Version 2.2.18
Added API functions to retrieve information on indexed properties managed by the embedding layer. Fixes bug 737.
Make ES5 Object.defineProperty support array elements. Fixes bug 619.
Add heap profiling to the API.
Remove old named property query from the API.
Incremental performance improvements.
