That doesn't really make sense to me. There is no real urgency in getting the new format right now, and omitting the most important issue is not really the solution here. > The problem with any visibility filtering is that visibility depends > on user configuration [1], and I don't know what changes in the > package manager would be necessary to make this work correctly and > efficiently.

Autounmasking is not something you do often on stable systems, and we have better QA to avoid issues that could require it. What's most important right now is to have Portage process news items after 'emerge --sync' (or any other emerge operation), check visibility of packages (with current configuration) and enable news items that apply. We could also process changed news files on emerge start, and warn verbosely that new news items start applying. > [1] https://bugs.gentoo.org/show_bug.cgi?id=290038#c9 -- Best regards, Michał Górny <http://dev.gentoo.org/~mgorny/>
