Hold on a sec – this will be strong mode broken until the associated SDK release
comes out, right?

Do we want to hold off until a dev release of 1.21?

[Lasse Reichstein Nielsen, 2016-10-13 16:28:18]

I think this should qualify for a minor version update on the version number.

To stay compatible, we could update the SDK-dependency to >=1.21.0, so the
changes are synchronized.

[floitsch, 2016-10-14 09:32:33]

Updated sdk dependency.

I don't think this is necessary, since this tracks a core library change.

It's still a backwards compatible change to the API. Semantic versioning doesn't
make exceptions for changes inherited from other packages.

It's a visible change (that shouldn't make a difference, but still).
I don't think it hurts to bump the number.
Changed to 1.10.0
