GitHub Advanced Security customers can now edit their custom patterns defined at the repository, organization, and enterprise levels. After a user edits and saves a pattern, secret scanning searches for matches both in a repository's entire git history and in any new commits. Editing a pattern will close alerts previously associated with the pattern if they no longer match the updated version.
The new editing feature comes along with other UI and UX updates, with additional improvements like dry-runs in the works.
Now that users can edit their patterns, we're also taking custom patterns out of beta on cloud. Over 50 enterprises have adopted the feature and written over 100 unique patterns since the initial release in June.
User-defined patterns will be generally available on server next quarter in GitHub Enterprise Server 3.3.
