Since Cats v2.13.0 the following rewrites can be recommended:

• sequence_ -> sequenceVoid
• traverse_ -> traverseVoid
• nonEmptySequence_ -> nonEmptySequenceVoid
• nonEmptyTraverse_ -> nonEmptyTraverseVoid
• parSequence_ -> parSequenceVoid
• parTraverse_ -> parTraverseVoid
• parNonEmptySequence_ -> parNonEmptySequenceVoid
• parNonEmptyTraverse_ -> parNonEmptyTraverseVoid
