Bump to version 3.2.5.
Added tag v3.2.5 for changeset cef745775b65
Issue #17980: Fix possible abuse of ssl.match_hostname() for denial of service using certificates with many wildcards (CVE-2013-2099).
#18600: add policy to add_string, and as_bytes and __bytes__ methods.

This was triggered by wanting to make the doctest in email.policy.rst pass;
as_bytes and __bytes__ are clearly useful now that we have BytesGenerator.
Also updated the Message docs to document the policy keyword that was
added in 3.3.
#18600: In 3.3, as_string does not accept a policy keyword.

Also, document the policy keyword that was added to Message in 3.3.
Null merge related to #18600.

For 3.3, we just deleted the example.  In 3.4 it was fixed.
Issue #18668: Further clarify m_size setting for non-negative values
Issue #18668: Further clarify m_size setting for non-negative values
Issue #16400: Add command line option for isolated mode.

 -I

    Run Python in isolated mode. This also implies -E and -s. In isolated mode
    sys.path contains neither the script’s directory nor the user’s
    site-packages directory. All PYTHON* environment variables are ignored,
    too. Further restrictions may be imposed to prevent the user from
    injecting malicious code.
