[Wheel-builders] PEP 571 - manylinux2

[Mark Williams]

Hello, wheel builders!

I had a chat with Geoffrey Thomas about the particulars of symbol
versioning and he reminded me that you all would be interested in a
successor to manylinux1.

Here's the PEP so far:

https://github.com/python/peps/blob/master/pep-0571.rst

And the associated distutils-sig thread:

https://mail.python.org/pipermail/distutils-sig/2018-February/031944.html

(note I sent the first email twice from two different addresses :( The
text of the PEP is the same, so you only have to read one!)

And here are the PRs:

https://github.com/pypa/manylinux/pull/152
https://github.com/pypa/auditwheel/pull/88
https://github.com/pypa/pip/pull/5008

I put initial Docker images up here if you'd like to repair a wheel or
two:

Highlights from the distutils-sig thread and pypa/manylinux PR so far:

- Should `manylinux` use CalVer (http://calver.org) ?

- Can the next `manylinux` use newer compilers than `manylinux1`
  without implying backwards incompatibilities?  (The answer is yes -
  explanation forthcoming, thanks to Geoffrey for the help!)

- Should the next `manylinux` drop support for i686?

Please feel free to join the discussion on distutils-sig or comment on
the various PRs.  I look forward to collaborating with everybody!
