This issue introduces new features. I also move it from 1.0.1 milestone to 1.1.

[ysamouhos]

Same here. 28 days untill 1.0.1. Plenty of time and it's almost ready.

[sque]

I will not change them back to 1.1. But I think it is a mater of release policy that users should expect no new features or API changes in patch releases. Patch releases should be there to have an easy way and with no surprises upgrades.

As per release policy, this issue cannot be accepted in the next patch release. See more at #22 Moving to 1.1
