Welcome to v4.0.6 release of Prysm! This recommended release contains many essential optimizations since v4.0.5. Notable highlights:
- Better handling of state field trie under late block scenario. This improves the next slot proposer's proposed time
- Better utilization of next slot cache under various conditions
Important read:
1.) We use this opportunity to remind you that two different implementations of the underlying cryptographic library BLST exist.
- portable: supports every CPU made in the modern era
- non-portable: more performant but requires your CPU to support special instructions
Most users will want to use the "non-portable" version since most CPUs support these instructions. Our docker builds are now non-portable by default. Most users will benefit from the performance improvements. You can run with the "portable" versions if your CPU is old or unsupported. For binary distributions and to maintain backward compatibility with older versions of prysm.sh or prysm.bat, users that want to benefit from the non-portable performance improvements need to add an environment variable, like so: USE_PRYSM_MODERN=true prysm.sh beacon-chain prefix, or download the "non-portable" version of the binaries from the github repo.
2.) A peering bug that led to nodes losing peers gradually and eventually needing a restart has been patched. Nodes previously affected by it can remove the --disable-resource-manager flag from v4.0.6 onwards.
