+  The functions `sizeof()`, `strideof()`, and `alignof()` have been removed.
+  Instead, these memory layout properties for a type `T` are now spelled
+  `MemoryLayout<T>.size`, `MemoryLayout<T>.stride`, and
+  `MemoryLayout<T>.alignment`, respectively.
+
+  The functions `sizeofValue()`, `strideofValue()`, and `alignofValue()` have
+  been renamed `MemoryLayout.size(ofValue:)`, `MemoryLayout.stride(ofValue:)`,
+  and `MemoryLayout.alignment(ofValue:)`.
