Rails 0.12 - gone are the days of piggy back April 19th

Three weeks after Rails 0.11 had seen the light, Version 0.12 goes airborne with a total of 96 changes, tweaks and fixes.

The highlight of this release surely are eager associations. This technique reduces the amount of queries hammering on your SQL server to 1 (one) in most cases without resorting to writing of manual queries. Alongside of this, the existing `find_all` and `find_first` methods have been deprecated in favor of a more flexible `find` method with named parameters. More of this can be found in the updated API docs.

Additionally, Unit testing has been simplified and more Ajax effects have been added. Best of all: Upgrading doesn’t require any code changes at all. The typo tests ran just fine after doing a `gem update rails`.

(Update 04/20: Several bugs were found when putting the 0.12 release into production use at various sites which made 0.12.1 hit the shelves this morning. Be sure to upgrade.)
