 # Changelog
 
+## 2026-01-02 - 3.28.0 - feat(dees-appui)
+Rename DeesAppuiBase to DeesAppui and migrate related API, exports, demos and docs
+
+- Renamed public component/tag and TypeScript types: DeesAppuiBase -> DeesAppui and TDeesAppuiBase -> TDeesAppui; updated IViewActivationContext.appui type accordingly
+- Moved/rewired view registry implementation from dees-appui-base to dees-appui and updated module exports
+- Updated README and demo files to reference DeesAppui and new readme paths (removed dees-appui-base docs/demo)
+- Replaced dependency/imports of '@webcontainer/api' with '@tempfix/webcontainer__api' (package.json and source imports)
+- Changed tsconfig.json: skipLibCheck set from true to false
+
+## 2026-01-01 - 3.27.1 - fix(dees-actionbar)
+always render actionbar wrapper and delay adding visible class to ensure grid/opacity animations run reliably
+
+- Always render the actionbar wrapper (.actionbar-item and .actionbar-content) instead of returning early so grid-template-rows and opacity transitions can animate.
+- Use optional chaining for current bar access (bar?.type, bar?.timeout) to avoid runtime errors when no bar is present.
+- Adjust styles and structure: set :host display:block; move background/border to .actionbar-item; add .actionbar-content with min-height/opacity and transitions.
+- Make processQueue asynchronous and await updateComplete, then add the 'visible' class inside requestAnimationFrame so the CSS transition is triggered after render.
+
+## 2026-01-01 - 3.27.0 - feat(services)
+introduce DeesServiceLibLoader to lazy-load heavy client libraries from CDN and update components to use it
+
+- Add DeesServiceLibLoader singleton (ts_web/services/DeesServiceLibLoader.ts) to lazily load and cache libraries via jsDelivr ESM: xterm, xterm-addon-fit, highlight.js, ApexCharts, and Tiptap.
+- Inject xterm CSS dynamically to avoid shipping xterm styles in the initial bundle.
+- Expose helper methods preloadAll() and isLoaded(), and typed bundle interfaces (IXtermBundle, IXtermFitAddonBundle, ITiptapBundle).
+- Update components to use runtime-loaded modules: dees-chart-area, dees-dataview-codebox, dees-input-richtext, wysiwyg code block, dees-workspace-terminal, terminal-tab-manager, dees-workspace-terminal-preview.
+- TerminalTabManager now requires setXtermModules(...) before creating tabs and will throw if not initialized; workspace terminal now initializes and passes the loaded modules.
+- Replace direct runtime imports of heavy libs with typed imports and runtime-loaded bundles to reduce initial bundle size and improve load performance.
+
+## 2026-01-01 - 3.26.1 - fix(dees-actionbar)
+animate actionbar hide using grid-template-rows and wait for animation before clearing state
+
+- Switch host layout from block/max-height to grid using grid-template-rows for open/close transitions
+- Add min-height: 0 to .actionbar-item to prevent flex children overflow and collapsing
+- Introduce async hideCurrentBar() that removes 'visible', sets isVisible=false, waits 220ms then clears currentBar and currentResolve
+- processQueue() now calls hideCurrentBar() asynchronously instead of clearing state immediately
+
+## 2026-01-01 - 3.26.0 - feat(workspace)
+add external file change detection, conflict resolution UI, and diff editor
+
+- Watch open files for external changes with debounced file watchers (startWatchingFile/stopWatchingFile/stopAllFileWatchers).
+- Prompt the user when disk changes conflict with unsaved local edits via dees-actionbar (actions: Load from Disk, Save Local, Compare).
+- Introduce dees-workspace-diff-editor component and export it; support comparing and resolving diffs (diff-resolved / diff-closed events).
+- Add setContentExternal in dees-workspace-monaco to update editor content from external sources while optionally preserving cursor, selections and scroll position.
+- Start/stop file watchers when files are opened/closed and integrate diff view and actionbar into the workspace UI for seamless conflict handling.
+
+## 2026-01-01 - 3.25.0 - feat(dees-actionbar)
+add action bar component and improve workspace package update handling
+
+- Introduce dees-actionbar component (dees-actionbar.ts) with interfaces, queueing, timed auto-trigger and demo usage
+- Add actionbar.interfaces.ts and index export; export dees-actionbar from elements index
+- Enhance workspace bottombar: add pendingPackageUpdate flag, process-complete handler, and connected/disconnected listeners to auto-refresh package status after updates
+- Make pnpm outdated checking robust by streaming output via a reader and adding a 10s timeout to avoid hanging; handle timeout and stream cancellation
+- Update package update commands to include '--latest' for updatePackage and updateAllPackages, and show 'Checking...' label during checks
+- Add '@types/node' (^22.0.0) to devDependencies in the workspace package config
+
+## 2026-01-01 - 3.24.0 - feat(workspace)
+add workspace bottom bar, terminal tab manager, and run-process integration
+
+- Add dees-workspace-bottombar component and export; bottom bar emits run-process events to launch processes.
+- Introduce terminal interfaces (IRunProcessEventDetail, ITerminalTab, ICreateTerminalTabOptions, etc.) and a TerminalTabManager to manage multiple terminal tabs and lifecycle.
+- Integrate bottombar into dees-workspace: layout refactor (workspace-outer), move/adjust resize handles and panels, and handle @run-process to create terminal tabs and focus terminal panel.
+- Enhance dees-workspace-terminal: tabbed terminal UI, new public APIs (createProcessTab, writeToTab, sendInputToTab), theme updates, and improved disposal/cleanup behavior.
+- Update module exports to include bottombar and additional terminal sub-exports (interfaces, terminal-tab-manager).
+
+## 2025-12-31 - 3.23.0 - feat(workspace)
+add resizable file tree and terminal panes with draggable handles and public layout APIs
+
+- Introduce reactive state for currentFileTreeWidth, currentTerminalHeight, isDraggingFileTree and isDraggingTerminal
+- Add mouse event handlers (mousedown/move/up) to drag-resize the file tree and terminal with min/max clamping
+- Dispatch window resize event after resizing to notify Monaco/editor of layout changes
+- Clean up resize event listeners in disconnectedCallback
+- Initialize current sizes from component properties in firstUpdated
+- Expose public layout methods: setFileTreeWidth, setTerminalHeight, resetLayout
+
+## 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
