1.0.x releases.
## Highlights
- Fix a potential race/crash.
- Fix some problems with negotiation of large integers and floats.
- Fix JACK sysex MIDI event handling.
- Some more smaller fixes and improvements.
## PipeWire
- Fix a potential race when adding/removing a port to be scheduled.

# PipeWire 1.1.81 (2024-05-16)
This is the first 1.2 release candidate that is API and ABI
compatible with previous 1.0.x releases.
In addition to all the changes backported to 1.0.x, this release
also contains some new features:
## Highlights
- Support for asynchronous processing has been implemented. Nodes can choose
(or be forced) to be scheduled asynchronously. The graph will not wait for
the output of the node to continue processing but it will use the output
of the previous cycle (or silence) instead. This adds one cycle of latency
but it can avoid having some nodes blocking the processing graph. Non realtime
streams and filters now also use this asynchronous processing instead of
their own slightly broken version.
- The concept of node.sync-group was added. This groups nodes with overlapping
sync-group together when one of them sets the node.sync = true. This is now
used to make sure all nodes are scheduled together when JACK transport is
started so that they all see the same time.
- Config parsing errors are reported earlier and much better with line and
column numbers where the parsing started to fail.
- Add support for mandatory metadata when negotiation buffer parameters. This
can be used to only negotiate extra buffer planes when certain metadata is
negotiated. One use case is the explicit sync support that requires 2
extra fds for the timelines.
- Support was added for making and using multiple data-loops in the server
and clients. Support for CPU affinity and priorities was added to the
data-loops as well.
- The log topic debug levels can now be changed at runtime with metadata.
The log levels in the pulse server can be dynamically changed with a
/core message.
- The UCM conflicting devices patches were merged.
## PipeWire
- snap support has been added.
- Implement async processing. (#3509)
- Support for explicit sync was added.
- Config parsing errors are reported earlier and much better.
- A -P option was added to provide extra properties to the context. This can be
used to enable some features that use rules.
- properties.rules was added to enhance properties based on some rules.
This deprecates the vm.overrides.
- Support was added for security-context. This makes it possible for a flatpak
to request a socket with specific properties from pipewire to mount in the
flatpak. The session manager can then assign permissions based on the connection
properties.
- Support for fixed arrays in pw_array was improved.
- PipeWire server and clients can now use multiple threads to process the nodes
in parallel.
- device.rules and node.rules were added to update device and node properties
based on rules.
- device.param and node.param can now be used to configure params when devices
and nodes are created.
- Memory will now try to use MFD_NOEXEC_SEAL.
- The driver id of a node is now placed in the properties.
- A potential race was fixed when adding and removing ports to the scheduling
lists.
## Modules
- Priorities for the FFADO threads can be configured now.
- The loopback module now has support for up and downmixing.
- Extra properties can now be configured per native-connection socket.
- The pulse-tunnel can now automatically reconnect when the connection is
broken.
- The RTP module now supports the PTP management protocol.
- The RTP sender can now use a timer to send out multiple packets per
quantum.
- A new module was added for loading Parametric EQ.
- The simple-protocol module now has per stream configurable properties
and can also be used to interface with a snapcast server.
- Support for local services was added to raop, rtp and pulse avahi
discoverers. Support for IPv6 on local services was added to RAOP.
## SPA
- Support for reporting JSON parsing errors has been added.
- Some extra checks are added when iterating POD structures.
- Port and profiles can now be hidden from ALSA nodes with
api.acp.hidden-ports and api.acp.hidden-profiles properties.
- The UCM conflicting devices patches were merged.
- Profiles and Routes can now also be set by name.
- Hires timestamps are now used when possible in IRQ based scheduling to
get more accurate wakeup times.
- udev can now be an optional dependency.
- audioadapter now has an option to automatically configure its ports.
- Camera rotation was added to the libcamera node.
- invoke on loops can now be done from multiple threads at the same time.
- Make sure we use CLOCK_MONOTONIC everywhere in the io_clock.
- Vulkan bit and convert filters were added.
- ALSA will now always read the HW ringbuffer pointer when followers are
not on the same card.
- Support for larger MIDI sysex messages was improved. Configuration of
the client input and output pool was added. (#4005)
## Bluetooth
- Support Google OPUS codec.
- Support the LC3-SWB codec.
- Support the AAC-ELD codec.
- Broadcast source configuration support was added.
## pulseaudio-server
- The GSettings schemas are now optionally installed.
- Extensions were moved to the modules.
- The log level of the pulse server can dynamically be changed with
a core object message.
- snap access control was added to pulse-server.
- The old pacmd describe-module functionality is now implemented with
a core message pipewire-pulse:describe-module.
- An option was added to disable module loading and unloading.
## JACK
- OSC messages can now also be placed in JACK MIDI and the translation
layer will detect and tag the right PipeWire control message types.
- A jack.other-connect-mode was added to limit the connections that an
app can do to ports it doesn't own.
- The way the transport is started and how the nodes are grouped together
in the transport was improved using the new sync groups. (#3850)
- Fix large MIDI messages handling. (#4005)
## ALSA
- Fix format renegotiation. (#3858)
- Handle period events better. (#3676)
- Improve handling of the eventfd wakeups.
## GStreamer
- The GStreamer elements can now negotiate and use DMABUF.
## Tools
- The T flag is used in pw-top when the transport is running.
- A new pw-container tool was added to start a new security context and
run an application in it.
- pw-dot handles properties with quotes better. Nodes are grouped with the
node.link-group.
- pw-link has a --wait option to wait for all links to be created.
# PipeWire 1.0.6 (2024-05-09)
This is a bugfix release that is API and ABI compatible with previous
1.0.x releases.
## Highlights
- A bitfield race was fixed that could cause some crashes or undefined
behaviour when moving nodes between drivers.
- Fix to some invalid memory access in the pw-mon and pw-dump.
- A regression in kodi with IEC958 formats playback was fixed.
- A race in the ALSA plugin was fixed when updating the eventfd.
- Improvements and fixes to module-combine-stream.
- Negotiation was improved in pipewiresrc.
- Some more small fixes and improvements.
## PipeWire

## SPA
- Support both old and new versions of webrtc-audio-processing to make
the transition easier.
- The ALSA driver now does the sync of all followers directly from the
wakeup event. This results in more stable rate matching.
- IRQ based scheduling in ALSA was improved and enabled by default for
Pro-Audio profile. It will also link the pcms together to get lower
latency. This now matches what JACK does and gives equal latency to
PipeWire for Pro-Audio profiles.

- Some improvements to passthrough handling.
## Bluetooth
- Improvements to the codec handling when PipeWire is used as Audio
Gateway.
