 ### Added
 
+- Follow the operating system's native theme on macOS, Windows and Linux (KDE, GNOME) via `native-theme`, applying the OS colors, fonts, radii and accessibility preferences; the bundled themes remain as the fallback when the OS theme cannot be read
 - Add an identity import dialog, importing an existing identity by pasting its `nsec` secret key (encrypted with a new passphrase), NIP-49 `ncryptsec` (unlocked with its passphrase), or `bunker://` NIP-46 URI
 - Add a dropdown menu on the signed-in user button in the sidebar
 - Add sign-out feature, confirmed by an alert dialog before deleting the stored session credential

 ### Removed
 
+- Remove the light/dark theme pickers and the font size, corner radius, focus ring and shadow settings from the settings dialog; colors and geometry now come from the native theme
 - Remove dead code: the unused `login`/`logout` family, the unwired `SyncProgress` pipeline, `merge_pull_request`, inbox mark-read/archive APIs and the wasm32-only code paths
 
 ### Deprecated
