Time for a new release?

[darwin67]

Hello,

First of all, thanks for the great library!

It has been more than 6 months since 0.4.19 was released, and it would be great if you could cut a new release so we could utilize some of the recent changes.
e.g. #506 is something I'm interested specifically

Thanks

We are now quite a few releases further, I think this issue can be closed.
