FoundationDB 2.0 combines the power of ACID transactions with the scalability, fault tolerance, and operational elegance of distributed NoSQL databases. This release was driven by specific customer feedback for increased language support, network security, and higher-level tools for managing data within FoundationDB.
Along with the additional language and layer support, 2.0 also ships with full Transport Layer Security which encrypts all FoundationDB network traffic, enabling security and authentication between both servers and clients via a public/private key infrastructure.
Also in 2.0, monitoring improvements report more detailed information about potential low-memory scenarios even before they happen.
FoundationDB 2.0 is backwards-compatable with all previous API versions, so any code that you wrote against an old version of FoundationDB will still run; there have been minimal API changes so updating your code to the new API version will be a snap.
