This week, they deprecated the Google Feed API. Unfortunately, many Blogger gadgets require that feature to display feed content, on our blogs.
This week, numerous reports about broken feeds, in various gadgets, are being seen, in Blogger Help Forum: Get Help with an Issue. The broken feeds are a direct result of the deprecated API.
Blogger Engineering is now aware of the problem - and is working hard to correct the cause of the problem.
This problem won't be fixed, in a one day effort.
The gadget update, which was started today after the API deprecation was identified as the cause of the reported problems, won't be finished in a one day project.
Engineers must first develop a replacement Blogger Feed API.
The Blogger Engineers have to first develop a replacement for the deprecated API - then they have to update each broken gadget.
Then, each broken gadget must be fixed, to use their API.
They will shortly be updating the gadgets that they know are broken - but it's always possible they might overlook one. They might even overlook the gadget that you depend upon, for your blog to provide content, for your readers. These are the currently identified problems.
