CodeQL 2.27.3 adds Python 3.15 support and JSON data extensions
GitHub released CodeQL 2.27.3, the static analysis engine behind GitHub code scanning. The release adds support for new Python 3.15 language features and JSON data extensions.

Why it matters
Teams scanning Python 3.15 codebases with CodeQL can now analyze newer language syntax, and JSON data extensions allow CodeQL to model JSON-based data flows in code scanning.
Who should care
Developers and security teams using GitHub code scanning on Python projects, especially those adopting Python 3.15.
What you can do
Update to CodeQL 2.27.3 in your CI or code scanning setup and rerun scans on Python 3.15 projects to check for coverage gaps.
