"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."
