I have written before about the method find_or_create_by, so what is different about this new addition and why is it needed?

UPDATE 2018! Paperclip is deprecated

This release offers some cool updates. It’s clear that everybody is concerned about what happened at GitHub a while back, when someone managed to access everybodys ssh keys by using mass-assignment to change his permission. So it’s nice to see that the Rails community is addressing this. I really like that the auto-generated ActiveRecord models have been updated to show the importance of attr_accessible. Since a lot of people who are using rails can be fairly new to developing. For some it might even be the first thing the try. So unless they understand the risks, they might end up with an application with some serious security risks.

Yehuda Katz has started a KickStarter project were he explains his plans to develop an .app for Mac OS X that will be used to quickly get up and running with Rails. He mentions how it used to be (in the good old days) and goes on to describe what this project will accomplish. The pledge goal for the project is set to $25,000.
