Dear Colleagues, Tomorrow (Wednesday 4th December), as part of the Whois 1.96 release, we also plan to remove the "mnt-lower" attribute from all "aut-num" objects.
Following the Whois release, this attribute will be filtered out from aut-num updates with a warning (i.e. updates won't fail). We will notify the DB-WG again once this is complete.
