The screenshots are more recent (including some new ones).
The welcome email images have not been updated as some things have to be
answered before that can be done.
The current files were renamed to be shorter as well.
This addresses most (if not all) of the recent changes to chkentry(1)
though a more thorough check will be made later after the mkiocccentry
code freeze.
It is highly recommended that you run the tool from either the repo
directory itself (making sure you have the most up to date version of
course) or make sure you have installed it (also making sure you have
the most recent version). Not doing this will cause issues with checks
and in the case of out of date versions the submission would be rejected
due to violating rule 17. One can specify the options to mkiocccentry
for the tools required but if you forget or don't have the most up to
date version you will very likely run into problems.
The FAQ and guidelines need to be improved in this regard but the quick
start guide is now consistent with the syntax found in mkiocccentry
(which is noted in the FAQ).
