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.
