Major quality release: plugin visibility control, UI/UX polish, unified admin panel, database-backed settings, and security hardening. No breaking API changes.

#### Added
- **Plugin Visibility Control** (F.1): `ENABLED_PLUGINS` env var controls which plugins public users see. Default: `wordpress,woocommerce,supabase`. Admin sees all. New module: `core/plugin_visibility.py`
- **MCP Service Pages** (F.3): Dedicated `/dashboard/services/{type}` pages showing plugin capabilities, tool list, and setup requirements. Services list page with grid of plugin cards

- **Auth Page Language** (F.2): Auth page defaults to English regardless of Accept-Language header
- **Donation Link** (F.2): Moved from home page to sidebar for consistent visibility
- **Test Connection** (F.3): Fixed 504/HTML error handling; status badge auto-updates without page refresh; added `last_tested_at` timestamp (DB schema v4)
- **Admin Auth** (F.4): Fixed `_require_admin_session()` to recognize OAuth admin sessions; hide "Admin Login with API Key" button when `DISABLE_MASTER_KEY_LOGIN=true`
- **Starlette API** (F.2): Updated `TemplateResponse` to new API (request as first arg)

#### Security
- **exec() Removal** (F.8): Replaced `exec()` in `core/tool_generator.py` with closure-based tool generation
- **Shell Injection Fix** (F.8): Replaced `create_subprocess_shell` with `create_subprocess_exec` in WP-CLI handler
- **bcrypt Migration** (F.8): Admin API key hashing upgraded from unsalted SHA-256 to bcrypt

---

## [3.2.0] — 2026-02-25

### Fixed
- **Bug A**: OAuth consent redirect loop — after GitHub/Google login, page now returns to consent screen instead of `/dashboard`
- **Bug B**: `/u/{user_id}/{alias}/mcp` endpoint now accepts OAuth JWT tokens (issued after social login) in addition to `mhu_` API keys
- **Bug C**: OAuth users can now create, list, and delete their own OAuth clients via the new `/dashboard/connect/oauth-clients` page
- **D-1**: Dashboard sidebar border uses Tailwind class instead of inline style; version shown in footer
- **D-2**: Removed broken `setInterval` in dashboard that targeted non-existent `#stats-container`
- **D-3**: 404 page uses purple primary colors and respects system dark mode preference
- **D-4**: Fixed invisible buttons (`bg-gray-200` + `text-white` in light mode) across api-keys, health, projects pages
- **D-5**: Pinned Alpine.js to 3.14.8; removed duplicate CSRF meta tag from `head_assets.html`
- **D-6**: Fixed invisible language toggle button in settings (dark mode)

### Added
- `OAuthClient.owner_user_id` field for per-user OAuth client isolation
- `dashboard_connect_page` now includes Claude.ai connection guide with endpoint URL and link to OAuth Clients
- New route: `GET /dashboard/connect/oauth-clients` — user's OAuth clients list
- New API: `POST /api/dashboard/user-oauth-clients/create` — create OAuth client for logged-in user
- New API: `DELETE /api/dashboard/user-oauth-clients/{client_id}` — delete own OAuth client

## [Unreleased] - 2025-11-11

### 🔄 Architecture Refactoring (Option A)

**BREAKING CHANGE**: Removed per-site tools to prevent tool explosion.

#### Changed
- **Architecture**: Migrated from Hybrid to Unified-Only architecture
- **Tool Count**: Reduced from 390 to ~105 tools (constant regardless of site count)
- **Scalability**: Now supports unlimited sites without tool explosion
  - 1 site: 105 tools (was 200)
  - 10 sites: 105 tools (was 1055)
  - 100 sites: 105 tools (was 9600+)

#### Technical Details
- Per-site tools (e.g., `wordpress_site1_get_post`) are no longer registered
- Only unified tools (e.g., `wordpress_get_post(site="site1")`) are exposed
- Plugin infrastructure remains intact for internal use
- Site aliases continue to work seamlessly

#### Migration
- **Non-breaking for new users**: Use unified tools from the start
- **For existing integrations**: Update tool calls to use `site` parameter
  - Before: `wordpress_site1_get_post(post_id=123)`
  - After: `wordpress_get_post(site="site1", post_id=123)`

**Files Modified**:
- `server.py`: Removed per-site tool registration
- `MASTER_CONTEXT.md`: Updated architecture documentation
- `README.md`: Updated tool count and features

**Next Steps**: Option B (complete architectural cleanup) planned for separate branch.
