New Early Access builds

[Christian Stein]

No, I didn't see them before.

A similar run 3 weeks ago using 16-loom+7-285 [1] didn't emit
those warning messages. A second run today [2] produced them, too,
but fewer in numbers, methinks.

Will keep an eye on those warnings, as GitHub will upgrade their
"Linux boxes" to run Ubuntu-20.04, soon [3].
