- Updated from version 0.7.0 to 0.8.0
- Update of rootfile
- Changelog
    0.8.0 (2022-05-22)
	    Accept os.PathLike[str] in addition to str for paths in public API
             (PR #392, Fixes #372)
	    Add schema validation for build-system table to check conformity with PEP 517
             and PEP 518 (PR #365, Fixes #364)
	    Better support for Python 3.11 (sysconfig schemes PR #434, PR #463,
             tomllib PR #443, warnings PR #420)
	    Improved error printouts (PR #442)
	    Avoid importing packaging unless needed (PR #395, Fixes #393)
	Breaking Changes
	    Failure to create a virtual environment in the build.env module now raises
             build.FailedProcessError (PR #442)
- As far as I can tell IPFire does not use the build.env module and the built iso
   installed successfully
