There are a number of goodies in this release for FrameMaker. The GUI has been improved, multi-channel publishing (Responsive HTML5, ePub, Kindle, WebHelp, and Microsoft
HTML Help), regex search/replace, QR codes, improved PDF commenting/review (you keep on editing the FM docs!), simpler Conditional pod & better conditional expression handling, improvements in the XML/DITA modes, a new simplified XML Author mode (and also as a cheaper stand-alone product), direct links to Dropbox and other cloud-based storage services and more. It's more stable, faster and yes, bugs have been fixed (though there is some debate as to what is a bug vs. feature vs. "as designed" vs. can't duplicate vs. WTF?)
.This one's worth checking out.
