+Our changes include:
+ - Add a `code-server` schema.
+ - Make the extension sidebar work in the browser. Mostly involves removing
+   Node-specific code for the `extensions` channel client and adding a
+   `gallery` channel.
+ - Allow multiple extension directories (both user and built-in).
+ - Rewrite assets used in the CSS (like icons) or as images to use the base URL.
+ - Change the loader to use the base URL.
+ - Change the web socket to use the base URL.
+ - Set the favicon (using a relative path).
+ - Modify the file service to support writing from an asynchronous stream (for
+   uploading files).
+ - Add a file prefix to ignore for temporary files created during upload.
+ - Insert our upload service for use in editor windows and explorer.
+ - Modify the log level to get its initial setting from the server.
+ - Get telemetry working by adding a channel for it.
