What is the EOL date for Rails 2.3?
回答1:
2.3 reached EOL on 2013-06-25, when rails 4.0.0 was released.
Only the "last major release series" will receive patches, according to Michael Koziarski. Therefore, when 4.0 was released, 2.3 stopped receiving patches.
The rails team had hoped to drop support for 2.3 much earlier. On 2011-12-29 Aaron said:
.. we have no plans of releasing another version of 2.3 [beyond 2.3.14]
Before that, on 2011-06-08, Aaron said:
This branch [2.3] is in security-maintenance mode. We will release it when there are problems like "the sky is falling", or major security issues. It's time for us to focus on pushing Rails forward!
回答2:
There is a commercial service that will continue to provide security patches for Rails 2.3 after the version has reached EOL (when Rails 4 is released).
