This is the second bugfix release of the liquidsoap 2.0.x branch. It contains important fixes and a couple of enhancements. Update is recommended with a little bit of testing before.

Noticeable new features are:

• We now show highlighted code excerpts on errors, which should help finding out which part of a script are not working
• We export the last_metadata of a source, which can be used to make transitions between sources easier.

Noticeable bug fixes are:

• Fixed a segfault in ocaml-lame. Make sure to install version 0.3.5
• Fixed a memory leak when using muxing operators.
• Fixed last metadata not showing up in some switches or fallback
• Fixed input.rtmp deadlocking on shutdown
• Fixed %ffmpeg copy encoder crashing when switching sources.

We believe that this release is bringing liquidsoap 2.0.x to a great level of stability and have worked on it with a couple of partners implementing it for their streaming systems. We suggest to upgrade whenever possible. However, because of the changes in metadata behavior with switches, it might be good to do some minimal testings beforehand. If anything, though, the change in behavior should bring liquidsoap back where most users would expect it to be.

As usual, we want to warmly thank all users, bug reporters and contributors for their invaluable help and patience working with us on this release!
