September 2025: Focused on making build outputs deterministic in rules_swift, delivering a change that unconditionally passes -file-prefix-map to the Swift compiler and updating tests accordingly. This reduces nondeterministic paths in build artifacts and stabilizes CI/tests for bazelbuild/rules_swift.

June 2025 monthly summary for grpc/bazel-central-registry focusing on Rules Swift 3.x compatibility upgrade across build dependencies and Bazel rules. Executed extensive dependency upgrades, patches, and alignment to ensure compatibility with Swift toolchain changes, improving build stability and downstream maintainability.

November 2024 monthly summary for bazelbuild/rules_swift focusing on expanding Swift packaging semantics. Delivered semantic package_name support for Swift targets in the mixed_language_library rule, enabling semantic packages and use of the Swift 'package' access modifier with Swift 5.9+. The change is tracked in commit 61e2c46dbfac6b9c11ecfb2c8e92f3e157ea9f27 (PR #1458). No major bugs fixed this month; main emphasis was feature delivery and impact on cross-language packaging workflows.
