What was the reason for renaming it from ``hasAndBelongsToMany``?
Why not call it the more popular name ``manyToMany`` or ``isManyToMany``?

Somehow I feel changing an association name that CakePHP developers got used to to something that is a) new b) also not very descriptive and c) still not the name that would normally be used ("many to many") is not the right way.
