# PipeWire 0.3.31 (2021-06-28)
This is a bugfix release that is API and ABI compatible
with previous 0.3.x releases.
## Highlights
- Fixes for alsa-lib 1.2.5
- New pulseaudio modules: module-avahi-zeroconf,
module-pipe-source, module-roc-sink, module-roc-source
- JACK has seen massive stability improvements. Locking
and correctness wrt to callbacks and has been reworked. Also
thread priorities have improved.
- Handle various crashes and lockups when running out of file
- Bluetooth now uses a hardware database to disable
non-working features on listed devices.
- Scheduling quantum and rate can now be changed dynamically
with pw-metadata.
- Many bugfixes and improvements.
## PipeWire
- Improve cleanup of context in error cases.
- There is now a pw-test framework for improved unit tests.
- Improve property serialization to valid JSON.
- Fix some macros to work with better with coverity.
- Metadata permissions are checked now. Clients need the
M permission on an object to be able to set metadata for
- The core metadata object will now remove metadata for
removed objects, the implementor does not need to worry
about that anymore.
- Audioadapter will now follow the rate of the graph with
the resampler adjusting itself dynamically.
- Core now has a metadata implementation helper. A context
will expose a metadata with settings that can be changed
at runtime. This can be used to change the lowlevel or
graph quantum and samplerate on the fly.
- An infinite loop was fixed in the audio converter.
- Handle out-of-fds more gracefully. Handle truncated
control data by dropping the client connection.
- Fix profiler crash with many streams.
- Improve latency handling in pw-filter. There is now a
default handler and a ProcessLatency parameter to simplify
latency reporting.
- Latency reporting was improved in devices and streams.
- And example sink/source was added.
- hardware mute and volume are now properties on the
Route param to make things easier.
- More fixes for alsa-ucm 1.2.5.
## Tools
- spa-json-dump now properly encodes string and keys
- pw-dump now shows the correct subject of the metadata.
## PulseAudio server
- Ensure the node.description is set, some applications
crash otherwise (TeamSpeak).
- Module loading and unloading was improved.
- module-avahi-zeroconf was implemented.
- module-pipe-source was implemented
- module-roc-sink and module-roc-source was implemented
- The maximum amount of connections has been limited to 64,
like pulseaudio.
- Handle out-of-fds more gracefully.
- Fix overflow of read/write pointers.
- source and sink state are now decoupled from the monitor
state and will report IDLE when not playing anything.
## media-session
- Port switching should now happen to/from the port that
actually changed.
- The locking was reviewed. All callbacks are not emited
from the PipeWire thread with the lock released and
the process function will be disabled for the duration
of the callback. This ensures that no two callbacks are
called at the same time.
- Improve internal consistency and try to never call callbacks
with invalid objects.
- Monitor port can now be accessed with system:monitor_%d
- client threads are now created with SCHED_FIFO and module-rt
is used to create the other RT threads. This should avoid
SIGKILL from RTKit in some cases.
## Bluetooth
- Various bugfixes to improve connections to devices.
- Handle delayed UUID connection.
- There is now a hardware database that can disable features
in listed devices.
- Use libusb to detect availability of mSBC.
- The virtual device name can now also contain a media role.
