---------------------------------------
+1. 2.2.0 adds support getting the length of an array, which I could really use
right now...

>
> JsonPath (https://github.com/jayway/JsonPath) has a new release.
> Given some of the optimizations that were made for the processors to provide
> caching of and validation without exceptions of expressions, it is not a
> clean upgrade due to those library internals being removed and/or changed.
> Additionally, a new caching mechanism for expressions was also provided that
> may be beneficial to make use of.
