[RELEASE] Python 3.7.0rc1 and 3.6.6rc1 are now available

[Ned Deily]

Python 3.7.0rc1 and 3.6.6rc1 are now available. 3.7.0rc1 is the final
planned release preview of Python 3.7, the next feature release of
Python. 3.6.6rc1 is the the release preview of the next maintenance
release of Python 3.6, the current release of Python. Assuming no
critical problems are found prior to *2018-06-27*, the scheduled
release dates for 3.7.0 and 3.6.6, no code changes are planned
between these release candidates and the final releases. These
release candidates are intended to give you the opportunity to test
the new features and bug fixes in 3.7.0 and 3.6.6 and to prepare your
projects to support them. We strongly encourage you to test your
projects and report issues found to bugs.python.org as soon as
possible. Please keep in mind that these are preview releases and,
thus, their use is not recommended for production environments.
Attention macOS users: there is now a new installer variant for macOS
10.9+ that includes a built-in version of Tcl/Tk 8.6. This variant
will become the default version when 3.7.0 releases. Check it out!
