The major change between Raft v1.6 -> v1.7 was the introduction of the Prevote feature. Before Prevote, when a partitioned node rejoins a cluster it may cause an election even if the cluster was stable. Prevote can avoid this useless election so reintroducing partitioned servers to an otherwise stable cluster becomes seamless. Full details: hashicorp/raft#530 In #20335 we discussed whether or not to add a configuration option to disable prevote in case bugs were discovered. While bugs have been found (hence the v1.7.1 version as opposed to v1.7.0), I'm choosing to follow Vault's lead of straightfordwardly bumping the raft dependency: hashicorp/vault#27605 and hashicorp/vault#28218
