collect_extracts() method for workflow sets (#156).collect_metrics() and collect_predictions() are the only functions that received changes (#151, tidymodels/tune#863).eval_time argument to rank_results() breaks passing-by-position
for the select_best argument.collect_notes() method for workflow sets (#135).fit() and predict() (#137).type, to the workflow_set autoplot() method. The
default, "class", retains the existing behavior of mapping model type to
color and preprocessor type to shape, while the new "wflow_id"
type maps the workflow IDs to color (#134).extract_parameter_dials() and extract_parameter_set_dials() extractors
will now return the parameter or parameter set
that will be used by the tuning function utilized in workflow_map().
The extractors previously always returned the parameter or parameter set
associated with the workflow contained in the info column, which can be
overridden by passing a param_info argument to option_add(). The
extractors will now first look to the added options before extracting from
workflows (#106).workflow_set() and set
fn = "tune_cluster" in workflow_map() to use this feature (#125)!fit_best() method for workflowsets that takes in a workflow set
evaluated with workflow_map() and returns a workflow fitted with the model
configuration associated with the best performance (#126).pull_*() functions to now warn on every usage
(#123).New extract_parameter_set_dials() and extract_parameter_dials() methods to
extract parameter sets and single parameters from workflow_set objects.
Added support for case weights via a new case_weights argument
to workflow_set() (#82).
update_workflow_model() and update_workflow_recipe() were added. These are analogous to workflows::add_model() or workflows::add_recipe() (#64).
Updated tests related to changes in workflows 0.2.5 (#75).
as_workflow_set() can now take a mixture of workflows or tune_results objects.
option_add() now checks the names of the options to see if they are valid names for the functions that receive them (#66)
Fixed an autoplot() bug where, if one metric is selected but a ranking metric is not specified, the wrong metric is used to order the workflows (#52)
Updated pillar formatting for options objects.
New extract_*() functions have been added that supersede the existing pull_*() functions. This is part of a larger move across the tidymodels packages towards a family of generic extract_*() functions. The pull_*() functions have been soft-deprecated, and will eventually be removed
workflow_map() does not fail if there are missing packages or if the function being mapped fails.
