This is a maintenance release with several important bug fixes. Notably, a critical issue in debug_executionWitness could previously corrupt node data, users relying on this RPC endpoint are strongly advised to upgrade.
Geth now also supports syncing with chains where pre-Prague history has been pruned, and allows explicitly removing it via geth prune-history --history.chain postprague.
