v5.0.1

This minor patch release has some nice improvements over the recent v5.0.0 for Deneb. We have minimized this patch release to include only low risk and valuable fixes or features ahead of the upcoming network upgrade on March 13th.

Deneb is scheduled for mainnet epoch 269568 on March 13, 2024 at 01:55:35pm UTC. All operators MUST update their Prysm software to v5.0.0 or later before the upgrade in order to continue following the blockchain.

Added

• A new flag to ensure that blobs are flushed to disk via fsync immediately after write. --blob-save-fsync #13652

Changed

• Enforce a lower maximum batch limit value to prevent annoying peers #13641
• Download blobs for checkpoint sync block before starting sync #13665 #13667 #13686
• Set justified epoch to the finalized epoch in Goerli to unstuck some Prysm nodes on Goerli #13695

Fixed

• Data race in epoch boundary cache #13680
• "Failed reorg" log was misplaced #13679
• Do not check parent weights on early fork choice update calls #13683
• Compute unrealized justification with slashed validators #13688 #13710
• Missing libxml dependency #13675

Security

Prysm version v5.0.0 or later is required to maintain participation in the network after the Deneb upgrade.
