0.5.5 Disallow multiple `_` in a row in digits, e.g. `1__000`. #1138. Fixed toposort example. Struct/union members now correctly rejects members without storage size #1147. `math::pow` will now correctly promote integer arguments. `math::pow` will now correctly promote integer arguments. Added `new_aligned` and `alloc_aligned` functions to prevent accidental under-alignment when allocating simd. Pointer difference would fail where alignment != size (structs etc) #1150. Add test that overalignment actually works for lists. Fixed array calculation for npot2 vectors. Use native aligned alloc on Windows and POSIX. Deprecates "offset". Simplification of the Allocator interface.
