• BREAKING: Harmonize expect_column_values_to_be_of_type and expect_column_values_to_be_in_type_list semantics in
  Pandas with other backends, including support for None type and type_list parameters to support profiling.
  These type expectations now rely exclusively on native python or numpy type names.
• Add configurable support for Custom DataAsset modules to DataContext
• Improve support for setting and inheriting custom data_asset_type names
• Add tooltips with expectations backing data elements to rendered documentation
• Allow better selective disabling of tests (thanks @RoyalITS)
• Fix documentation build errors causing missing code blocks on readthedocs
• Update the parameter naming system in DataContext to reflect data_asset_name and expectation_suite_name
• Change scary warning about discarding expectations to be clearer, less scary, and only in log
• Improve profiler support for boolean types, value_counts, and type detection
• Allow user to specify data_assets to profile via CLI
• Support CLI rendering of expectation_suite and EVR-based documentation
