Ruby 1.9 Released
As is tradition, the latest version of Ruby was released on the 25th December. Ruby 1.9 is a development release intended to help developers make sure their code works before Ruby 2.0 and should not be rolled out into production; there are still some bugs that need to be worked out.
This release is still significant as it’s the first new release to run on the YARV virtual machine. Computationally expensive Ruby can expect some nice speed improvements. There are also a significant number of core API and some syntax changes and they are all covered in this extensive Ruby 1.9 changelog.
