[Python-Dev] PEP 407: New release cycle and introducing long-term support versions

[Matt Joiner]

If minor/feature releases are introducing breaking changes perhaps it's
time to adopt accelerated major versioning schedule. For instance there are
breaking ABI changes between 3.0/3.1, and 3.2, and while acceptable for the
early adoption state of Python 3, such changes should normally be reserved
for major versions.

If every 4th or so feature release is sufficiently different to be worth of
an LTS, consider this a major release albeit with smaller beading changes
than Python 3.

Aside from this, given the radical features of 3.3, and the upcoming Ubuntu
12.04 LTS, I would recommend adopting 2.7 and 3.2 as the first LTSs, to be
reviewed 2 years hence should this go ahead.
