+1.0.0 beta1 (06-09-2010)
+========================
+This beta version introduces two major new features: heterogeneous stream
+types and clocks.
+New:
+ - Different sources can carry different types of content.
+ - Encoding formats have been introduced to help infer stream content types.
+ This brings static checking for bounds in encoding parameters.
+ - Introduce conversions between stream contents (mono, stereo, drop
+ audio, video, etc) and muxing.
+ - Allow explicit type annotations in scripts.
+ - Introduce clocks, cleanly allowing for the coexistence of different
+ time flows, and avoiding inconsistencies that can result from it.
+ Soundcard I/O and cross-based operators notably make use of it.
+ - Remove root.sync, replaced by attaching a source s to clock(sync=false,s).
+ - Enable dynamic source creation and source.shutdown().
+ - Extend and adapt MIDI and video operators.
+ - Introduce purely metadata streams (audio=video=midi=0 channels) and
+ metadata stream decoder.
+ - Support WAV streams in input.http/harbor().
+ - Introduce static image decoder using SDL image.
+ - Remove bound of request identifies (RID).
+ - Experimental: source.dynamic() for advanced dangerous hacking.
+ - Make path relative to script in %include "PATH", and introduce
+ %include <...> where path is relative to liquidsoap library directory.
+ - Add channels_matrix parameter to output.ao().
+ - Add on_(dis)connect hooks in input.harbor().
+Cleanup and fixes:
+ - Lots of cleanup and fixes as with all major code rewriting.
+ - Optimize video and stabilize it a little bit... still not perfect.
+ - Rewrite stream and file decoding API, as well as file format detection.
+ - Enhance shutdown and error message reporting, notably for icecast
+ and request-based sources.
+ - Avoid quasi-infinite loop in failed request resolving.

.SH DESCRIPTION
-.B liquidsoap
-is an extensible and flexible audio stream generator, mainly used for
-streaming to a shoutcast/icecast server. It is also possible to output in a
-file, to speakers or as raw PCM stream.
-.BR liquidsoap
-can perform any audio processing, mixing streams together, applying filters,
-generating sound procedurally, there is no limit but your imagination.
-Input files can be accessed through the network, using samba, ftp or speech
-synthesis.
-Recognized formats are MP3, Ogg/Vorbis, AAC and WAV.
-Liquidsoap also inputs HTTP streams, or from a soundcard.
-The system features lots of programming operators, including user requests,
-time-based selection, sum.
-Many of these features are optional, so it is possible that they are
-not enabled in your installation.
+.B Liquidsoap
+is a programming language for describing multimedia streaming systems.
+It is very flexible, making simple things simple but giving a lot
+of control for advanced uses.
+.B Liquidsoap
+supports audio, video and MIDI streams,
+and a wide range of input/output operators
+including Icecast and various soundcard APIs.
+It can perform a broad range of signal processing,
+combine streams in various ways, support custom transitions,
+generate sound procedurally...
+and all this can be assembled as you wish.
+Input files can be accessed remotely, or even be synthesized on the fly
+using external scripts such as speech synthesis.
+Finally, interaction with a running liquidsoap instance is possible
+via telnet or socket.
