The Python build factories have been busy the last several weeks preparing
our fall lineup of releases.  Today we are happy to announce three
additions: 3.6.3rc1, 3.7.0a1, and 3.3.7 final, which join last weekend's
2.7.14 and last month's 3.5.4 bug-fix releases and 3.4.7 security-fix
update (https://www.python.org/downloads/).

1. Python 3.6.3rc1 is the first release candidate for Python 3.6.3, the next
maintenance release of Python 3.6.  While 3.6.3rc1 is a preview release and,
thus, not intended for production environments, we encourage you to explore
it and provide feedback via the Python bug tracker (https://bugs.python.org).
3.6.3 is planned for final release on 2017-10-02 with the next maintenance
release expected to follow in about 3 months.  You can find Python 3.6.3rc1
and more information here:

2. Python 3.7.0a1 is the first of four planned alpha releases of Python 3.7,
the next feature release of Python.  During the alpha phase, Python 3.7
remains under heavy development: additional features will be added
and existing features may be modified or deleted.  Please keep in mind
that this is a preview release and its use is not recommended for
production environments.  The next preview release, 3.6.0a2, is planned
for 2017-10-16.  You can find Python 3.7.0a1 and more information here:

3. Python 3.3.7 is also now available.  It is a security-fix source-only
release and is expected to be the final release of any kind for Python
3.3.x before it reaches end-of-life status on 2017-09-29, five years after
its initial release.  Because 3.3.x has long been in security-fix mode,
3.3.7 may no longer build correctly on all current operating system
releases and some tests may fail.  If you are still using Python 3.3.x,
we **strongly** encourage you to upgrade now to a more recent, fully
supported version of Python 3.  You can find Python 3.3.7 here:
