2.0.0 General Release

What's Changed

This is mostly a refactor of code with one user-facing difference: the addition of the delete_if_exists input field. There isn't any expected behavioral change, but this is being published as a major version release to make it clear there may be behavior differences if the Action is being used in a non-standard way.

• Version 2.0.0-beta Introduction by @LanceMcCarthy in #277
