It also includes a +fair number of smaller fixes and improvements not mentioned here. + + - The new sync filter synchronizes playback between multiple + clients. + - Connections between para_server and para_client are now + encrypted by means of AES rather than RC4 if both sides + support it. RC4 is still available as a fallback. This + feature is fully transparent, i.e. no command line options + are necessary, and a client linked against openssl can + speak with a server linked against libgcrypt and vice versa. + - Major cleanup of the networking subsystem. + - Improvements to para_fade: the new set mode, multi-channel + initial volumes, better error logging. + - The man pages of para_audiod, para_filter, para_recv, and + para_write contain the relevant options for receivers, filters, + writers.

On systems without + openssl/gcrypt, the build succeeds but para_server, + para_audiod, para_client won't be built. + - The build system now works for cross-compile setups. + - The dependency tree has been flattened, which speeds up + builds and avoids to recreate the man pages on every change. + - The error code helper has been rewritten from perl to C, + which further improves build time. + - Many small bugs in the build system have been identified + and fixed. + +Downloads: ./releases/paraslash-0.5.1.tar.bz2 (tarball), +./releases/paraslash-0.5.1.tar.bz2.asc (signature) + +---------------------------------------- +0.5.0 (2013-08-23) "invertible validity" +---------------------------------------- + +Some API-breaking changes, one serious bug fix, and a lot of bike-shedding. + + - The sideband compatibility code has been removed, hence + sideband connections (introduced in 0.4.11) are now mandatory. + - Addblob commands can produce output. + - The stat command no longer sends garbage when para_server was + compiled against libgcrypt. + - Dependencies for gengetopt files are computed automatically. + This eliminates a constant source of build bugs. + - The setatt command now accepts file name patterns rather than only + path names. + - overview.pdf is now based on dia, a simple diagram creation program. + The new version is much more detailed and contains descriptions of + the various programs of the paraslash package. + - The separator of all multi-word options has been changed from + underscore to dash. For example --log_color becomes --log-color. + - Overhauled web pages and the new logo. + +Downloads: ./releases/paraslash-0.5.0.tar.bz2 (tarball), +./releases/paraslash-0.5.0.tar.bz2.asc (signature) + +-------------------------------------- +0.4.13 (2013-07-29) "spectral gravity" +-------------------------------------- + +One more 0.4.x release before the API-breaking changes for 0.5.0 go +in. The main features of this release are the ogg/opus audio format, +and UTF-8 support, but it includes also tons of other improvements +and fixes all over the place. + + - New audio format: ogg/opus. + - 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 dependencies 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. + +------------------------------------------ +0.4.6 (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" ---------------------------------------- @@ -345,7 +682,6 @@ A bunch of new features and core changes. - para_fade: wake time defaults to 8 hours from now - update to autoconf-2.60 - ------------------------------------------ 0.2.12 (2006-05-12) "oriented abstraction" ------------------------------------------ @@ -399,7 +735,6 @@ they are now called "audio file selectors" instead. - X86_64 fixes (thanks to Steffen Klassert) - para_play fixes - -------------------------------------- 0.2.10 (2006-02-17) "cyclic attractor" -------------------------------------- @@ -421,7 +756,6 @@ to the new source documentation. for para_recv/para_audiod as this information is now encoded in each rtp packet sent by para_server. - ------------------------------------------- 0.2.9 (2006-01-24) "progressive turbulence" ------------------------------------------- @@ -443,7 +777,6 @@ a lot of small improvements. - the new error subsystem gives better error diagnostics and reduces code size. - ----------------------------------------- 0.2.8 (2006-01-02) "dynamic accumulation" ----------------------------------------- @@ -458,7 +791,6 @@ The new modular filter design and the para_play-hangs bugfix. - para_play: fix a stupid bug that caused it to hang under certain circumstances. - ------------------------------------------- 0.2.7 (2006-12-27) "transparent invariance" ------------------------------------------- @@ -482,7 +814,6 @@ Not many user-visible changes but a fair amount of internal improvements. - use of gcc-extensions that #define away for non-gcc and gcc < 3.0. - ------------------------------------------- 0.2.6 (2005-10-29) "recursive compensation" ------------------------------------------- @@ -505,7 +836,6 @@ the internal find command and several other improvements and cleanups. - para_client code cleanup - para_gui: faster display of output of display commands - ------------------------------------------ 0.2.5 (2005-10-13) "aggressive resolution" ------------------------------------------ @@ -535,7 +865,6 @@ in parallel. - com_ne(): ignore errors on remove - audiod: fix segfault on server restart - --------------------------------------- 0.2.4 (2005-09-21) "toxic anticipation" --------------------------------------- @@ -557,7 +886,6 @@ Several small improvements, fixes and the new grab command. - server: report total size of memory allocated with sbrk by malloc, new command line option: --announce_time - ----------------------------------------- 0.2.3 (2005-09-01) "hydrophilic movement" ----------------------------------------- @@ -580,7 +908,6 @@ Two new executables and major feature enhancements. a local network to syncronize the audio output of all clients that play the same stream. - ------------------------------------------ 0.2.2 (2005-08-19) "tangential excitation" ------------------------------------------ @@ -601,7 +928,6 @@ for the mysql database tool.
