Ruby 1.9.1 released

Janwedekind writes: "According to Ruby Inside Yuki Sonoda yesterday announced the release of Ruby 1.9.1. The VM of Ruby 1.9 (formerly known as YARV) was initiated by Koichi Sasada and has been in the making for quite some time. Yukihiro Matsumoto (the creator of Ruby) already presented many of the upcoming features in his keynote at RubyConf 2007. Most notably Ruby 1.9 now supports native threads and an implementation of fibers. A lot of work also went into encoding awareness of strings. It will take some time though until the majority of existing Ruby-extensions get ported to 1.9."
