(to be announced) "spectral gravity" +------------------------------------------ + + - UTF8 support for para_gui and the mp3 audio format handler. + - Scheduler improvements and fixes. + - The obsolete gettimeofday() function has been replaced + by clock_gettime() on systems which support it. + - Speed and usability improvements for para_gui. + - para_client now restores the fd flags of stdin and stdout + on shutdown. + - Improved manual pages. + - Consistent version strings for all executables. + - Reduced depencies on generated files result in fewer + recompilations on changes. + - Performance improvements for the compress filter. + - Improved downloads web page. + +----------------------------------------- +0.4.12 (2012-12-20) "volatile relativity" +----------------------------------------- +The new command line player, the resample filter, ALSA support for +para_fade, and the improved build system are the highlights of this +release which probably marks the end of the 0.4.x series. + + - The afh receiver and the para_play executable. + - The resample filter: A sample rate converter based on + libsamplerate. + - The "versions" directory has been removed from the master + branch. The tarballs of the old releases are now available + in the new "releases" branch. + - Overhaul of the build system: All generated files are now + written to the "build" directory. + - The modular mixer API and the alsa mixer. + - Minor fixes for the osx writer. + +-------------------------------------- +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. ---------------------------------------------------- -0.4.0 (to be announced) "simultaneous independence" ---------------------------------------------------- +------------------------------------------ +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. + +------------------------------------------ +0.4.4 (2010-08-06) "persistent regularity" +------------------------------------------ + +Support for yet another audio format, para_write improvements and +bug fixes. + + - Support for the speex codec. + - Support for sample formats other than 16 bit little endian. + - error2.h is now created by a perl script which speeds up configure + considerably. + - Fix a bug in the aac decoder which could lead to segfaults in + para_filter/para_audiod. + - Fixes for autoconf-2.66. + +---------------------------------------- +0.4.3 (2010-07-05) "imaginary radiation" +---------------------------------------- + +Many improvements for the DCCP and the UDP transport, the new user +manual and the usual mix of bug fixes and internal improvements. + + - FEC support for the DCCP sender (Gerrit Renker). The new + --dccp_max_slice_size, --dccp_data_slices_per_group and + --dccp_slices_per_group options can be used to set the FEC + parameters for the DCCP transport. + - DNS lookups for UDP targets (Gerrit Renker). + - The new user manual replaces the README, README.afs, REQUIREMENTS + and INSTALL documents. + - Fix an end-of-file detection bug in the oggdec filter. + - The new nonblock API. + - Both options of the oggdec filter have been removed. + - New debug mode for the internal scheduler. + +------------------------------------------ +0.4.2 (2010-04-23) "associative expansion" +------------------------------------------ + +It's been some time since the last release, but finally here is +paraslash-0.4.2. The bulk of the changes comes from the new buffer +tree API, but there are changes all over the tree. Mainly performance +and usability improvements, but also quite some bug fixes. + + - The new buffer tree API. + - DCCP: Support for CCID negotiation (Gerrit Renker). + - UDP robustness fixes. + - The --bufsize option for mp3dec is gone as it no longer makes sense + for the new buffer tree API. + - Fix audible buffer underruns for wma streams. + - The alsa writer no longer prints meaningless underrun durations. + - audiod: Defaults work also for udp streams. If no filter is + given for an audio format that is received via upd, fecdec is + automatically added as the first filter (along with the decoder). + +--------------------------------------- +0.4.1 (2009-12-22) "concurrent horizon" +--------------------------------------- + +Support for another audio format, minor feature enhancements and lots of bug +fixes. All fixes that have been accumulated in the maint branch (in particular +those mentionened in the 0.3.6 release notes) appear in this release as well. + + - wma support. + - new afh option: --human to activate human-readable output. + - new server/audiod option: --log-timing to print timing information. + - build system improvements. + - source code documentation updates. + +------------------------------------- +0.3.6 (2009-12-07) "cubic continuity" +------------------------------------- + +Quite a few bugs have been found and fixed since 0.3.5, so here's +another 0.3.x release.
