This is a quick release, cut mainly because publishing v1.17.6 to the Ubuntu PPA failed. It also carries a few fixes merged since then. Both v1.17.6 and v1.17.7 are ready for the Amsterdam fork on Sepolia (Oct 6, 2026), so Sepolia validators can run either version.
Users can now also choose their own history pruning point with --history.chain <block number>:<block hash>. It works both for pruning an existing node with geth prune-history and for snap sync, which then skips downloading the chain history before that block.
