October 2025: Key features delivered and bugs fixed across TT Metal and TT UMD, enhancing code quality, release reliability, and API accessibility. Delivered ClangTidy 24.04 in tt-metal CI to strengthen static analysis, and fixed API headers packaging in tt-umd by including all headers from the api/ directory in CMakeLists.txt. Impact: earlier issue detection, consistent releases, and improved API consumption for downstream users. Technologies: ClangTidy, CI configuration, and CMake-based packaging.

September 2025 monthly summary for tenstorrent/tt-metal: Delivered key build and deployment improvements, fixed critical linting and packaging issues, and strengthened CI reliability. The work reduced maintenance overhead, accelerated deployments, and improved distribution readiness for downstream users. Key features delivered included adopting the system-provided Protobuf to simplify builds and reduce bundled dependencies; introducing a Cloudsmith Debian package publishing workflow to automate Debian releases; upgrading CI stability by adopting actions/download-artifact v5.0; extending Clang-Tidy analysis timeout to 90 minutes to accommodate larger PRs; and preparing TT-Train integration for pre-built TT-NN packages with CMake compatibility and include-path updates. Major bugs fixed encompassed excluding generated .pb.cc files from Clang-Tidy linting (solving misconfiguration that blocked linting on generated files); correcting CI package version formatting for single-config generators; and adding missing API headers along with resolving SDK packaging issues to ensure all necessary files are included. Overall impact and accomplishments: these changes reduce build-maintenance cost, shorten release cycles, and improve product reliability and distro readiness. The improvements also lay the foundation for smoother TT-Train integration and more robust CI workflows across future milestones. Technologies/skills demonstrated: CI/CD automation (GitHub Actions), Protobuf system integration, Clang-Tidy linting and configuration management, CMake build improvements, packaging and distribution (Cloudsmith, Debian), and multi-repo collaboration with versioned commits.
