Thanks for linking to the new Asset Pipeline guide. Richard Hulse, Mohammed El-Abid and me put a lot of work into that to try to help people understand how it works.
It's just a fantastic feeling to see something that I've worked on be helpful to so many people. Thank you.
Thanks for the links. From reading the release notes, it looks like there's a lot of changes around the behavior of creating/updating/destroying through active record associations - other than the release notes is there anywhere else that has a good writeup of these changes?
