Other user-visible changes include minor +additions to the "ls" and "select" server commands. The release also +includes a fair number of cleanups for the crypto code and the file +descriptor utilities, both without visible effects. Old ssh keys +and outdated openssl library versions are now deprecated and cause +warnings. + +- Old style PEM keys are now deprecated. They still work but their + use results in a run-time warning.

When invoked like --admissible=m/foo, only files which are + admissible with respect to mood foo are listed. +- The select server command is now quiet by default, The new --verbose + option can be used to show information about the newly loaded mood + or playlist. +- The ls server command gained the --limit option to force a limit + on the number of files listed. +- Cleanup of the openssl-specific code. + +Downloads: +[tarball](./releases/paraslash-0.7.3.tar.xz), +[signature](./releases/paraslash-0.7.3.tar.xz.asc) + +------------------------------------- +0.7.2 (2023-03-08) "optical friction" +------------------------------------- + +The improved error reporting of afs commands and the two new options +for the sleep subcommand of para_mixer are the most prominent features +of this minor release. The bulk of the changes are cleanups of the +afs and net subsystems, which should both have no user-visible impact. + +- A major cleanup of the audio file selector. +- The client no longer prints error messages from afs commands to + stdout but to stderr. +- The sleep subcommand of para_mixer gained two options to control + the startup mood and the time period before fade-out starts. A bunch + of further improvements for this subcommand went in as well. +- Minor cleanup of the net subsystem. +- The openssl specific code now employs the EVP API to compute hashes. + It should compile without warnings against openssl-3. +- The deprecated syntax for specifying negative offsets in the argument + to the "ff" server command has been removed. + +Downloads: +[tarball](./releases/paraslash-0.7.2.tar.xz), +[signature](./releases/paraslash-0.7.2.tar.xz.asc) + +-------------------------------------- +0.7.1 (2022-10-03) "digital spindrift" +-------------------------------------- + +The two new ll commands and the internal mp4ff library are the most +user-visible changes of this release. On top of that there are two +core changes which aim to improve the robustness of the code but which +are otherwise invisible: the switch from select(2) to poll(2) and the +revised memory allocation API which checks for integer overflows. The +release also comes with a slight change to the build system and the +usual mix of bug fixes and minor improvements not mentioned here. + +- The autogen.sh script now only creates the autoconf specific files + but no longer runs configure, make and the test suite. +- A stripped down copy of the discontinued libmp4ff library has become + part of the paraslash code base. As a result it is no longer necessary + to install faad from source to get support for aac/m4a files. The + faad decoder package must still be installed. +- The log level of the running daemon can now be changed with the + new ll command. It is available for para_server and para_audiod. +- All calls to select(2) have been replaced by calls to poll(2) + to avoid known shortcomings of the select API. +- All allocation functions now check for integer overflow. Since this + requires support from the compiler, the oldest supported gcc version + has been bumped to gcc-5.4 (released in 2015). + +Downloads: +[tarball](./releases/paraslash-0.7.1.tar.xz), +[signature](./releases/paraslash-0.7.1.tar.xz.asc) + +---------------------------------- +0.7.0 (2022-03-12) "seismic orbit" +---------------------------------- + +The major incompatible change which requires to bump the major version +is the switch from sha1 to sha256, see below for details. However, +there are many other improvements, the usual amount of bug fixes and +a couple of new features. + +- Starting with paraslash-0.7.0, the sha256 hash value of each known + audio file is stored in the database while older versions employed the + sha1 hash algorithm which has been considered insecure since 2005 + and should no longer be used today. The switch from sha1 to sha256 + requires users to upgrade their database using the new para_upgrade_db + program, followed by re-adding all files to recompute the hashes. With + this approach all metadata stored in the database (last played date, + num played value, moods, playlists, attributes etc.) are kept. An + simpler alternative is to start over from scratch by running the + "init" command but this will lose these metadata. +- Server and client now hash the session keys with sha256 rather + than sha1 during the initial handshake. This feature is optional and + backwards compatible: old clients can still connect to a new server + (using sha1). Also new clients can connect to an old server (again + using sha1). +- The new "duration" keyword of the mood grammar makes it possible to + impose a constraint on the duration of the admissible files. +- The long deprecated version 1 mood syntax is no longer supported. +- Paraslash writers handle early end-of-file more gracefully. +- The alsa writer no longer warns about spurious underruns. +- The score formula of the audio file selector has been reworked. +- Cleanups of the doubly linked lists code. +- New option for configure: --enable-ubsan to detect and report undefined + behaviour. +- The "tasks" server command has been removed. +- The fancy new logo and a minor overhaul of the web pages. + +Downloads: +[tarball](./releases/paraslash-0.7.0.tar.xz), +[signature](./releases/paraslash-0.7.0.tar.xz.asc) + +-------------------------------------- +0.6.4 (2021-11-04) "fuzzy calibration" +-------------------------------------- + +This point release contains a fair number of fixes but no new features. +This marks the end of the 0.6 development, although paraslash-0.6 will +still be supported for some time and subsequent maintenance releases +may follow. + +- The udp sender no longer crashes when empty chunks are encountered. +- Fix a double-free bug in the exit path of the server. +- The "jmp" command now errors out when given a negative percentage. +- A fix for a bug in para_afh which triggered on the attempt to modify + the tags of an invalid mp4 file. +- A memory leak in para_afh has been fixed. +- The udp sender no longer sends multiple EOF packets. +- Some gcc warnings have been silenced. +- Minor log level adjustments and documentation improvements. + +Downloads: +[tarball](./releases/paraslash-0.6.4.tar.xz), +[signature](./releases/paraslash-0.6.4.tar.xz.asc) + +--------------------------------------- +0.5.9 (2021-11-04) "reversed dimension" +--------------------------------------- + +This release contains a few important fixes which have accumulated in +the maint branch. The paraslash-0.5.x series has now reached its end +of life and will no longer be supported.

