 ## PyMC 3.11.5 (TBD)
 ### Backports
 + The `pm.logp(rv, x)` syntax is now available and recommended to make your model code `v4`-ready. Note that this backport is just an alias and much less capable than what's available with `pymc >=4` (see [#5083](https://github.com/pymc-devs/pymc/pulls/5083)).
++ The `pm.Distribution(testval=...)` kwarg was deprecated and will be replaced by `pm.Distribution(initval=...)`in `pymc >=4` (see [#5226](https://github.com/pymc-devs/pymc/pulls/5226)).
++ The `pm.sample(start=...)` kwarg was deprecated and will be replaced by `pm.sample(initvals=...)`in `pymc >=4` (see [#5226](https://github.com/pymc-devs/pymc/pulls/5226)).
 
 ## PyMC3 3.11.4 (20 August 2021)
