GitHub Advanced Security customers can now view and resolve private repository secret scanning results via the GitHub REST API. In addition, a webhook is available whenever a new committed secret is detected. The new API endpoints and webhooks will be in beta until early next year.
Dependabot already updates your public dependencies, such as open source dependencies from a public GitHub repository, npm, Maven Central, or similar. Now, you can also update dependencies from private GitHub repositories. This feature is available for most package managers supported by Dependabot version updates, except bundler, hex, and pip.
