# Overall configuration notes:
# - Artifact uploads for binaries are from GHC 9.2.7
# - Builds for Ubuntu happen on 22.04. We also include a single configuration
#   for 20.04 to increase our Linux coverage.
# - Docker builds happen nightly, on manual invocation, and on release branch commits
# Please update this comment as those details change.
