Hi all,

If I was to start developing an application using Edge Rails with the  
view to deploying on Rails 1.1, would I fall foul of lots of bugs, or is  
it relatively stable?

I’d really like has\_many :through relationships, to save me dealing with  
HABTM + associations.

Thanks,

Tom

I develop all of my applications on Edge, and when ready to move to  
production I freeze the edge version it was last tested on.

Overall though, I have found it to be quite stable. There have been a  
couple  
occurrences, such as the loading issue which spun the Engines into a  
cyclical recursive loop. James has fixed this in the edge branch, but  
other  
instances may come into effect.

The trunk is a development version, so you can expect it to be a very  
rapidly changing environment. Which is stable if you are living in the  
moment 🙂

## Edge is reasonably stable, but we do change the API at a whim and without warning. So if you want to play with the latest, I encourage you to have a good test suite that’ll catch any bugs or API changes as you go along.
