The 1st U.S. Circuit Court of Appeals now has RSS Feeds for both its opinions and audio recordings of oral arguments. The court posted this notice:

Along with audio recordings of the court’s oral arguments, electronic versions of the court’s opinions are now available via RSS (Real Simple Syndication), a method of delivering web content directly to you without cluttering your inbox with e-mail. Until now, electronic versions of the court’s opinions were available only through e-mail with an opinion attached. We will soon be phasing out this method and strongly encourage current subscribers to convert to RSS, which will allow you to search, sort, and filter information.

Both feeds are available from this page. As the notice says, the court will phase out e-mail notification of new opinions.
