Welcome to Prysm Release v4.0.8! This release is recommended. Highlights:

• Parallel hashing of validator entries in the beacon state. This results in a faster hash tree root. ~3x reduction #12639
• Parallel validations of consensus and execution checks. This results in a faster block verification #12590
• Aggregate parallel is now the default. This results in faster attestation aggregation time if a node is subscribed to multiple beacon attestation subnets. ~3x reduction #12699
• Better process block epoch boundary cache usages and bug fixes
• Beacon-API endpoints optimizations and bug fixes

Added

• Optimization: parallelize hashing for validator entries in beacon state #12639
• Optimization: parallelize consensus & execution validation when processing beacon block #12590
• Optimization: integrate LRU cache (above) for validator public keys #12646
• Cache: threadsafe LRU with non-blocking reads for concurrent readers #12476
• PCLI: add deserialization time in benchmark #12620
• PCLI: add allocation data To benchmark #12641
• Beacon-API: GetSyncCommitteeRewards endpoint #12633
• Beacon-API: SSZ responses for the Publishblockv2 #12636
