This release comes with new monitoring support to collect runtime statistics about performance relevant behavior and state. Statistics are published through the Performance Counters API. You can now use the PerfMon monitoring tool to view graphed information about queries, the free space manager, the object reference system, IO, and networking. Since this is still a work in progress, you may expect to see changes in the API and the list of actual statistics supported.

This release comes with an optimized
implementation of LINQ (Language INtegrated
Queries). Solution files for Visual Studio 2008
are provided along with the sources. The latest
work on Transparent Activation (TA) and
Transparent Persistence (TP) is included. Db4oTool
was improved to make optimization for Native
Queries and for TA/TP easier. Optimizations can
also be called with msbuild.
