- Move symbolic API to NNVM @tqchen
- Most front-end C API are backward compatible
- Removed symbolic api in MXNet and relies on NNVM
- Change of JSON format
- param and attr field are merged to attr
- New code is backward compatible can load old json format
- OpProperty registration now is deprecated
- New operators are encouraged to register their property to NNVM op registry attribute
- Known features removed limitations to be fixed
- Bulk segment execution not yet added.
- The gradient aggregation optimization hack by switching to addto is not yet added, can harm LSTM if it is constructed by unrolling the graph
This is the last release before the NNVM refactor.
