Ruby Weekly Issue 134
February 28, 2013
From the Editor's Desk..
Last Sunday marked the 20th anniversary of work commencing on Ruby way back in 1993 and it was celebrated in style with the final release of Ruby 2.0.0. Congratulations to Matz along with the rest of the core team and anyone else who has contributed over the years to the rich Ruby ecosystem we enjoy today. Now.. on to an extremely release heavy issue.
Ruby 2.0.0-p0 Released on Ruby's 20th Anniversary
A big development in the Ruby world that can't be summarized in one link, so we have a whole Ruby 2.0 section further down ;-) As well as the usual ways (direct, RVM, ruby-build), Ruby 2.0 is also available via Bitnami's Ruby Stack and on Windows through RubyInstaller.
Rails 4.0 Beta 1 Released
Not content to let us play with Ruby 2.0 for too long, Rails has gotten in on the release action with the first beta of the long awaited 4.0. DHH summarizes the update for us here.
Ruby 1.9.3-p392 Released
Ruby 1.9.3 gets an update to address more security vulnerabilities, this time in REXML (the XML parser in the standard library) and the JSON library. Upgrade your 1.9.3 to this, even if you're not headed to 2.0 yet.
JRuby 1.7.3 Released: Primarily Addresses 2 Security Issues
Also released via Bitnami's JRuby stack if you want a complete stack out of the box.
