# PipeWire 0.3.70 (2023-04-20)

This is a quick bugfix release that is API and ABI compatible with previous 0.3.x releases.

## Highlights

• Fix a regression in the scheduler that could keep some nodes IDLE.
• Fix a regression in the biquad filters in filter-chain.
• Fix a regression and potential crash in the ALSA mixer probing.
• Fix a regression in pipewiresrc with timestamps that could cause cheese to record video with wrong timestamps.
• Beamforming support was enabled in the echo-canceler.
• pulse-tunnel and raop-sink will now proxy local volume changes to the remote end.
• More bugfixes and improvements.

## PipeWire

• Fix a bug in the graph scheduler where some nodes might stay IDLE in some cases (like when connecting the source of the echo-canceler to the sink).
• pw-metadata can now be created from the factory with initial values for the metadata.
• Conditions were added to the pipewire config file to make it possible to configure the access module and the exec sections.
• Support was added in pw-stream to intercept and override properties for the adapter. This can be used to implement custom volume control, for example.

## Tools

• pw-metadata can now list all available metadata objects with the -l option.
• A new pw-config tool was added to debug configuration file loading and parsing.

## Modules

• The webrtc echo canceler now supports beamforming. You can provide the coordinates of the microphones and let webrtc perform beamforming on the captured samples to improve quality and remove noise.
• Fix a regression in the filter-chain with biquad filters and improve error reporting.
• The pulse-tunnel will now proxy the volume changes to the remote end.
• The RAOP sink will now send volume parameters to control the volume remotely.

## SPA

• One ALSA commit was not correctly reverted and might cause crashes.
• The ALSA sink and source now calculate the ALSA ringbuffer memory location more correctly wich might improve compatibility with some hardware.
• v4l2 now sets the values of the controls in the Props param.

## Pulse-server

• The echo-canceler aec_args are now parsed like they would be under pulseaudio.

## Bluetooth

• More work on synchronizing BAP devices.

## GStreamer

• The GStreamer source can now renegotiate the format when it changes.
• The GStreamer source now uses the BaseSrc clocking code to implement the clock and timing code.
