Spoken to 2 people at Microsoft and neither one of them can confirm or provide a feature break down list.
Really? Because I found it in about 10 seconds with Google.
Features Supported by the Editions of SQL Server 2014
Note
For features supported by Evaluation and Developer editions see the SQL Server Enterprise feature set.
Additionally if you have an MSDN subscription (personally or through work) you can also access the SQL Server software. If that does not work and the developer price is too high you can get SQL Server Enterprise Edition for 180 days on a trial period.
