See #535 (comment): The plan is to skip Node 0.12.7 and (eventually) target Node 4.0 (which is already released).

@brodybits this work is for upcoming 0.3.x. I'm almost finished with Chakra (v8 3.28+) support. We will be adding missing API (comparing to 0.12) to 0.3.x series until 0.4.x is ready.

[obastemur]

better merge new API into 0.3.1.x (since we are updating the API) IMHO, It's important not to add anything breaking node 0.10.x compatibility.

👍

Also adding a reference to #402 where Node 0.12.x was discussed before. Nice to include whatever we can from 0.12.

@karaxuna can you mark the ones (on comparison list) already part of 0.3.1.0 ?

Implemented with #582 .
