Hi Mike,


That does appear to be the current general approach, but I'd suggest 
changing it.

Because in the last week before release we shouldn't be chasing new 
versions of unrelated software, in my opinion.


Fortunately the switch to Ubuntu 20.04 hasn't happened yet, and is due 
to be rolled out beginning November 30th 
(https://github.com/actions/virtual-environments/issues/1816). The CI 
pipeline has a set of warnings: "##[warning]Ubuntu-latest pipelines will 
use Ubuntu-20.04 soon. For more details, see 
https://github.com/actions/virtual-environments/issues/1816"
