 ## PyMC3 vNext (TBD)
 ### Breaking Changes
 - ⚠ Theano-PyMC has been replaced with Aesara, so all external references to `theano`, `tt`, and `pymc3.theanof` need to be replaced with `aesara`, `aet`, and `pymc3.aesaraf` (see [4471](https://github.com/pymc-devs/pymc3/pull/4471)).
+- ⚠ The `pymc3.memoize` module was removed and replaced with `cachetools`.  The `hashable` function and `WithMemoization` class were moved to `pymc3.util`.
 
 ### New Features
 + `pm.math.cartesian` can now handle inputs that are themselves >1D (see [#4482](https://github.com/pymc-devs/pymc3/pull/4482)).
