Hi all,

Is there a way to have a list of all deprecated methods or classes in  
each new versions of Rails? I know that a warning is logged sometimes,  
but I would like a proper list to analyze the deprecated parts of my  
code before running it.

Thanks,  
Benoit C.

Thanks for the link. A good use of ack-grep on the rails gems:  
rails-2.0.5  
actionmailer-2.0.5  
actionpack-2.0.5  
activerecord-2.0.5  
activeresource-2.0.5  
activesupport-2.0.5

gave me what I was looking for.
