Changes:
JaQu (Java Query), a tool similar to LINQ (Language Integrated Query from Microsoft) is now included. Deadlocks are now detected. Compatibility with other databases such as Oracle or Apache Derby has been improved. Java methods can now be overloaded. It is no longer allowed to create columns with the data type 'null'. Opening large databases was sometimes very slow.
