Updated all projects to atlasexternals-1.0.79. The changes wrt. atlasexternals-1.0.76 are (firstname.lastname@example.org...1.0.79):
It is the latter update that's relevant for 21.2. Pinging @mfenton, @afarbin, @whiteson, @jraine and @dbakshig.
Note that I don't use full-build for the CI, only full-unit-tests. I believe this should be enough (even too much) for this update...
