CodeQL 2.23.9 has been released. This version serves as the static analysis engine powering GitHub code scanning, which is designed to identify and resolve security vulnerabilities within codebases. While this release does not introduce any new user-facing changes to the CodeQL CLI or its queries, its availability is being formally acknowledged.
Deprecation Notice
Support for Kotlin versions 1.6 and 1.7 is being deprecated. These versions will be removed in CodeQL 2.24.1, which is scheduled for release in February 2026. To extract Kotlin databases after this update, users will need to utilize Kotlin 1.8 or a newer version.
New CodeQL versions are automatically deployed to users of GitHub code scanning on github.com. The features introduced in CodeQL 2.23.9 will also be incorporated into a future GitHub Enterprise Server (GHES) release. For those using an older GHES version, a manual upgrade of the CodeQL version is an option.
