# PipeWire 1.2.2 (2024-07-31)
This is a bugfix release that is API and ABI compatible with the
previous 1.2.x and 1.0.x releases.
## Highlights

is called because of xrun recovery.
- Properly stop nodes in all cases, this avoids spurious xruns and
scheduling errors. (#4122)

processing of source output ports slightly differently to make sure we
don't cause latency for sources. (#4138) (#4133)
- Fix some races when negotiating and starting nodes. (#4094)
- Actually include the config.h header to use malloc_trim() to reduce
memory usage in pulse-server.

# PipeWire 1.2.0 (2024-06-27)
This is the 1.2 release that is API and ABI compatible with previous
1.1.x and 1.0.x releases.
This release contains some of the bigger changes that happened since
the 1.0 release last year, including:
* 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 transport 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 negotiating 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.
* Explicit sync metadata and support was added.
* 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.
* Add snapcast-discover module to stream to snapcast servers.
* Rework how peers are linked and the counters are updated. Resume the
peers when a node is unlinked and not yet processed. This should cause
less occasional dropouts in the graph when reconnecting things.
* Many GStreamer element updates.
* Many more fixes and improvements.
Enjoy the summer vacation!
