Hi, I’ve been cruising along trying to upgrade a rails 2.0.2 app to  
2.2.2, but first made a pit stop at 2.1.2 based on some posts that I  
read.

Are there any tutorials, guides etc… on how to keep the plugins  
compatible with the latest version of Rails that I’m on? How would I  
know what version of say attachment\_fu was most compatible with 2.1.2?  
If I grab the latest version of the plugin it might work for 2.2.2 but  
not 2.1.2 etc…
