Jan 1, 2026For Jan 2026, fmtlib/fmt delivered tangible business value through memory and includes cleanup, performance improvements via early exit, and extensive portability/maintainability upgrades. Key features delivered include memory and includes cleanup (standardize memcpy usage, fix memset usage, move <new> include to the implementation), early exit optimization to avoid unnecessary work and improve control flow, and code quality improvements (minor cleanup, header consolidation moving copy and _BitInt to format.h). Modernization efforts include relaxing constexpr for broader compiler compatibility, adding alias for unsigned long long, deprecation opt-in, and removal of deprecated const_check. Major fixes include the early exit path and removal of old assert_fail, plus MSVC workaround merges to improve portability. These changes collectively reduce runtime overhead, simplify error handling, broaden compiler support, and improve maintainability for downstream projects.
