# Changelog

## developmentVersion dev-0.7.1 / build 20260624.001

- Added package-prefixed command aliases such as `uctl.file.save`, `uctl.file.saveAs`, `uctl.edit.undo`, `uctl.view.testRun` and `uctl.host.integrationInfo` while keeping the legacy dev-0.7.0 command IDs available.
- Added command contribution metadata so Hosts can compose UnifiedControl commands into Host-owned MenuBar / Toolbar / ContextMenu surfaces without relying on UnifiedControl DOM.
- Added Control APIs: `getCommand()`, `getCommands()`, `getCommandAliases()`, `getCommandContributions()` and `registerCommandAlias()`.
- Added Workbench visibility options for title, MenuBar and Toolbar to support Window-contained and page-contained Host profiles.
- Strengthened Runtime rendering for input value lifecycle, radio groups, checkbox values, disabled / readonly / hidden / locked states, safe image URLs and HTML Block sanitization.
- Strengthened ContentRuntimeControl so `loadContent()` re-renders an already mounted runtime control and publishes `runtimeValueChanged` state.
- Hardened `.uctlx` package validation for safer path traversal checks, entry-count limits and manifest content-path consistency.
- Added regression coverage for command aliases / contributions, runtime radio values and HTML sanitization.

## dev-0.3.4
- Toolbar buttons are now icon-only with labels provided as title / aria-label hints.
- Direct Add TextBox / Add Panel toolbar buttons were removed; component creation is palette-first.
- New Content activates the Palette tab so users can immediately add components.

## developmentVersion dev-0.3.3 / build 20260618.003

- Renamed the official Control base class from `BaseControl` to `Control`.

## developmentVersion dev-0.2.2 / build 20260617.004

## developmentVersion dev-0.2.1 / build 20260617.003

- Improved Japanese / English / Chinese i18n coverage for the basic demo, Palette, Inspector property labels, component labels, and status messages.
- Replaced placeholder square toolbar/menu/palette icons with CSS-only semantic icons so the toolbar no longer looks like unchecked checkbox controls.
- Added localized default component labels when new components are inserted on the designer canvas.
- Hardened demo frame layout to avoid viewport-edge clipping and unintended outer scrolling in Host-like embedding.

## developmentVersion dev-0.2.0 / build 20260617.002

- Added `scripts/workbench/view_registry.js`.
