… 0.10.2 crash) The last stable tensorflow-probability (0.25.0) references jax.interpreters.xla.pytype_aval_mappings, removed from modern JAX, so it crashes at import under the resolved jax>=0.7 stack — breaking every Matern-kernel pixelization on the JAX backend (release-validation run 29266305445). Swap the pin to tfp-nightly==0.26.0.dev20260713 (verified to compute bessel_kve on jax 0.10.2) and correct the kv_xp docstring/ImportError.

Summary
The JAX Matern-kernel regularization path crashed at import for every user on the release-resolved stack.
autoarray/inversion/regularization/matern_kernel.py(kv_xp) importstensorflow_probability.substrates.jaxforbessel_kve; the last stable tfp (0.25.0) referencesjax.interpreters.xla.pytype_aval_mappings, removed from modern JAX, soimportcrashes underjax 0.10.2. Surfaced by release-validation run29266305445(TestPyPI2026.7.13.1.dev65501).Fix
pyproject.toml(optionalextra):tensorflow-probability==0.25.0→tfp-nightly==0.26.0.dev20260713. No stable tfp is compatible (0.25.0 is the latest); the nightly restores modern-JAX support and installs via an explicit==pin (no--pre). Import name is unchanged, somatern_kernel.pyneeds no code edit.matern_kernel.py: corrected thekv_xpdocstring (it advertised a non-existentjax.scipy.special.kvfast-path) and pointed theImportErrorattfp-nightly. No behaviour change.Why not the alternatives
pytype_aval_mappingsis gone by jax 0.9.2 andautoconf[jax]floorsjax>=0.7.jax.scipy.specialhas nokv/kve, andnuis a continuous free prior, so no closed-form shortcut. Vendoring tfp'sbessel_kveis the durable fix, filed as a follow-up.Verification
