.. versionchanged:: 3.7.2
Windows now uses redirector scripts for ``python[w].exe`` instead of
copying the actual binaries, and so :meth:`setup_python` does nothing
unless running from a build in the source tree.
In addition, :class:`EnvBuilder` provides this utility method that can be
called from :meth:`setup_scripts` or :meth:`post_setup` in subclasses to
assist in installing custom scripts into the virtual environment.

@ -2512,3 +2512,13 @@ In 3.7.1 the :mod:`tokenize` module now implicitly emits a ``NEWLINE`` token
when provided with input that does not have a trailing new line. This behavior
now matches what the C tokenizer does internally.
(Contributed by Ammar Askar in :issue:`33899`.)
Notable changes in Python 3.7.2
===============================
In 3.7.2, :mod:`venv` on Windows no longer copies the original binaries, but
creates redirector scripts named ``python.exe`` and ``pythonw.exe`` instead.
This resolves a long standing issue where all virtual environments would have
to be upgraded or recreated with each Python update. However, note that this
release will still require recreation of virtual environments in order to get
the new scripts.
