Hi Rail Core, It seems that partial_updates causes serialized attribute to be skipped when saving (unless *_will_change! is called first).
This causes previously working 2.0 apps to fail in none obvious, silent ways in 2.1.
I've written a minimalist patch (see ticket) to resolve this (and only this) and would greatly appreciate any feedback.
Thanks - Tom Lea
