  That should be fine, subject to some issues.

  Use 3.2.0.  There's been a number of fixes, including for TLS 1.3.  And Windows 11 tries hard to use TLS 1.3.

  That is, we're not going to debug issues *again* when they've already been found and fixed.  If the issue is still there with 3.2.0, then we can spend some time tracking it down.  But we haven't seen issues yet in our tests.
