Ask.com announced that Bloglines will be shut down on Novenber 1st.
The Bloglines code is now removed from Liferea trunk (that will become Liferea 1.8), and Bloglines subscriptions are automatically removed.
At least as long as Bloglines is available it will stay supported in the stable Liferea 1.6.
For users of Blogline with Liferea the best choice for similar functionality is to switch to Google Reader and use Liferea's Google Reader support.
Bloglines support is now also removed in the 1.6 branch, the change will be in 1.6.6.
