 - Added the `--pkg` option allowing the download of an `InstallAssistant` package, utilising an update alresdy made to the `installinstallmacos.py` fork. For Big Sur or greater only. This will probably need some more error checking.
 - Added the `--keep-pkg` option which prevents the deletion of the package if the `--move` option is used to extract the package to `/Applications`. By default, the package will be deleted on successful extraction.

 - Added `Makefile`. This allows you to build a self-contained package containing `erase-install.sh` and `installinstallmacos.py` so that curl is not used during the run of `erase-install.sh` to update `installinstallmacos.py`. This requires `munkipkg` and expects to find the `grahampugh` fork of `installinstallmacos.py` in `../macadmins-scripts`. Make sure you don't bundle in Greg Neagle's version of `installinstallmacos.py` inadvertently (or this script will fail). A package will be provided on GitHub for this and subsequent versions. Note that `erase-install.sh` is installed into `/Library/Management/erase-install`. I deliberately have not put `erase-install.sh` into the PATH.
 - Added the `--user` and `--stdinpass` arguments when running on a Silicon Mac. Silicon Macs require an admin user and password to run `startosinstall`.
 - Now treats `10.x` or `11`+ as major versions for OS comparisons.
+- Fix in `installinstallmacos.py` for `os` comparisons failing where no Version is provided from the catalog.