It contains a fair number of improvements, +features and fixes all over the place. + +- The ff command now accepts a negative argument to instruct the + virtual streaming system to jump backwards in the current audio + stream. The old syntax (e.g., "ff 30-") is still supported but it + is deprecated and no longer documented. The compatibility code is + sheduled for removal after 0.7.0. +- para_afh: New option: --preserve to reset the modification time to + the value of the original file after meta data modification. +- Overhaul of the compress filter code. The refined algorithm should + reduce clipping. The meaning of --aggressiveness has changed, see the + updated and extended documentation of the compress filter for details. +- Cleanup of the audio format handler code. +- We now build the tree using the .ONESHELL feature of GNU make, + which results in a significant speedup. +- Two robustness fixes for FreeBSD. +- para_client now supports RFC4716 private keys as generated with + ssh-keygen -m RFC4716. In fact, this key format has been made the + default, and the former PEM keys will be depreciated at some point. +- The ogg audio format handlers learned to detect holes and now report + the correct duration also if ogg pages are missing in the file. This + affects ogg/vorbis ogg/speex and ogg/opus. +- Robustness improvements for para_mixer. +- A fix for an old bug that could cause the server to crash or report + garbage in its status output. +- New para_play option: --end-of-playlist +- Streaming m4a files over udp has been improved. + +Downloads: +[tarball](./releases/paraslash-0.6.3.tar.xz), +[signature](./releases/paraslash-0.6.3.tar.xz.asc) + +-------------------------------------- +0.6.2 (2018-06-30) "elastic diversity" +-------------------------------------- + +The main new feature of this release is the --listen-address option +for para_server and para_audiod. But there are also a large number of +small improvements and bug fixes all over the place. The user-visible +changes include + +- para_gui no longer waits up to one second to update the screen when + the geometry of the terminal changes. +- Minor documentation improvements. +- Improvements to the crypto subsystem. +- The server subcommand "task" has been deprecated. It still works, + but prints nothing. It will be removed in the next major release. +- Server log output is now serialized, avoiding issues with partial + lines. +- It is now possible to switch to a different afs database by changing + the server configuration and sending SIGHUP to the server process. +- New server options: --listen--address, --http-listen-address and + --dccp-listen-address. These options restrict the set of listening + addresses of the TCP and DCCP sockets of the server process. +- The help commands of server, audiod, play now support --long. By default, + the short help is shown. +- The code which merges the command line options with the config file + options has been consolidated. +- If the current audio file is renamed, the status items are now updated + accordingly. +- After the server process received SIGHUP, changes to the current audio + file did not trigger an update of the status items. This has been fixed. + +Downloads: +[tarball](./releases/paraslash-0.6.2.tar.xz), +[signature](./releases/paraslash-0.6.2.tar.xz.asc) + +---------------------------------------- +0.6.1 (2017-09-23) "segmented iteration" +---------------------------------------- + +The highlight of this release is the version 2 mood parser. But there +is a lot more than that, as summarized in the list below. And of +course we have many small usability improvements and bug fixes not +mentioned here. + +- A more intuitive syntax for moods ("version 2 moods"). The + traditional version 1 moods are still supported but are deprecated + now. Removal of the version 1 mood parser is scheduled for the next + major release. +- Flex and bison are now required to build para_server. - New sort order for the ls command: -s=h sorts the ls output by hash value of the audio file. - autogen.sh now runs the test suite after a successful build. - The contents of overview.pdf have been integrated into the user manual. +- Fixed sized audio format headers for ogg/opus streams. - The doxygen source browser has been disabled temporarily. The API reference is still online, though. - Overhaul of the source code documentation. @@ -16,6 +277,44 @@ current master branch removed. It was a no-op since 0.6.0. - The wma decoder has been cleaned up and its bitstream API made more robust. +- The image/lyrics ID status items of the current audio file are now + updated on changes.
