I installed evolution-rss-0.1.4-7.fc12.x86_64 from updates-testing on 12/1 and I've seen no new entries in any of my feeds since then.
I backed off to evolution-rss-0.1.4-5.fc12.x86_64 and all my feeds refreshed.
The difference in changelogs is:
$ rpm -q --changelog evolution-rss | more * Thu Nov 05 2009 Lucian Langa cooly@gnome.eu.org - 0.1.4-7 - add new upstream fix for feeds fetching for evolution > 2.28.1
* Mon Oct 26 2009 Lucian Langa cooly@gnome.eu.org - 0.1.4-6 - add upstream patch to fix loading of feeds for evo >= 2.28.1
Currently, I have evolution-2.28.0-2.fc12.x86_64. So I guess the real question is, why is evolution-rss for evolution-2.28.1 in updates-testing but evolution-2.28.1 is nowhere to be found yet?
