- **added** — Added jax.scipy.linalg.invhilbert for the closed-form inverse of the Hilbert matrix
- **added** — Added jax.scipy.linalg.invpascal for the inverse of the Pascal matrix
- **added** — Added jax.scipy.linalg.fiedler_companion for constructing the pentadiagonal Fiedler companion matrix of a polynomial
- **added** — Added jax.ShapeDtypeStruct.like as a shortcut for constructing a jax.ShapeDtypeStruct from an object with shape and dtype attributes
- **changed** — Improved JAX tracing performance

* New features
  * Added `jax.scipy.linalg.invhilbert` for the closed-form inverse
    of the Hilbert matrix ({jax-issue}`#10144`).
  * Added `jax.scipy.linalg.invpascal` for the inverse of the Pascal
    matrix (`#10144`).
  * Added `jax.scipy.linalg.fiedler_companion` for constructing the
    pentadiagonal Fiedler companion matrix of a polynomial
    (`#10144`).
  * Added `jax.ShapeDtypeStruct.like` -- a shortcut for constructing a
    `jax.ShapeDtypeStruct` from an object with `shape` and `dtype`
    attributes.
* We have made a number of improvements to JAX tracing performance.
