Fortunately, the list is pretty short:
- The ColdFusion API Manager (for more, see this summary and still more details)
- The Security Analyzer (called from within ColdFusion Builder, but works only against CF Enterprise...and not even CF Developer edition). More in the docs
Before any chime in to complain about the fact that these features are Enterprise-only (and that the Security Analyzer is not even supported against the free Developer edition), I do agree with you. These were both quite surprising to most paying close attention. (There's even a more subtle limitation regarding the Security Analyzer: it only works against an Enterprise CF deployment if that deployment is running with the "Developer profile", not either the "Secure" or "Production" profiles.)
Update: See my comment below about how you can use an Enterprise license key on a dev/test server, to allow you to use the Analyzer on other than your production server. An Adobe representative confirmed my observation today on the Adobe webinar reviewing CF 2016 (recording to be posted there soon, if not by the time you read this.)
FWIW, if you would like to find a more substantial comparison of the differences between CF Enterprise and Standard (including all the differences that are NOT new to CF2016), see this Buying Guide table from Adobe.
