0.13 can indeed open v2 notebooks, although it only saves in v3, so it's
not practical to use 0.12 and 0.13 together. But we intend to keep
compatibility for much longer now - the v3 format was designed to allow
much more extension without breaking the ability of 0.13 to read it. This
came up in the discussion around standardising the Scipy stack as well.
There we said that if we have to break compatibility again, we will need to
have an overlap period where IPython can read the new format, but still
saves in the old format by default.

Obviously the notebook is still quite young and rapidly developing, but we
see the format break from 0.12 to 0.13 as the exception, not the rule. If
you decide to use it, make sure everyone starts with at least 0.13.

That's great news about the scientific computing curriculum. Good luck with
training more people in Python!

Best wishes,
