypeScript intellisense integration to the updated Monaco API
+
+- Bumped dependency monaco-editor from 0.52.2 to 0.55.1 in package.json.
+- Generated MONACO_VERSION module updated to 0.55.1 and moved target to ts_web/elements/00group-editor/dees-editor-monaco/version.ts.
+- Refactored TypeScript IntelliSense code to use a typed Monaco TS API (added IMonacoTypeScriptAPI, tsApi getter, and replaced direct monaco.languages.typescript.* calls).
+- Added test/workspace screenshot .playwright-mcp/workspace-test.png (binary asset).
+
 ## 2025-12-30 - 3.14.1 - fix(build)
 bump @webcontainer/api and enable skipLibCheck to avoid type-check conflicts
