Hi everyone,
I am happy to announce that Rails 4.0.1.rc1 has been released. This is a bug fix release and includes more than 450 commits.
This release comes up with an important change on how Active Record handles subsequent order calls.
In Rails 4.0.0 when you do something like this:
User.order("name asc").order("created_at desc")
The later called order will be prepended in the ORDER BY clause resulting on this SQL:
SELECT * FROM users ORDER BY created_at desc, name asc
In Rails 4.0.1 the behavior of Rails 3 has been restored and the generated ORDER BY clause looks like this:
SELECT * FROM users ORDER BY name asc, created_at desc
We chose to revert the behavior because it added a major backward incompatibility that made harder to have an upgrade path without major changes in the application code. So we took the most conservative path of reverting it to be consistent with the idea of having a smoother upgrade path to Rails 4.
Also, this release adds some performance improvements to make Rails 4 even faster.
If no regressions are found we will release 4.0.1 final this Tuesday, on October 22, 2013. If you find one, please open an Issue on GitHub and mention me (@rafaelfranca) on it, so that we can fix it before the final release.
