## gostations ${VERSION}

New major release: full modern TUI (Bubble Tea) is now the default.

- Two-stage UI: station browser → dedicated playback view (Winamp-inspired)
- Live stream metadata display
- Playback controls: skip, volume (↑/↓ + vertical bar), mute, play/pause, stop (returns to list)
- mpv JSON IPC for responsive controls + metadata (no terminal takeover)
- Favorites (★) management in both TUI and CLI (fav list/add/del [index])
- Server-side search on ENTER while filtering
- Legacy wmenu UI still available via --legacy (for now)
- All previous CLI subcommands (find, play, fav) preserved

See the commit history and updated README for details.
