 # Changelog
 
+## 2025-12-31 - 3.22.0 - feat(workspace)
+add resizable markdown editor/preview split with draggable handle and markdown outlet styling/demo
+
+- Introduce a flexible split layout for the workspace markdown editor with a draggable resize handle (splitRatio, minPanelSize, dragging state, mouse handlers and cleanup).
+- Enhance dees-workspace-markdown: switch from grid to flex, add resize handle UI, prevent pointer selection while dragging, notify Monaco on resize.
+- Add comprehensive styling and demo content for dees-workspace-markdownoutlet (dark/light themed markdown styles, syntax highlighting classes, and demo scenarios).
+- Fix typescript-intellisense monaco model update: only set model value when content actually changed to avoid cursor resets.
+- Add markdown outlet demo helper and numerous screenshot/image assets (.playwright-mcp) for demos/documentation.
+
+## 2025-12-31 - 3.21.0 - feat(terminal)
+add dynamic bright/dark theming for terminal components and terminal preview
+
+- Add bright/dark theme PNG assets under .playwright-mcp for previews.
+- Replace hardcoded terminal background/colors with cssManager.bdTheme in workspace terminal and preview styles.
+- Introduce getTerminalTheme helper to compute xterm theme for bright/dark modes.
+- Subscribe to themeManager.themeObservable and apply updates to xterm (terminal.options.theme) so terminals update live on theme change.
+- Remove hardcoded background property/CSS var and unused background accessor from workspace terminal.
+- Ensure proper cleanup: unsubscribe theme subscriptions and dispose terminals in disconnectedCallback.
+
+## 2025-12-31 - 3.20.1 - fix(dees-workspace)
+fix demo wrapper and workspace layout; always render terminal preview
+
+- Import @design.estate/dees-wcctools/demotools and wrap demo content in <dees-demowrapper>
+- Create an absolute-positioned container so the dees-workspace fills 100% height/width
+- Always render dees-workspace-terminal-preview (use empty command when none) to avoid conditional rendering issues
+- Set a fixed height (200px) for the terminal preview in the initializing state
+- Add Playwright demo asset .playwright-mcp/dees-workspace-demo-4k.png
+
+## 2025-12-31 - 3.20.0 - feat(workspace)
+rename editor components to workspace group and move terminal & TypeScript intellisense into workspace
+
+- Renamed components and modules from 00group-editor/dees-editor-* to 00group-workspace/dees-workspace-* (e.g. dees-editor-monaco -> dees-workspace-monaco).
+- Moved terminal implementation from dees-terminal to dees-workspace-terminal and updated related imports/usages.
+- Moved TypeScript intellisense manager into 00group-workspace and updated paths.
+- Updated ts_web elements index to export 00group-workspace instead of 00group-editor and adjusted internal imports accordingly.
+- Updated scripts/update-monaco-version.cjs to write MONACO_VERSION into the new workspace path and updated log tags.
+
+## 2025-12-31 - 3.19.1 - fix(intellisense)
+Debounce TypeScript/JavaScript IntelliSense processing and cache missing packages to reduce work and noisy logs
+
+- Add 500ms debounce in editor workspace to avoid parsing on every keystroke
+- Introduce notFoundPackages cache to skip repeated filesystem checks for packages without types
+- Clear not-found cache when scanning node_modules so newly installed packages are re-detected
+- Remove noisy console logs and make file/directory read errors non-fatal (ignored)
+- Simplify processContentChange signature (removed optional filePath) and remove manual diagnostic refresh logic
+
+## 2025-12-31 - 3.19.0 - feat(dees-editor-workspace)
+improve TypeScript IntelliSense, auto-run workspace init commands, and watch node_modules for new packages
+
+- Execute an onInit command from /npmextra.json on workspace initialization (e.g., run pnpm install).
+- Add npmextra.json and an import test file (importtest.ts) plus a sample dependency in the scaffold to test package imports.
+- Add node_modules watcher with debounce to auto-scan and load package types after installs.
+- Enhance TypeScript IntelliSense: recursively load all .d.ts files from packages and @types packages, add package.json as extra lib, and log progress/errors for debugging.
+- Change processContentChange signature to accept optional filePath and trigger a diagnostic refresh when new types are loaded.
+- Expose scanAndLoadNewPackageTypes to scan top-level and scoped packages and load their types.
+- Add start/stop logic for the node_modules watcher in workspace lifecycle to avoid leaks and handle cleanup.
+
+## 2025-12-31 - 3.18.0 - feat(filetree)
+add filesystem watch support to WebContainer environment and auto-refresh file tree; improve icon handling and context menu behavior
+
+- Add IFileWatcher interface and watch(...) signature to IExecutionEnvironment.
+- Implement watch(...) in WebContainerEnvironment using WebContainer's fs.watch and return a stop() handle.
+- dees-editor-filetree: start/stop file watcher, debounce auto-refresh on FS changes, cleanup on disconnect, and track last execution environment.
+- Add clipboard state (copy/cut) and related UI/menu enhancements for file operations (new file/folder, rename, delete, copy/paste).
+- dees-icon: default to Lucide icons when no prefix is provided.
+- dees-contextmenu: remove 'lucide:' prefix usage in templates and avoid awaiting windowLayer.destroy() to provide instant visual feedback.
+- Menu item shape adjusted (use { divider: true } for dividers) and various menu icon name updates.
+
 ## 2025-12-31 - 3.17.0 - feat(editor)
 add file explorer toolbar, empty-space context menu, editor auto-save, save-all, and keyboard save shortcuts
