     - `src/gtk-fortran_funptr.csv`: list of all the `funptr` types used in the prototypes of the C functions. Generated by the `cfwrapper/cfwrapper.py` script, which will also print the number of `funptr` in its statistics.
 - `src/build.sh` (backported from gtk4 branch) is now an interactive script proposing to build, test and install gtk-fortran. It uses the default Fortran compiler, then build and test with Intel ifx.
 - `cmake/cmake_uninstall.cmake.in`: improved the code layout (backported from gtk4 branch).
+- `CMakeLists.txt`: backported GTK_SEMANTIC_VERSION and GLIB_SEMANTIC_VERSION from gtk4 branch.
 
 ### Fixed
 - `src/gtk-fortran.pc.in`: the line `Libs:` was modified to fix a problem with the macOS linker (which is not GNU ld and does not accept the `-R` option).
