Ruby Enterprise Edition 1.8.6-20081205 released, thank you sponsors
Ruby Enterprise Edition (REE) is a branch of the official Ruby interpreter which is capable of reducing your Rails applications’ memory usage by 33% on average, as well as improving your applications’ performance. This is possible because REE includes copy-on-write enhancements for the garbage collector, as well as an improved memory allocator (tcmalloc). 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.
“We switched to enterprise ruby to get the full benefit of the [copy-on-write] memory characteristics and we can absolutely confirm the memory savings of 30% some others have reported. This is many thousand dollars of savings even at today’s hardware prices.” – Tobias Lütke (Shopify)
And just like Phusion Passenger, Ruby Enterprise Edition is 100% open source.
Recent developments
REE has just become better. We had been talking with DHH from 37signals about a possible sponsorship campaign for supporting REE development. The campaign has recently ended, and so we’re presenting the world with Ruby Enterprise Edition version 1.8.6-20081205.

Just wondering, when ruby 1.9.1 comes out, will there be a REE release that is for the 1.9.1 series, or does 1.9.1 make REE irrelevant?
