Zig 0.16
A three-month gap, then the compiler. Zig 0.16 renamed GeneralPurposeAllocator to DebugAllocator. Every test that built a GPA does the rename. The README’s hypothetical example does too. Nothing about layout, CUDA, or ops changes.
It is the cost of staying in a language that still moves. The library remains early. The compiler is not.
