Rails 4.2.1 and 4.1.10 have been released!

After four release candidates, Rails 4.2.1 and 4.1.10 have finally been released! Thanks to all the contributors, for tons of fixes. Check out the full changes for 4.2.1 and 4.1.10 respectively.

New Stuff

bin/rails test runner

A new test runner – bin/rails test – has landed on master. This is the successor to the rake-based test runner, and includes a few rspec-inspired features that are not part of minitest, like running by line number, rerun snippets, or logs displayed with unicorns filled with rainbow colors.

Added rake initializers

Need to see all those initializers scattered in you application? Worry no more. Just run rake initializers! Did I mention they are sorted?

Improved

Use fullpath from Rack request

In Rack, request#fullpath returns the full path including the query string. This change uses fullpath from rack to avoid doing the same thing again in Rails. As a result, we also reduced some object allocations!

Fixed

Materialize subqueries by adding DISTINCT to suport MySQL 5.7.6+

In MySQL 5.7.6+, the default value for optimizer_switch has changed to derived_merge=on, which causes some issue with the subqueries generated by Rails. This change fixes that by adding a DISTINCT to the subqueries.

Don’t cast nil to string in postgres enums

Previously, nil values in PostgreSQL enums were casted to an empty string, which causes an error somewhere down the chain. But worry no more – this has now been fixed!
