This is a JAX 0.4.36 compatibility release.
With this release, JAX changed how custom primitive rules are called (they are always called, instead of only when the data requires them to be). That requires some updates in Equinox to avoid crashes in the downstream ecosystem. (patrick-kidger/diffrax#532, jax-ml/jax#25289 + links therein.)
Full Changelog: v0.11.9...v0.11.10
