Eager loading of dependent has_one associations won't delete the association #1212. Also, starting to refactor the tests to make them speedier, with optional support for transactional fixtures.

Fixed counter_sql when no records exist in database for PostgreSQL (would give error, not 0) #1039 [Caleb Tennis]

Fixed that HasManyAssociation#count was using :finder_sql rather than :counter_sql if it was available #445 [Scott Barron]

Fixed dependency reloading by switching to a remove_const approach where all Active Records, Active Record Observers, and Action Controllers are reloading by undefining their classes. This enables you to remove methods in all three types and see the change reflected immediately and it fixes #539. This also means that only those three types of classes will benefit from the const_missing and reloading approach. If you want other classes (like some in lib/) to reload, you must use require_dependency to do it.

Added replace to associations, so you can do project.manager.replace(new_manager) or project.milestones.replace(new_milestones) #402 [Tim Bates]
Added build and create methods to has_one and belongs_to associations, so you can now do project.manager.build(attributes) #402 [Tim Bates]
Fixed that Base#== wouldn't work for multiple references to the same unsaved object #402 [Tim Bates]
Added that if a before_* callback returns false, all the later callbacks and the associated action are cancelled. If an after_* callback returns false, all the later callbacks are cancelled. Callbacks are generally run in the order they are defined, with the exception of callbacks defined as methods on the model, which are called last. #402 [Tim Bates]
