Has been fixed already https://gitweb.gentoo.org/data/gentoo-news.git/commit/?id=c19c5f5dea8c56f1d2045c630821e9aa34589bc3 Leaving this bug open to avoid duplicates
Hit this with the stable version of portage: wanderweg ~ # emerge -DupN world These are the packages that would be merged, in order: Calculating dependencies... done! !!! Invalid news item: /usr/portage/metadata/news/2016-04-24-default-video-cards/2016-04-24-default-video-cards.en.txt !!! line 6: News-Item-Format: 2.0 wanderweg ~ # emerge --version Portage 2.2.26 (python 3.4.3-final-0, default/linux/amd64/13.0/systemd, gcc-4.9.3, glibc-2.22-r4, 4.4.5-gentoo x86_64)
After thinking a bit more, this is probably a bug in portage which should ignore (or warn the user about) unsupported News-Item-Format instead of complaining that it is invalid.
