GitHub Advanced Security customers can now dry run custom secret scanning patterns at the repository level. Dry runs allow admins to review and hone their patterns before publishing them and generating alerts.
Admins can compose a pattern then 'Save and dry run' to retrieve results from their repository. The scans are fast – typically just a few seconds – but GitHub will also notify admins via email when dry run results are ready. Organization and enterprise-level dry runs will follow shortly.

As you may or may not know, gists are actually Git repositories. New gists are now created with a default branch name of either main or the alternative default branch name you've defined in your user settings. This matches how other repositories are created on GitHub.
