There + is now also the option to let a filter-chain drain so that long filters + such as reverbs can fade out properly. + - Stability and compatibility improvements in JACK apps. + - Better Bluetooth compatibility with more devices. + - libcamera plugin improvements. + - Many bugfixes and improvements all over the map. + + +## PipeWire + - Fix compilation on ARM. + - Log topics are added to most modules. + - Documentation updates. Many improvements to the layout. Reorganisation + of the modules and groups. + - Share a work queue for all links and nodes. This removes the need for + a separate eventfd per link and per node. + - Catch errors in the map implementation. + - Add option to compile without dbus support. + - Fix biquad frequency. It was using the wrong sample rate. + - Fix a potential crash when destroying nodes, in some cases the node + would not be deactivated properly. + - Add some more helpers for dealing with properties and their values. + - Implement flush and reset on virtual sinks/sources. + - Make it possible to let virtual sinks/filter-chains run and drain + after being idle. + - Fix a bug where the quantum could exceed the maximum because it was + scaled with the sample rate. + - Fix channel_map parsing in module-zeroconf-discover so that the remote + channel map is used. + - pw-stream errors emitted on the proxy are reported but not fatal + any more. They are usually used by the session manager to signal status + to the client but otherwise does not really cause an error on the + client. + - Links now also store the output and input node id in the global + properties so that applications can parse and use them regardless of + how the link was made. (#1723) + - pw-stream and pw-filter now have an event to notify commands. + - The echo-cancel module can now operate on larger quantums. + - pw-cat now uses the right metadata to find the default devices in + --list-targets. + +## media-session + - Don't try to remix unpositioned streams when linking. This ensures + that linking to Pro-Audio nodes does not remix the stream channels + but links them as they are, one by one. + - media-session is now moved to a separate module to accelerate its + deprecation in favour of WirePlumber. + +## SPA + - Many libcamera improvements, handle MemFd buffers, handle errors + gracefully. + - Small improvements to make interface fall-backs easier to implement. + - Add support to enable flush-to-zero and denormals-are-zero to avoid + high CPU usage when dealing with denormals. + - AUX13 channels are no longer reported as AUX12. (#1727) + - Devices with more than 32 channels in Pro-Audio mode now only + uses AUX channels. + - Improve windowing function of the resampler to reduce aliasing and + improve the quality. + +## JACK + - Port connect callbacks will not only be emitted after the port + has negotiated buffers, which improves compatibility with + applications that try to use the port right after the callback + (jack_midi_latency_test). + - Fix crash when midi ports were removed and being monitored, like + in Ardour. + +## pulse-server + - The pulse tunnel will now use the specified format/rate/channels. + - Improve lookup of default source and fall back to the monitors when + no sources are available. + - Mark some nodes as network nodes so that we can set the NETWORK flag + correctly. + +## GStreamer + - The GStreamer element not releases the buffers in the stream again in + all cases so that they can be reused by other streams. + +## v4l2 + - Add a v4l2 LD_PRELOAD library to emulate v4l2 system calls on top of + PipeWire. This is tested with firefox and GStreamer and is known to + not work with Chrome. + +## Bluetooth + - AAC compatibility improvements. + - Disable hardware volume for "Tribit MAXSound Plus" and + "SoundCore mini". + - Add quirk to disable faststream. Disable faststream on "FiiO BTR3". + - Add a dummy AVRCP player to improve compatibility with some devices. + + +Older versions: + + # PipeWire 0.3.38 (2021-09-30) This is a quick bugfix release that is API and ABI compatible @@ -42,9 +147,6 @@ with previous 0.3.x releases. - Make the service file require a session manager. -Older versions: - - # PipeWire 0.3.37 (2021-09-23) This is a quick bugfix release that is API and ABI compatible diff --git a/meson.build b/meson.build index f2370e4a9..7172ee4f5 100644 --- a/meson.build +++ b/meson.build @@ -1,5 +1,5 @@ project('pipewire', ['c' ], - version : '0.3.38', + version : '0.3.39', license : [ 'MIT', 'LGPL-2.1-or-later', 'GPL-2.0-only' ], meson_version : '>= 0.54.0', default_options : [ 'warning_level=3',
