Description of change

[cclauss]

Related to #1849 ?

[roryqueue]

yes, relates-- sorry at work and not able to dig further atm, but that change seems to fix

[roryqueue]

(or rather, obviously doesn't work given it's failing, but the regex change matches both 9.X and 10.X, where as the other one fails on 10.X, so could be a hint to a real fix)

[rvagg]

Sorry, I'm not a python person but this looks invalid to me, \d+ will match double digits just as well as \d?\d in any normal regex engine. Can I close this or is someone willing to dispute that Python does something funky with regexes that makes this necessary?

[cclauss]

Can we just replace this line with version = ".".join(version.split(".")[:3]) and move on? Not a fan of regex for trivial use cases.

[cclauss]

I believe that #1890 fixed this. Please rebase and reverify.

[cclauss]

Conflicts to resolve.

I think this is dealt with already and the solution posed here isn't correct as far as I can tell
