Comment (by JGoldstone):

 Thanks for keeping me Cc:'d, and of course I saw the discussion over on
 the OpenEXR list. You saw the email from Nick and from Larry; I would make
 the analogy to Python, with a yearly release that has (typically) some ABI
 changes and is reflected in the second digit, and considerably more
 frequent, ABI-preserving changes in the third digit. For us to change the
 first digit, which Larry mentions as being 'more major than major' — that
 would be the equivalent of the Python 2 -> Python 3 transition. Or close.
 I don't think we've permanently foresworn the idea, as they seem to have,
 but like them we can't envision anything that would be sufficiently earth-
 shaking.

 But I'm bothering to add a comment here mostly to thank you, to express my
 extreme gratitude that MacPorts is tracking OpenEXR (and other ASWF
 projects, I believe) closely again.
