I see 14.0.5 on Tim's server but it doesn't support Buster.

I see 14.0.7 PSB on Slávek's server but there are problems with
multiple displays and the churn rate is too high for our production
use.

I see another place which may have 14.0.6 but is restricted to
developers only and which I'm not specifying here because of
a possible security issue.

I can't find 14.0.6 stable, other than some Ubuntu CD images.

Whither 14.0.6 stable repository?

TIA,
