+* The CMake projects require 3.21 or later. VS 2019 users will need to install a standalone version of CMake 3.21 or later and add it to their PATH.
+
 * Starting with the July 2022 release, the ``bool forceSRGB`` parameter for DDSTextureLoader ``Ex`` functions is now a ``DDS_LOADER_FLAGS`` typed enum bitmask flag parameter. This may have a _breaking change_ impact to client code. Replace ``true`` with ``DDS_LOADER_FORCE_SRGB`` and ``false`` with ``DDS_LOADER_DEFAULT``.
 
 * There are known codegen issues when mixing the library built with Visual C++ and the sample built with recent builds of clang/LLVM for Windows. Building both the library and the sample using the same complier avoids the issue.
