2025-10 Monthly Summary for github/codeql — Focused on QL language documentation improvements (Annotations, Signatures, Extensions, Predicate Rules). Consolidated and expanded docs to align with the spec, clarifying usage of the 'additional' annotation, references to signatures, and applicability to type unions. Clarified 'extensible' vs 'external' semantics and enforced that member predicates cannot be external. Refined wording per PR feedback to improve accuracy and consistency across the language reference. No code defects fixed; the impact is improved developer understanding, onboarding, and reduced ambiguity in the language reference.

September 2025 – Delivered Documentation Improvements for QL Annotations in github/codeql. Key updates include alphabetically sorting QL annotations in docs, clarifying applicability to entities vs names, and adding 'additional' and 'extensible' annotations to relevant lists to reflect current capabilities. This work enhances discoverability and accuracy, supporting developers and predicates/classes usage.
