RELEASE-NOTES.md

@@ -39,9 +39,13 @@ All of the above apply to:
 - `pm.sample_prior_predictive`, `pm.sample_posterior_predictive` and `pm.sample_posterior_predictive_w` now return an `InferenceData` object by default, instead of a dictionary (see [#5073](https://github.com/pymc-devs/pymc/pull/5073)).
 - `pm.sample_prior_predictive` no longer returns transformed variable values by default. Pass them by name in `var_names` if you want to obtain these draws (see [4769](https://github.com/pymc-devs/pymc/pull/4769)).
 - `pm.sample(trace=...)` no longer accepts `MultiTrace` or `len(.) > 0` traces ([see 5019#](https://github.com/pymc-devs/pymc/pull/5019)).
+- `logpt`, `logpt_sum`, `logp_elemwiset` and `nojac` variations were removed. Use `Model.logpt(jacobian=True/False, sum=True/False)` instead.
+- `dlogp_nojact` and `d2logp_nojact` were removed. Use `Model.dlogpt` and `d2logpt` with `jacobian=False` instead.
+- `logp`, `dlogp`, and `d2logp` and `nojac` variations were removed. Use `Model.compile_logp`, `compile_dlgop` and `compile_d2logp` with `jacobian` keyword instead.
+- `model.makefn` is now called `Model.compile_fn`, and `model.fn` was removed.
+- Methods starting with `fast_*`, such as `Model.fast_logp`, were removed. Same applies to `PointFunc` classes
 - The GLM submodule was removed, please use [Bambi](https://bambinos.github.io/bambi/) instead.
 - `pm.Bound` interface no longer accepts a callable class as argument, instead it requires an instantiated distribution (created via the `.dist()` API) to be passed as an argument. In addition, Bound no longer returns a class instance but works as a normal PyMC distribution. Finally, it is no longer possible to do predictive random sampling from Bounded variables. Please, consult the new documentation for details on how to use Bounded variables (see [4815](https://github.com/pymc-devs/pymc/pull/4815)).
-- `pm.logpt(transformed=...)` kwarg was removed (816b5f).
 - `Model(model=...)` kwarg was removed
 - `Model(theano_config=...)` kwarg was removed
 - `Model.size` property was removed (use `Model.ndim` instead).
