JAX handles non-unimplemented layout errors, bumps XLA

JAX now gracefully handles errors other than "unimplemented" when reading layouts, closing a crash path for arrays used after deletion or donation.

JAX changed how it responds when reading layouts fails. Previously, an error other than "unimplemented" during layout reads could surface as a crash; the new behavior handles those errors gracefully and avoids crashes in tests that try to use arrays after their deletion or donation, where a runtime error was being raised [1]. A dedicated test was added to exercise this behavior [1]. The same change landed through the JAX PR pipeline [2].

The other JAX change this cycle is a dependency move: the XLA dependency was updated to a new revision [3]. That means builds pulling JAX now track the newer XLA commit, so anyone pinning or vendoring XLA should align with the revision JAX expects [3].

Neither change is disruptive on its own. The layout error handling is defensive and comes with a test; the XLA bump is a routine revision update that will matter most to consumers building against a fixed XLA SHA [3].
