Nimbus v23.8.0 is a low-urgency upgrade focusing on performance and stability improvements, aiming to address the increasing number of validators on mainnet and upcoming testnets such as Holesky.
Please note that this version enables the new attestation subnet subscription logic, proposed in the Ethereum 1.4 consensus spec. This will significantly reduce the CPU usage and the consumed network bandwidth on beacon nodes with many validators, but it will slightly increase them on nodes with a single validator. The --subscribe-all-subnets option can still be used on powerful hardware configurations to produce potentially more profitable blocks by processing all attestations directly instead of relying on aggregators.
The upgraded BLST library now identifies your CPU model and selects
the most efficient instruction set at run-time which significantly
speeds up docker and binary builds. We have tested this on a wide range
of hardware, but should the CPU incorrectly advertise extensions it does
not have, a downgrade might be necessary while we investigate.
