+
+0.3.7 (03-06-2008)
+Bugs fixed:
+ - Now works on FreeBSD and hopefully other unices that are stricter than
+   Linux about Mutex usage.
+ - input.http() now has a bind_address parameter.
+ - Harbor socket now has a timeout for lost connections.
+ - smartcross() is now more compliant with the inter-sources protocol,
+   fixes several "get frame didn't change the buffer" bugs.
+ - Ogg packeting bugs.
+ - Buffering policy in input.http/harbor().
+ - No "." in IDs and labels.
+ - Resources: FD leaks, useless threads (threads leaks?) in input.http().
+ - fade.out() used to run into infinite loops when the delay was 0.
+New:
+ - New documentation system and website.
+ - Self-documenting server with a more helpful "help" command.
+ - Moved to duppy: less threads, lighter load, and an configurable scheduler.
+ - Moved to Taglib for more reliable access to MP3 metadata.
+ - MIME types, notably for playlists and MP3 files.
+ - New Jack support. The old one has been renamed to in/output.jack.legacy().
+ - Harbor: per-mount passwords and the stop command to kick a source client.
+ - Official Last.FM client.
+ - Metadata is no more punctual but interval-based, which suppresses some 
+   surprising behaviours.
+ - Perfected daemon behaviour.
+ - All output.file.*() now have the features that used to be only in 
+   output.file.vorbis(), notable re-opening. Added %w to the strftime-like 
+   format codes allowed in their filename parameter.
+ - Add clear_metadata() and map_metadata(). Now, rewrite_metadata() is a simple
+   specialization of map_metadata(), written in utils.liq.
+ - Dynamic amplification factor in amplify(), e.g. useful for replay gain.
+ - Lots of new functions in the scripting API: for lists, requests, system 
+   interaction, shutdown, command-line parsing, scripted server commands, etc.
+As always:
+ - code cleanup, style, etc.
+

+
+0.3.4 (25-09-2007)
+Notation: "-" stands for a change, "+" for an addition.
+* Language
+  - Support for polymorphism, subtyping and basic ad-hoc polymorphism,
+    which allows a much simpler API, notably for maths and serialization.
+  + Added interactive_*() for mutable values.
+  - The right syntax for settings is now set("var", value) and can be used
+    anywhere in the scripts.
+  - The volume parameters of most operators are now in dB.
+  - Many builtin functions added.
+  - Nicer type error messages.
+* Sources
+  + Added input.lastfm() to relay last.fm streams.
+  + Added input.harbor() to received Icecast2 source streams.
+  + Added noise() to generate white noise
+  - Reimplemented playlist support, added various xml and text formats.
+  - Added mpd protocol to find files using mpd.
+* Operators
+  + New effects: compress(), flanger(), pan().
+  + New filters: filter.fir.*(), filter.iir.*(), filter.biquad.*(), comb().
+  + Added support for LADSPA effects.
+  + Added eat_blank() to remove blanks.
+* Outputs
+  - Added non-default restart option for output.icecast.*().
+  - Added the possibility to tweak some settings at runtime.
+  - Split output.icecast.vorbis() into output.icecast.vorbis.*() to distinguish
+    between encoding modes -- and similarly for output.file.vorbis and mp3.
+  - Better handling of Icecast disconnections.
+* IO
+  + Added portaudio support.
+  - Jack support is now somewhat working.
+* As usual, lots of bug fixes, careful polishing & much more...
+
+0.3.3 (06-06-2007)
+* Major cleanup of the core stream representation; moved to float arrays,
+  removing several back-and-forth conversions and enhancing the perfs a lot;
+  reviewed all sources and operators, made many minor enhancements btw.
+* Lots of sound processing operators: compand, compress, normalize,
+  pitch, bpm, soundtouch, saw, square, etc. Add more shapes to fade.*().
+* New track processing operators: insert_metadata, on_track.
+* Smart cross: allows to select a transition based on the volumes around the 
+  end-of-track.
+* Support for AAC encoding/decoding.
+* Several fixes to output.icecast.mp3 in order to support shoutcast servers.
+* Automatic format recognition for input.http(), support for playlists.
+* OSS I/O.
