 ### Added
 
+- Added `api.php` for authenticated remote management of content, media uploads, and comments.
+- Added a native SwiftUI macOS 12+ client under `macclient/` for editing posts/pages, uploading media, moderating comments, local autosave, and optional remote draft autosave.
 - Added a declared shortcode parser with PHP-array/JSON configuration, including `[youtube=<id>]` and `[video poster=<poster> file=<file>]`.
 - Added `lone-embed.php` as the generated HTML5 video player target for video shortcodes.
 
+### Changed
+
+- Blocked direct web access to the `macclient/` source folder through `.htaccess`.

 ```
 
+## Mac Client and API
+
+The native macOS 12+ client lives in `macclient/`.
+
+```bash
+cd macclient
+swift run TCMSMacClient
+```
+
+Point the client at any TCMS site URL. It will call `api.php` at that site for posts, pages, media, comments, local autosave restore, and optional remote draft autosave.
+
+For remote servers, set an API token in `config/site.json` or through the `TCMS_API_TOKEN` environment variable:
+
+```json
+{
+  "api": {
+    "enabled": true,
+    "token": "replace-with-a-long-random-token",
+    "allow_local_without_token": true
+  }
+}
+```
+
+Send the token as a Bearer token or `X-TCMS-Token`. Localhost requests may use the tokenless development fallback while `allow_local_without_token` is enabled.
+
 ## Comments

+```
+
+The client automatically calls `api.php` under that URL. If the server has an API token configured, paste it in Settings. Local development can use TCMS' localhost fallback when `api.token` is blank and `api.allow_local_without_token` is enabled.
+
+## Features
+
+- Create, edit, draft, publish, and delete posts and pages.
+- Upload media to `bl-content/uploads`.
+- List and moderate comments.
+- Local autosave to Application Support.
+- Optional remote autosave as draft.
+- Configurable autosave interval.
