Upgrading

This version is binary compatible with the 2.0.0 version of the driver.

Updates and Improvements:

Update the cache for strings when reading and writing BSON documents. This reduces the memory needed for the cache by making it concurrent and switching to a single cache for the MongoClient instead of per-connection. For more information on the changes see the blog post.
The MongoClientConfiguration can now be observed via a PropertyChangeListener.
