 Package: parsnip
-Version: 0.0.3.9002
+Version: 0.0.4
 Title: A Common API to Modeling and Analysis Functions
 Description: A common interface is provided to allow users to specify a model without having to remember the different argument names across different functions or computational engines (e.g. 'R', 'Spark', 'Stan', etc).

 ## New Features
 
-* The time elapsed during model fitting is stored in the `$elapsed` slot of the
-parsnip model object, and is printed when the model object is printed.
+* The time elapsed during model fitting is stored in the `$elapsed` slot of the parsnip model object, and is printed when the model object is printed.
 
 * Some default parameter ranges were updated for SVM, KNN, and MARS models. 
 
+* The model `udpate()` methods gained a `parameters` argument for cases when the parameters are contained in a tibble or list. 
+
+* `fit_control()` is soft-deprecated in favor of `control_parsnip()`. 
+
 ## Fixes
-* [A bug](https://github.com/tidymodels/parsnip/issues/222) was fixed standardizing
-the output column types of `multi_predict` and `predict` for `multinom_reg`.

 * [A bug](https://github.com/tidymodels/parsnip/issues/208) was fixed related to using data descriptors and `fit_xy()`. 
 
 * A bug was fixed related to the column names generated by `multi_predict()`. The top-level tibble will always have a column named `.pred` and this list column contains tibbles across sub-models. The column names for these sub-model tibbles will have names consistent with `predict()` (which was previously incorrect). See [43c15db](https://github.com/tidymodels/parsnip/commit/43c15db377ea9ef27483ff209f6bd0e98cb830d2).
