wxPython 4.2.1 compile issue. Can I use a newer version?

[okoolo]

requirements file has wxPython==4.2.1
Do I really need that specific wxPython version? My distro (catchyOS) has 4.2.4.1 so I need to compile the wheel for 4.2.1 (cant find a precompiled wheel) which turns out to be a major hassle. Namely I get siplib compile errors:
