Ruby Enterprise Edition 1.8.6-20090113 released

Ruby Enterprise Edition (REE) is a server-oriented distribution of the official Ruby interpreter, and includes various additional enhancements. REE’s main benefits are the ability to reduce Ruby on Rails applications’ memory usage by 33% on average, the ability to increase applications’ performance and the inclusion of various analysis and debugging features. The lower memory usage and increased performance are possible because REE includes - among other enhancements - a copy-on-write friendly garbage collector, as well as an improved memory allocator.

REE has been out for several months now and is already used by many high-profile websites and organizations, such as New York Times, Shopify and 37signals.
