Once you have a clear idea of the changes needed, post a clear email on changes needed to the devel-announce list. Wait at least a week to allow maintainers to make changes or ask you further questions about the change on the devel list. If the change must be done due to some deadline, please note it in the email. If you intend to have provenpackager(s) or an automated process simply make the changes to all unchanged packages, please note that as well in the email.
