C++ conformance improvements include relaxed designated initialization rules, constexpr new[] in modules, fixed type deduction through nested lambdas, and several internal compiler error fixes. ARM64 gets vectorization for floor/ceil/trunc/round, improved NEON code generation, and load-pair/store-pair fusion. x64 gains APX instruction set extensions, AVX-512 fixes, and popcount improvements. The optimizer sees new passes including expression reassociation, earlier loop-invariant code motion, and type-based devirtualization with PGO. The linker fixes incremental linking crashes and reduces PDB file size growth. Over 50 community-reported tickets are resolved in this update. ## Full article daily.dev links to this article rather than hosting it.
