January 2026: Maintained Homebrew-core spdlog-related dependencies by applying targeted revision bumps across six formulas to ensure users install the latest patched versions. This cross-repo maintenance aligns dependencies with spdlog updates (TileDB, WasmEdge, Gnuradio, Cherrytree, Cabin, ArrayFire) and reduces upgrade friction. Six commits were executed, each performing a revision bump with messages such as 'tiledb: revision bump for spdlog' and 'arrayfire: revision bump for spdlog'. Impact: improved security and stability for end users, smoother upgrades, and consistent patch coverage across related projects. Technologies/skills demonstrated: Git-based release hygiene, Homebrew formula maintenance, dependency management, cross-repo coordination, and clear commit messaging.
