Changes to the protection engines (many of which affect Norton as well) are published here:

Additional information on released definitions is available as well.
IPS Definitions
Virus and Behavioural Blocking Definitions (small number of definitions do not apply to Norton and SEP as they are designed for the Symantec Adaptive Protection. These definitions block calls from one LOtLBin to another).

In general vendors only provide detailed engines changes under the business portals. For home users only widely reported bugs notes are released. Under the hood changes affect the product internals many of which are patented. Nobody shares these.
