+# Gloss 1.0.5
+
+Gloss 1.0.5 fixes browser extension setup for existing installations.
+
+## Browser extension
+
+- Migrates recognizable legacy extension directories that predate the Gloss management marker.
+- Preserves overwrite protection for unrelated or modified extension directories.
+- Restores the **Show Extension** action without requiring users to delete or reinstall the extension manually.
+
+Gloss 1.0.5 requires macOS 14 or newer.
