Fix some deprecation warnings

Note this is against teh/constrained

Sorry, we cannot merge more PRs regarding teh/constrained before #303 is completed.

(just kiddinng ofc, though I actually started the process of bringing that up to date just yesterday!)

Are you ok with the v0.5 failures? Then maybe you should update the travis file. Not that anyone but you and your lab would really care, but... Then you get to see the green check mark!

That's great to hear! Do keep in mind that because #303 won't actually be useful to my lab (at least, not for our "main" need) and I already maintain far too many other packages, it's pretty much up to others to keep it working and fix bugs. If you have questions about how it works I can hopefully help answer them.

[pkofod]

Do you want me to merge it?

[timholy]

Yes please. (I don't have permission.)

[pkofod]

Must have happened in the org move. I’ll have a look at it later
