Thanks to a new partner (www.radiopi.org) liquidsoap development took new directions and is very active. Radiopi should eventually move to liquidsoap, but they needed more. We gave them.
Liquidsoap can now have output nodes at any position in the scheduler tree, not only at the root. And those outputs can be desactivated from the telnet interface, which has been restarted from scratch.
We added features for live shows. First, a liquidsoap (server-side) can take a vorbis http stream as input. Then, a liquidsoap (client-side) can use alsa as input-output, together with an usual icecast output to stream the emission.
Some GUIs are coming for easier liquidsoap controlling, particularly needed for live shows.
