I don't think the new features page on Autodesk.com main page doesn't really give you the whole story. See below, my take on this year's offering. Note, this is not an exhaustive list.
The new features in Autodesk's user guide does a decent job.
In no particular order:
I will have to made other version for v2014 because I use COM for paletteset control.
I need the MinimumRadiusTableName property for alignments and it doesn´t exist yet.
