May 2025 – Semgrep/semgrep: Julia Parser Upgrade delivered to improve analysis of Julia code. Upgraded the Julia parser to a newer tree-sitter-julia version and refactored parsing of function definitions, assignments, and other syntax for alignment with the updated parser structure. Result: higher accuracy and robustness in Julia analysis and preparation for broader Julia support. This work underpins reliable code checks and detections in Julia projects.

In 2025-01, delivered a targeted documentation update in semgrep-docs to improve contributor experience for language support contributions. Replaced placeholder 'X' with '$PL' in code samples across language contribution docs to reflect real environment-variable usage, enhancing clarity and reducing onboarding friction. Commit 195b0711ffba384dfacc150e053c05aa6a1cb810 provides traceability and reproducibility (#1912). Overall, this improves maintainability and lowers support overhead by ensuring contributors follow a consistent, real-world example pattern.
