PipeWire 1.0 retains API/ABI compatibility with the long-lived PipeWire 0.3.xx series. PipeWire 1.0 delivers improved time reporting for less jitter in ALSA when using IRQ mode, various module fixes, Bluetooth LC3 codec and compatibility improvements, improved transport and time handling for JACK, optimized buffer re-use with JACK, and a variety of other improvements.
There isn't anything fundamentally different about PipeWire 1.0 but was part of their plan for releasing 1.0 later in the year and finally moving past all the 0.3.xx releases. PipeWire has proven itself stable and plenty reliable for Linux desktop uses.
