And they change a lot things in 2.2...again

hi
Again any subtencial change in 2.2 that need app code update
this time in 2.2
before a setRecord or Update record:

params = { resource:[ params ]}
was in 2.1
params = { "resource":[ params ]}

Remember that this kind of change need code recertification when we upgade from 2.1 to 2.2

and in 2.2 mongo db $date is not working anymore...
for ex
item = {
_id:myId,

ISOLastLogin : { "$date": now },

}
any idea ?

thanks
