Since Microsoft JDBC Drivers 4.2 for SQL Server, it is supported Java SE Development Kit (JDK) 8.0 and Java Runtime Environment (JRE) 8.0.
The support for the specific API Java Database Connectivity (JDBC) has been extended to include API JDBC 4.1 and 4.2.

Latest release is 1.3.1 and is dated 2013-06-08 and it is JDBC 3.0 (a type 4 driver)

Currently we are using Hibernate 4.1.12.Final
