• #701: Add a "skip_actions" option to skip running particular actions, handy for append-only or
  checkless configurations. See the documentation for more information:

• #701: Deprecate the "disabled" value for the "checks" option in favor of the new "skip_actions"
  option.

  side effect of this change, constants no longer apply to option names and only substitute into
  configuration values.
• #779: Add a "--match-archives" flag to the "check" action for selecting the archives to check,
  overriding the existing "archive_name_format" and "match_archives" options in configuration.
• #779: Only parse "--override" values as complex data types when they're for options of those
  types.
• #782: Fix environment variable interpolation within configured repository paths.
• #782: Add configuration constant overriding via the existing "--override" flag.
• #783: Upgrade ruamel.yaml dependency to support version 0.18.x.
• #784: Drop support for Python 3.7, which has been end-of-lifed.
