I am starting to compare the nightly release against my local build and found the following files are in the nightly 7z, but should not be IMHO:
share\CodeBlocks\images\fortranproject\Makefile.am
share\CodeBlocks\images\fortranproject\56x56\Makefile.am
share\CodeBlocks\images\fortranproject\64x64\Makefile.am
share\CodeBlocks\images\fortranproject\48x48\Makefile.am
share\CodeBlocks\images\fortranproject\40x40\Makefile.am
share\CodeBlocks\images\fortranproject\32x32\Makefile.am
share\CodeBlocks\images\fortranproject\28x28\Makefile.am
share\CodeBlocks\images\fortranproject\24x24\Makefile.am
share\CodeBlocks\images\fortranproject\16x16\Makefile.am
share\CodeBlocks\images\fortranproject\20x20\Makefile.am
share\CodeBlocks\images\fortranproject\gnuplot_gdb_surface.dem
share\CodeBlocks\images\fortranproject\gnuplot_gdb.dem
share\CodeBlocks\images\fortranproject\fortran_intrinsic_modules.f90
share\CodeBlocks\images\fortranproject\gdb_fortran_extensions_v1.1.py
share\CodeBlocks\images\fortranproject\fortran_procedures.f90
These are in the images share\CodeBlocks\images directory, but are not images.
BTW These were also in the 20.03 release as well.
