# 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
- Fix some more fallout of the async nodes rewrite. Fixes some
crackling, xruns and possibly also some crashes in some cases.
- Fix freewheeling timeouts in case of xruns. This fixes ardour export.
- Fix event mixdown in JACK. Fixes qsynth and possibly other apps.
- Some more small fixes and improvements.
## PipeWire
- Add a new SPA_IO_CLOCK_FLAG_XRUN_RECOVER flag when the process function
is called because of xrun recovery.
- Properly stop nodes in all cases, this avoids spurious xruns and
scheduling errors. (#4122)
- Make sure async nodes receive an async link in all cases. Do the
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.
## Modules

recover from the error. (#4121)
- Fix a (harmless) warning in module-rtp because of comparing samples and
time. (#4095)
## SPA
- Let the freewheel driver detect xrun recovery and handle the timeouts
correctly. This fixes an issue with ardour export.

with no way to detect this.

is woken up to process the queue.
## JACK
- Don't check timestamps when mixing down events. The timestamps are only
checked when writing new events with the public API. This fixes an
issue where qsynth would not receive midi events anymore.
- Fix the jack_get_time() function, it was returning nano instead of micro
seconds.
