+# Test oldest and most recently supported, and versions with notable changes.
+# The last breaking change for a feature ansible-galaxy uses was in 0.8.0.
+# It would be redundant to test every minor version since 0.8.0, so we just test against the latest minor release.
+# NOTE: If ansible-galaxy incorporates new resolvelib features, this matrix should be updated to verify the features work on all supported versions.
