Here're some heads ups for branch rearrangements:
1. There will not be any features checked into helix-0.6.x, except some
2. Master branch will be moved to helix-0.7.x for 0.7 version bug fixing.
3. Move helix-0.6.x branch to Master branch and try our best to make it
compatible with helix-0.7.x
Please let us know if you have any suggestions or questions regarding this!
