I''ve released Unicorn v0.2.1, the threadless fork of Mongrel optimized to run on UNIX/Linux in a LAN/localhost-only environment. It features nginx-style binary replacement without losing connections and should support all Rack and Rails v2.3.x applications. More information about Unicorn is available at: http://unicorn.bogomips.org/ Shortlog of changes since v0.1.0 are below: Eric Wong (10): Start _Known Issues_ section in README Allow binding to UNIX sockets relative to "~" tests: do not trust (our correct use of) 1.9 encodings gracefully die if working dir is invalid at fork Add signal queueing for test reliability Add unicorn_rails script for Rails 2.3.2 Documentation updates, prepare for 0.2.0 unicorn 0.2.0 unicorn v0.2.1, fix the Manifest == Disclaimer There are no known production instances of unicorn deployed anywhere in the world. The original author of unicorn only has one, internal, low-traffic Sinatra application deployed with it. Maybe you''ll be the first guinea pig to test it in production. Of course there is NO WARRANTY whatsoever if anything goes wrong, but let us know and we''ll try our best to fix it. -- Eric Wong
