Not too much at the moment, but according to this BBC story, Shane Bauer and Josh Fattal, the two remaining American hikers who had been seized and charged with espionage have been released from the Iranian prison in which they had been incarcerated.
The article says that each one was released "on $500,000 bail," and had their sentences commuted. I don't know if this is essentially a "bribe" to the Iranian government or not, but, in the grand scheme of things, I am far happier with the final result that they should be reunited with their families in the not too distant future.
