base changelog incorrectly attributes Ix instances for Foreign.C.Types

On the master branch, the base changelog currently lists this under the base-4.17.0.0 changes:

The following Foreign C types now have an instance of Ix: CChar, CSChar, CUChar, CShort, CUShort, CInt, CUInt, CLong, CULong, CPtrdiff, CSize, CWchar, CSigAtomic, CLLong, CULLong, CBool, CIntPtr, CUIntPtr, CIntMax, CUIntMax.

However, these were actually added in base-4.16.1.0, not 4.17.0.0. See dd4f50d8, the commit which adds them to the ghc-9.2 branch. While the changelog was correctly attributed on the ghc-9.2 branch, that has not been forward-ported to the master branch.
