Since the last app-office/libreoffice-bin upgrade was long-delayed and overall slightly painful, we've modernized behind the scenes. Patrick Lauer a.k.a. bonsaikitten, who is amongst other things already running the commit notification bot irker on #gentoo-commits and the amazing AutoRepoman verifying quality and consistency of the portage tree, has provided me with generous access to two dedicated build chroots for amd64 and x86 libreoffice on a rather fast server. Together we're trying to automatize the upgrade process as much as possible. The app-office/libreoffice-bin-18.104.22.168 packages that I'm uploading right now and that will appear on the mirror servers and in the portage tree within the next 24h are the first result of the new setup. Test and enjoy!
Oh yeah, and since many people have asked me already, the awesome new splash screen was contributed by Denis M. a.k.a. Phr33d0m, see bug 456666. Thanks a lot too!
