JAX landed a quiet but meaningful reliability fix this period: program order now sticks even when exclude_argnames is passed as None, plus an XLA dependency roll.

JAX landed a quiet but meaningful reliability fix [1] that makes tracing respect program order even when exclude_argnames is None. The internal commit [2] carries the same change plus a PiperOrigin-RevId, so the two share the same intent. Alongside it, the team reverted a prior commit twice [3][4], signaling instability in the change being rolled back. The XLA dependency moved to a new revision [5], pinning the tree to upstream commit 69325769ed5c4191b16e7f5fd37d5d5ea114a18d. This is routine maintenance: nothing here breaks existing code, but the ordering change could affect tracing semantics in edge cases where exclude_argnames is None. Watch the revert activity if you depend on the feature being recalled.
