Editing Ruby (programming language) (section)

=== Ruby 1.8 and 1.9 ===

Ruby 1.8 was initially released August 2003, was stable for a long time, and was retired June 2013.<ref name="1.8.7-retirement"/> Although deprecated, there is still code based on it. Ruby 1.8 is only partially compatible with Ruby 1.9.{{cn|date=April 2025}}

Ruby 1.8 has been the subject of several industry standards. The language specifications for Ruby were developed by the Open Standards Promotion Center of the Information-Technology Promotion Agency (a [[Government of Japan|Japanese government]] agency) for submission to the [[Japanese Industrial Standards Committee]] (JISC) and then to the [[International Organization for Standardization]] (ISO). It was accepted as a Japanese Industrial Standard (JIS X 3017) in 2011<ref name="JIS X 3017"/> and an international standard (ISO/IEC 30170) in 2012.<ref name="IPA"/><ref name="IEC 30170"/>

Around 2005, interest in the Ruby language surged in tandem with [[Ruby on Rails]], a [[web framework]] written in Ruby. Rails is frequently credited with increasing awareness of Ruby.<ref name="Devarticles"/>

Effective with Ruby 1.9.3, released 31 October 2011,<ref name="Ruby 1.9.3"/> Ruby switched from being dual-licensed under the Ruby License and the GPL to being dual-licensed under the Ruby License and the two-clause BSD license.<ref name="license-change"/> Adoption of 1.9 was slowed by changes from 1.8 that required many popular third party [[#Repositories and libraries|gems]] to be rewritten.{{cn|date=April 2025}}
