We have released FEI 2.0.15 yesterday. The improvements in this release are mostly visual. As such, we have put together a short video walkthrough 
(under 2min).
I am particularly fond of the MIME type definitions in the MIME Structure View 
We have covered some of the key types—if there are any additions you would like to see, please let us know!
As usual, you can find the changelog below. The new version is available for download 
here when you are ready. Enjoy!
