+## [1.2.0] - 2025-08-18
+
+### Added
+- New `artist` command to download an artist’s top tracks.
+- `--limit` flag for the `artist` command to restrict the number of tracks.
+- `--strict` flag for downloads: fail if the requested quality is unavailable.
+
+### Changed
+- Default download quality is now **MP3 320kbps**.
+
+### Removed
+- The `--quality=best` option. Fallback to lower quality is now the **default behavior**; use the new `--strict` flag if you want to prevent fallback.
+
+### Fixed
+- Handle error when `SNG_CONTRIBUTORS` metadata is empty.
+
+## [1.1.1] - 2025-06-16
+
+### Fixed
+- Restored ability to download tracks **without a Deezer Premium account** (limited to **MP3 128kbps** for free accounts).

 ### Changed
 - The `.godeez` file in the user’s home directory has been replaced by a `.godeez/` directory.  
   It now stores both `config.toml` and the internal `tracks.db`.
