How can CodeQL queries stay up-to-date with new languages and patterns?

• A. Wait for users to report issues.
• B. Regularly update the CodeQL language packs and queries; follow release notes; maintain custom queries.
• C. Never update unless you see a failure.
• D. Copy queries from unrelated projects.

Answer: (B)

Regularly updating the CodeQL language packs and queries, while following release notes and maintaining your own custom queries, is the best way to stay aligned with new languages and patterns. Language packs introduce support for new languages and updated security patterns, and release notes alert you to changes, fixes, and newly recommended queries. Keeping your custom queries maintained ensures they stay relevant as language syntax evolves and as new vulnerability patterns emerge. This proactive approach prevents gaps in coverage and helps you leverage the latest improvements in CodeQL.

Waiting for user reports is reactive and slow, not reliable for timely coverage. Never updating unless you see a failure means you’ll miss important improvements and new language support. Copying queries from unrelated projects can bring in irrelevant or unsafe patterns and create maintenance headaches.
