Since you wrote "Any other opinions?" I assume you intended to send
this to the list... (My reply follows below.)

Thank you for those corrections.
In addition, I've tweaked it some more and I added a sentence at the
beginning to "introduce" Python, to avoid assuming knowledge.
Question: Some Python scripts have not been updated for Python 3.x
yet. Should those be listed in the release notes under "Known Issues"?
Should a bug be filed? Or both?
The updated text:
[[[
Support for Python 3.x:
Some optional features of Subversion utilize the Python scripting
language.
Subversion's SWIG Python bindings and automated test suite now support
Python 3.x (and newer).
Support for Python 2.7 is being phased out:
As of 1 January 2020, Python 2.7 has reached end of life. This means
that Python 2.7 will no longer receive maintenance releases or
patches, even for security issues. All users are strongly encouraged
to move to Python 3.
As Subversion 1.14 is a Long Term Support (LTS) release with planned
support into 2024, well beyond end-of-life for Python 2.7, the
Subversion developers cannot commit to supporting and testing with
Python 2.7, or to fixing bugs that affect Python 2.7 only, for the
duration of this support period.
This means that although Subversion 1.14.0 still technically works
with Python 2.7, any later 1.14.x point release may drop this support
if it becomes too difficult to maintain.
If you must continue using Python 2.7, our previous Long Term Support
release, Subversion 1.10, is supported until 2022. Python 2.7 support
will not be removed from Subversion 1.10.
Note that Subversion does not require Python for its basic operation.
If you are not using Subversion's SWIG Python bindings, automated test
suite, or other Python-coded tools that ship with Subversion, this
change does not affect you.

All thoughts / observations / criticisms welcome...
