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…
This is a maintenance release with a number of performance improvements to block processing and initial sync, and is recommended for all users. A few things worth highlighting: The Amsterdam hardfork is scheduled on the Sepolia testnet at timestamp 1791294816 (Oct 6, 2026, 13:53:36 UTC). Sepolia node operators must upgrade before that time. The Holesky testnet has been removed, as the network reac…
This is a maintenance release with accumulated bug fixes and improvements, and is recommended for all users. It continues the implementation work for the upcoming Amsterdam hardfork. A few things worth highlighting: The default GOGC has changed from 20 to 50, trading a higher memory peak for less GC overhead. Set --gogc=20 to keep the old behavior. Pebble v2 is now supported as a key-value store b…
