 + Automatic imputations now also work with `ndarray` data, not just `pd.Series` or `pd.DataFrame` (see[#4439](https://github.com/pymc-devs/pymc3/pull/4439)).
 
 ### Maintenance
+- We upgraded to `Theano-PyMC v1.1.2` which [includes bugfixes](https://github.com/pymc-devs/aesara/compare/rel-1.1.0...rel-1.1.2) for warning floods and compiledir locking (see [#4444](https://github.com/pymc-devs/pymc3/pull/4444))
 - `math.log1mexp_numpy` no longer raises RuntimeWarning when given very small inputs. These were commonly observed during NUTS sampling (see [#4428](https://github.com/pymc-devs/pymc3/pull/4428)).
