After the upgrade to 6.0.4, I went to my ownCloud to check out the latest news from my RSS feeder, and it was gone. No more News option in the left panel.
I clicked the + button at the bottom of the option panel, saw News was still available, and I enabled it. Went back to the main screen, my News option was available, and then found all my feeds showing. Whew. No longer cut off from the world.
So handy hint to the ownCloud upgraders - don't turn off the News Enabled flag, leave it in the current setting. Now I'll go and find how to report this to them.
