MongoDB Version 2.4 Released
A new version of the No-SQL DB MongoDB was released yesterday (Dec 22, 2010) it is mostly a bug fix release. All list of the addressed issues can be found here: http://jira.mongodb.org/browse/JAVA/fixforversion/10201
MongoDB (from "humongous") is an open source, scalable, high-performance, schema-free, document-oriented database written in the C++ programming language.
MongoDB combines the functionality of key-value stores - which are fast and highly scalable - and traditional RDBMS systems - which provide rich queries and deep functionality. It is designed for problems that are difficult to be solved by traditional RDBMSs, for example databases spanning many servers.
The database is document-oriented so it manages collections of JSON-like documents. Many applications can, thus, model data in a more natural way, as data can be nested in complex hierarchies and still be query-able and indexable.
I personally have used it, it was very easy to install and using Marc Escher's CFMongoDB (Link: http://cfmongodb.riaforge.org/) makes it extremely easy to utilize in ColdFusion.
