Code scanning default setup now automatically attempts to analyze all CodeQL supported languages in a repository. This means default setup supports all CodeQL languages at the organization level, including enabling code scanning from an organization's Security Overview coverage page or settings page.
Previously, users would have to manually include the languages C, C++, C#, Java, or Kotlin in a default setup analysis, and enabling these languages was not supported at the organization level. Now, code scanning default setup automatically attempts to analyze all languages supported by CodeQL in a repository. If any analyses fail, the failed language will be automatically deselected from the code scanning configuration. Any alerts from the successfully analyzed languages will be shown on GitHub. This means code scanning will automatically set up the best possible configuration to get started easily with CodeQL and show the most relevant alerts to developers.
A warning banner is shown in the repository settings page if any languages fail and are deseslected. The "edit configuration" page shows all languages in the configuration, and allows users to change the language selection if required. For more information about the languages and versions supported by CodeQL and code scanning, see Supported languages and frameworks. To learn more about code scanning, see About code scanning.
