 ## [Unreleased]
 
+### Changed
+
+- Change CMake from using `PARENT_SCOPE` to `CACHE INTERNAL` as it seems in some setups using
+  pFUnit via `FetchContent` the former does not work as expected.
+- Update some `cmake_minimum_required` to 3.12 to avoid some warnings
+- Update some `COMMENT` lines in functions with double-quotes to avoid warnings
+
 ## [4.11.1] - 2025-02-04
 
 ### Fixed
