I think the code looks good. I do have a few questions.

1. What's the next release that is mentioned in the warning? Does that include RC releases, or just the first stable release?
2. I only get the warning on the first call of workplane. I'm assuming this is normal behavior, but I wanted to confirm that, and to make sure that's the intended behavior. I'm fine with it if it is.
3. I get the following output:

>>> import cadquery as cq
>>> result = cq.Workplane("XY").workplane().box(1, 1, 1)
/home/jwright/Downloads/repos/cadquery/cadquery/utils.py:21: FutureWarning: Default walue of centerOption will change in next relase to ProjectedOrigin
  FutureWarning,

Why does the last FutureWarning have a trailing comma? Is there supposed to be more output after that?

I'd actually propose to release 2.0 soon, and change this in 2.1.

This is your local configuration I think - I cannot reproduce it.

I'm afraid this is the default (not so nice) formatting of the warning message showing the line of code where the warnining is invoked. I'd propose to leave as-is.

Sounds good. Do you want to merge, or should I?

[adam-urbanczyk]

I'll merge it.
