 - `src campaign [validate|apply|preview]` now print an error and usage information if a user accidentally provides an additional argument. [#384](https://github.com/sourcegraph/src-cli/pull/384)
 - Fix a regression that was introduced by [#361](https://github.com/sourcegraph/src-cli/pull/361) and caused the "Resolving repositories" step of `src campaign [apply|preview]` to crash when the search query in the campaign spec yielded file matches and repository matches from the same repository.
