They slapped a bunch of ES's that were already written into the product. As I said years ago, they would just drip out extended solutions that they paid a few million for, on a product that grosses 60m/year in maintenence. Other than scraping SQL into the product (0 optimization in SQL Server), I see virtually no new code other than upgrading a few things to BF and testing.
Anybody have a feel for the 4.6 game plan? Without hiring pvx programmers, they are running out of hats to pull a rabbit out of.
