Whither 14.0.6?

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, --Mike
