Most changes to Python require a NEWS entry. Add one using the blurb_it web app or the blurb command-line tool.

If this change has little impact on Python users, wait for a maintainer to apply the skip news label instead.

I don't think this should be updated?

Suggested change

	__version__ = '1.0.10'
	__version__ = '1.0.9'

It was updated a couple of months ago in #122547, but the previous change was 10 years ago (b9f4fea), and there have been lots of updates in the past decade that didn't change it:

Is the module __version__ attribute really still needed? I thought that these were obsolete. If kept, is the use defined anywhere in a manner that would say when to bump it?

The issue quoted existing code for cmd in ('ver', 'command /c ver', 'cmd /c ver'):. Are all 3 options still needed for the Windows versions we currently support? Are any of these specific to Win95, ..., WinXp, etc?
