ethereum/go-ethereum v1.17.2

EMF Suppressor (v1.17.2)

on GitHub

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.
