Having looked at it overnight I can see that the new stuff in 2.3 treats habtm just like hm. So that if for example you have many users and many roles and many-to-many relationship between them and you try to use the new stuff to add a role to a user from a select list it will add a copy of the role to the roles table. If you've got a unique index on the non id identifier, like the name, then you'll be in trouble. It will also issue updates to things it shouldn't. I've cleaned it out of my code. But the jscript stuff in the examples for adding new records is quite useful, I'm fiddling with it now to make it work with old-style nested forms for adding m-2-m links.
