A 3.7 update: Python 3.7.0b5 is now the final beta preview of Python 3.7,
the next feature release of Python. 3.7.0b4 was intended to be the final
beta but, due to some unexpected compatibility issues discovered during
beta testing of third-party packages, we decided to revert some changes
in how Python's 3.7 Abstract Syntax Tree parser deals with docstrings;
3.7.0b5 now behaves like 3.6.x and previous releases (refer to the
3.7.0b5 changelog for more information).

**If your code makes use of the ast module, you are strongly encouraged
to test (or retest) that code with 3.7.0b5, especially if you previously
made changes to work with earlier preview versons of 3.7.0.**

As always, please report issues found to bugs.python.org as soon as
possible. Please keep in mind that this is a preview release and its 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 is expected to become the
default version when 3.7.0 releases. Check it out!

The next (and final, we hope!) preview release will be the release
candidate which is now planned for 2018-06-11, followed by the official
release of 3.7.0, now planned for 2018-06-27. You can find Python 3.7.0b5
