Feb 1, 2026February 2026 monthly summary for lynx-family/lynx. Delivered profiler and logging enhancements, tightened thread-safety, and stabilized dependencies to improve observability, reliability, and build consistency. Key outcomes include: (1) runtime profiling and logging: integrated Lynx JS runtime profiler with Perfetto-based tracing, ensured a single V8 profiler instance when Lynx is linked as a dynamic library, and hardened log initialization with asynchronous retry to mitigate early-failure boot issues; (2) reliability fixes: implemented thread-safe backtrace delegate by making the global delegate static and guarded with a mutex, preventing race conditions when SetBacktraceDelegate is invoked from multiple threads; (3) dependency alignment: synchronized debugrouter version across DEPS and DEPS.lynxtron to ensure consistent builds and easier cross-repo integration. These changes collectively improve performance diagnosis, reliability, and developer velocity across platforms.

Nov 1, 2025Month: 2025-11. Summary: In November 2025, the Lynx repository delivered infra and tooling enhancements that improved build reliability, dependency management, and platform compatibility, while expanding GN path handling and path conversion consistency. Major outcomes: 1) GN path tooling extended: gn_relative_path_converter.py now handles any // path declaration, and remaining GN paths were converted to relative paths to standardize path references. 2) Dependency management and builds: habitat-based management for modp_b64; buildroot and core libraries updated (BoringSSL, ICU, jsoncpp, abseil-cpp), plus partial build fixes and code style improvements to stabilize builds across toolchains. 3) Platform support and API compatibility: adaptation to V8 14 APIs, Skia-related GN config search path adjustments, and Harmony dev tooling to publish lynx_base dev versions. 4) Quality and maintenance: automated header additions for missing standard-library headers, NAPI header fixes, and code style refinements to improve forward compatibility and readability. These changes reduce build errors, improve porting to new environments, and accelerate AutoSubmit/CI flows. 5) Business value: faster, more reliable builds; easier dependency upgrades; broader GN path support; improved platform compatibility and developer productivity.
