 ## Breaking Changes
 
- * The method that `parsnip` stores the model information has changed. Any custom models from previous versions will need to use the new method for registering models. The methods are detailed in `?get_model_env()` and the [package vignette for adding models](https://tidymodels.github.io/parsnip/articles/articles/Scratch.html).
