+1, seems sensible to me.

Thanks @jhorwit2

[otoolep]

Can you also update the 0.9.3 CHANGELOG and give yourself credit?

[jhorwit2]

Yup. I'll do that now.

[jhorwit2]

This should be under bug fix right?

[otoolep]

Yeah, bug fix makes sense to me.

[jhorwit2]

@otoolep anyone idea when this will be merged? Keeping conflicts with changelog file up to date is tedious haha.

+1 Thanks @jhorwit2!
