I have rails 1.2.3 and 1.2.5 installed, and i’m using 1.2.5 as standard.  
I’m having some restful issues. I want to make a new app, frozen to  
1.2.3, so i can see if the problems occur there as well. Can anyone  
tell me how to do this please? I can only find out how to freeze to  
edge, and that’s no good for me.

thanks!

rake rails:freeze:edge # Lock to latest Edge Rails or a specific  
revision  
with REVISION=X (ex: REVISION=4021) or a tag with TAG=Y (ex:  
TAG=rel\_1-1-0)

so…

rake rails:freeze:edge TAG=rel\_1-2-3