+* Unbuffered ALSA I/O for low latency.
+* Server interface via UNIX domain sockets.
+* Better output.file.vorbis with support for re-opening the file, appending,
+  interpolate strftime format codes, etc.
+* Add pre-processing and math primitives to the language, new _[_] notation for 
+  assoc(), ruby-style anti-quotation ("..#{..}.."), add_timeout(), execute(),
+  log()...
+* Ability to tweak the internal PCM stream format.
+* Classify sources and operators in categories for more structured doc.
+* Started a few visualization operators, text and graphics based.
+* Several bug fixes: request leaks, sine frequency, switch, etc.
+
+0.3.2 (16-03-2007)
+* New portable output to speakers using libao().
+* Updated liGuidsoap to use it until ALSA gets enhanced.
+* Implemented a decent estimation of the remaining time in a track.
+* Added the cross() operator allowing cross-fading.
+* Generalized say_metadata() into append() and prepend().
+* Per-track settings for cross(), fade.*(), prepend() and append()
+  using requests' metadatas.
+* Implemented input.http.mp3(), including support for icy metadata.
+* New pipe() operator which allows one to filter the raw audio through an 
+  external program. However, sox and other common tools aren't suitable for that
+  because they don't flush their output often enough.
+* New on_blank() operator for calling a callback on excessive blanks.
+* Restart outputs on insane latencies.
+* Type checkings for settings.
+* Setting for not starting the internal telnet server.
+* Now handles old and new versions of Camomile correctly.
+* Internal fixes and polishing (switches' cached selection, empty tracks..)
+
+0.3.1 (17-11-2006)
+* More standards-compliant tarball
+* Generate doc with locally built liquidsoap
+* Try to cope with ill-formed mp3
+* Updated for newer versions of Camomile
+* So-called "strict" random-mode
+
+0.3.0 (27-08-2006)
+* Many minor and major fixes at every level!
+* Conversion of metadata to UTF8.
+* Got rid of too many threads by scheduling all download tasks
+  in a single thread, and handling all of the server's clients
+  in another single thread.
+* Simplified the time interval syntax and integrated it to the script language.
+* New protocol: Wget for FTP, HTTP and HTTPS.
+* Ability to define a new protocol from the script,
+  typically using an external app/script for resolution, such as bubble.
+* Ability to use an external app/script for dynamically creating requests.
+* New on_metadata operator for performing arbitrary actions (typically
+  a call to an external script) when metadata packets occur in a stream.
+* MP3 encoding, to file or shout.
+* API renamings and simplification.
+* Supports transition, as functions of type (source,source) -> source
+  in all switching operators: schedule, random, fallback.
+* Restart icecast2 outputs on failures.
+* Major changes to the scripting language which is more uniform and flexible,
+  has functions, a helpful (?) type inference, and a simple Ruby-like syntax.
+* Timing constraints and synchronization are managed by Root
+  in a centralized way, no more by the many outputs which need it.
+* Audio decoding is no more based on file extensions,
+  but on the existence of a valid decoder.
+* Added the equeue operators which allows interactive building of playlists,
+  supporting insertion and moving of queued requests -- queue only allows
+  you to push requests and cancel queued requests.
+* A Python-Gtk GUI for controlling operators, or more specifically as a console
+  for creating your live show -- to be updated, still unstable.
+* Alsa input and output.
+* Blank detection, automatically skips on too long blanks, or strip them.
+* Http ogg/vorbis relay, the way to relay live shows.
+* Interactive mixer.
+* The request system was mostly rewritten to really fulfill its specification.
+* The server is no more associated to the queue operator but is now something
+  external, in which all operators can plug commands. This much more logical
+  design lead to many more interactive controls. The syntax of command outputs
+  was also simplified for easier automated processing.
+* Dynamic loading of plugins.
+* Outputs are now operators. It makes it possible to output different streams
+  in a single instance of Liquidsoap, which RadioPi needed. As a consequence
+  we removed the restriction that one source must have at most one father,
+  without any extra burden for the user.
+
+0.2.0 (20-04-2005)
+* Proper initial release.
+
+0.1.0 (2004)
+* Release for academic demonstration, not functionnal.
