In Oct 2024, delivered improvements in the github/vscode-codeql repository focused on making SARIF comparisons more reliable and maintaining a clean dependency footprint. The main feature refined SARIF diffing to consider only the source and sink of code flows, reducing noise from intermediate paths, supported by added tests and updated documentation. Additionally, performed dependency hygiene by removing an unused @types/nanoid package and upgrading @faker-js/faker to version 9. These changes enhance developer productivity, reduce false positives in SARIF-based reviews, and lower maintenance risk by keeping dependencies current.
