December 2025: Security-focused code quality improvement in ankidroid/Anki-Android. Implemented a new lint rule to enforce the use of openInputStreamSafe() over openInputStream(), mitigating path traversal vulnerabilities and tightening IO security. Change tracked under Issue 19663 with commit 12a51709a7de10541625a76389e7b7cd6f8c3666; co-authored by David Allison. This work enhances static analysis coverage, reduces risk in file IO operations, and improves maintainability.

November 2025 (2025-11) — dart-lang/sdk delivered focused improvements to the linting subsystem by enhancing the parameter reassignment checks in the linter, expanding coverage to anonymous function expressions and constructor declarations, and adding tests for parameter assignments in if-else branches. This work, executed via two dedicated commits, strengthened code quality checks, reduced false negatives, and improved developer feedback on potential parameter reassignment issues. The changes address issues 61175 and 58659 and were reviewed by core maintainers, with auto-submit coordination.
