Modularized Association Methods in Rails 3.2
Happy Friday! It's Rails 3.2 day! The official release announcement mentions a few of the big changes, but I'd like to take a moment to highlight a relatively small change I was responsible for, one that I hope may make your life a little easier.

Limitless Strings for PostgreSQL
We all love ActiveRecord migrations and the sexy DSL for declaring fields. OK, I don't know if you do, but I sure do.
But life isn't perfect (don't get me started), and there's various details that make using the migration DSL a bit of
a pain.
