JAX is partially reverting a Pallas Triton PTX compilation change while shipping new configuration controls to prevent auto-pvary insertion from breaking downstream code.

The team partially rolled forward bits needed for Pallas Triton to compile to PTX [1], but this required reverting a prior commit — the change doesn't alter existing Pallas Triton behavior, just restores compilation infrastructure. Parallel to that, JAX is shipping a new config option to disable auto-pvary insertion [2], a necessary escape hatch for teams hitting unexpected behavior from automatic parallelization. The move suggests the auto-pvary feature is too aggressive in its current state and catching real production patterns it shouldn't touch. Minor documentation fixes landed in Pallas pipelining [3], cleaning up typos in the guides. These aren't flashy changes, but they're the friction-reduction work that keeps large compute workloads from breaking between releases.
