Long term support for Ruby on Rails 2.3, 3.2, and 4.2

After a few years of service, old versions of the Ruby on Rails framework reach end-of-life. At this point the volunteer team that maintains Rails will no longer provide security patches against criticial security incidents.When community support for a popular version of Rails ends, Rails LTS takes over maintenance and continues to provide security patches. When a new advisory is posted to the official Rails security list or reported to us directly, we will patch the vulnerability and release a new version of the Rails LTS gems.
