+0.?.? (to be announced) "volatile relativity"
+---------------------------------------------
+
+--------------------------------------
+0.4.11 (2012-07-20) "mutual diversity"
+--------------------------------------
+
+The major feature in this release is the new sideband API for
+client-server communication. This API will be used exclusively starting
+with 0.5.0, which breaks backward compatibility but allows to get rid
+of quite some compatibility code. Other noteworthy changes include
+decoder latency improvements and a long-standing bug fix for the
+ALSA writer.
+
+ - Sideband connections: If both para_server and para_client
+ support this feature, data is sent as a multiplexed stream.
+ - The --no_default_filters option of para_filter has been
+ removed.
+ - Several fixes and latency improvements to various decoders.
+ - The ALSA writer now limits the prebuffer time to 500ms.
+ - Documentation improvements.
+ - Overhaul of the command_util.sh script.
+ - Fixes for some minor problems found by the clang analyzer.
+ - Compiles (almost) without warnings on gcc-3.
+ - Robustness improvements of the buffer tree code.
+
+------------------------------------------
+0.4.10 (2012-03-30) "heterogeneous vacuum"
+------------------------------------------
+
+Nothing earth-shaking in this release, but quite a few usability
+improvements and the usual mix of cleanups and fixes.
+
+ - The --no_default_filters option of para_filter has been
+ deprecated. It still works but has no effect and will be
+ removed in the next version.
+ - para_gui now prints also the stderr output of the executing
+ command in the bottom window.
+ - Cleanup and consolidation of the various wrappers for
+ write(), writev(), send() and friends.
+ - The obscure error messages on mmap() failures have been
+ replaced by meaningful messages. This affects mainly
+ para_afh.
+ - para_audioc: Cleanups and memory leak fixes.
+ - Test 0004-server no longer fails if para_server is not
+ being built.
+ - New configure options: --with-id3tag-{headers,libs}.
+
+-------------------------------------
+0.4.9 (2011-12-06) "hybrid causality"
+-------------------------------------
+
+Support for another audio format, interactive mode for para_client
+and para_audiod and many small improvements/fixes all over the place.
+
+ - Support for flac, the free lossless audio codec.
+ - Fix for an endless loop in the mp3 decoder for certain
+ (corrupt) mp3 files.
+ - When executed without specifying a command, para_client
+ and para_audioc start an interactive shell (requires
+ libreadline being installed). The interactive mode offers
+ full tab completion and command line history.
+ - autogen.sh now detects a distcc setup and adjusts the
+ parameter for the -j option of make accordingly.
+ - Shared memory areas are no longer restricted to 64K. We now
+ detect the maximal size of a shared memory area at runtime.
+ - cleanup of the internal uptime API.
+ - para_server prefaults the mmapped audio file to avoid
+ delays on slow media.
+ - A new test for the test-suite that exercises the
+ communication between para_server and para_audiod.
+ - The alsa writer eats up less CPU cycles when configured to
+ use the DMIX plugin.
+ - Simplified and unified receiver code.
+ - Makefile cleanups.
+ - Commands which print a list of matching audio files now
+ emit a meaningful error message if no audio file matched the
+ given pattern(s).
+
+--------------------------------------
+0.4.8 (2011-08-19) "nested assignment"
+--------------------------------------
+
+Gcrypt support, the overhauled osx writer and regex format specifiers
+are the highlights of this release.
+
+ - support for libgcrypt as a drop-in replacement for openssl.
+ Run configure --enable-cryptolib=gcrypt to link against
+ libgcrypt. The two crypto implementations are compatible to
+ each other, i.e. a para_client executable linked against
+ gcrypt can connect to para_server linked against libssl
+ and vice versa.
+ - Rewrite of the osx writer (output plugin for Mac OS).
+ - audiod: The format specifier for receivers, filters and
+ writers is now treated as a regular expression. This allows
+ to replace 5 lines in the config file (one for each audio
+ format) by one single line. See the manual for details.
+ - The *.cmdline.[ch] files are no longer contained in the released
+ tarballs. This reduces the size of the tarballs but requires
+ gengetopt to build the tarball.
+ - Compiles cleanly also with llvm/clang.
+ - Corrupt mp3 files are handled more gracefully.
+ - The alsa writer uses poll fds instead of computing timeouts.
+ - Cleanup of the generic writer API.
+ - sched: Optimized zero timeouts.
+ - vss timeout cleanups.
+ - oggdec fixes and improvements.
+
+--------------------------------------
+0.4.7 (2011-06-01) "infinite rollback"
+--------------------------------------
+
+The new ao writer, support for ssh RSA keys and a couple of other
+enhancements.
+
+ - Support for ESD, Pulseaudio, AIX, Solaris, IRIX and other
+ platforms through the libao audio library.
+ - Support for RSA keys generated with ssh-keygen.
+ - configure: improved options for ogg/vorbis/speex.
+ - The git version reported by --version always matches HEAD.
+ - The autogen script detects the number of processors and
+ runs a parallel make if possible.
+ - Major cleanup of the crypto API.
+ - Documentation updates.
+
+------------------------------------------
+0.4.6 (2011-03-31) "deterministic entropy"
+------------------------------------------
+
+Lots of ogg/vorbis improvements, the new test suite, enhancements
+for para_gui and a fair amount of other bug fixes.
+
+ - For DCCP/OGG streams the audio file header is only sent once
+ at the beginning of the stream rather than periodically
+ every five seconds. This reduces network traffic and the
+ FEC group size.
+ - The vorbis comment header is replaced by an empty dummy header
+ before the header is sent over the network. This also results in
+ less network traffic and smaller FEC groups.
+ - The new "test" make target allows to perform some sanity checks prior
+ to installing the package.
+ - ogg timing fixes and performance improvements
+ - Scheduler improvements
+ - Proper exit codes for para_write
+ - para_gui: New option --theme to select a startup theme. Several
+ other improvements and fixes.
+ - aacdec error message cleanups
+ - simplified color error handling
+
+--------------------------------------------
+0.4.5 (2010-12-17) "symmetric randomization"
+--------------------------------------------
+
+Bug fixes, internal cleanups and variable-sized FEC slices.
+
+ - Contains a fix for an invalid-free-bug in the ogg audio format
+ handler code.
+ - Switching off the DCCP sender works again.
+ - para_audiod handles crashes of para_server more robustly.
+ - Internal scheduler and writer cleanups.
+ - Reduced latency due to variable-sized FEC slices.
+ - Improved documentation and error diagnostics.
+ - The build of para_server is now optional, allowing the build
+ to succeed in case libosl is not installed.
