Platform Development • Re: XULRunner still uses Python 2

Basically, from 34.3.0 onwards we'll be on Python 3 -- exact range seems to be 3.7 through 3.13(?) and no real handle on breaking changes beyond that, because we had to pick something... got to love moving targets ;P

Forgive me if I am wrong but I thought that the version of mozilla-build we use ships Python 3.6.
