*** BREAKING CHANGE in JSON path expressions ***
Joni Freeman
There's one breaking change starting from Lift 2.3-M1 (not released
yet). Previous versions of JSON path expressions returned JField which
unnecessarily complicates the use of the expressions. If you have used
path expressions with pattern matching like:
val JField("bar", JInt(x)) = json \ "foo" \ "bar"
It is now required to change that to:
val JInt(x) = json \ "foo" \ "bar"
It is pretty easy to find those by grepping:
ack-grep JField | ack-grep '\\'
After upgrading from Lift 2.2 please analyze the hits you get with the
above grep.
The changeset:

Nice! It will require a lot of updating but will result in much less
cluttered code. Thanks for making this change.
