Subsonic is a Web-based media streamer. Although primarily designed for MP3, it works for any media format that can stream over HTTP (for instance WMA and OGG). With Subsonic you have access to your entire music collection wherever you are. It is designed to handle very large music collections (many thousand albums). It uses a combination of directory structure and tag parsing to organize the music.
Scanning of music folders has been optimized, with dramatic improvement for network disks in particular. This release also contains some minor bugfixes.
