The Penrose team is proud to announce the 0.9.9 release. Penrose is virtual directory server. Unlike a traditional directory server, virtual directory does not master the data itself in its own database. Instead a virtual directory will dynamically translate requests it receives to operations in other protocols or data models, such as to a relational database. It comes with Penrose Studio, a GUI-based administration and mapping tool based on eclipse RCP 3.1 platform. Check-out Penrose Studio flash demo here.

Highlights include:
Polling Connectors
Penrose Studio improvement
Embedding Penrose is now easier than ever
Various bug fixes and performance enhancements.

You can find more information in the release notes.
