Summary

This is a hotfix release addressing several bugs and performance issues discovered in v8.0.0.

Notable changes:

• From the Fulu fork, checkpoint blobs will no longer be downloaded from the checkpoint server and instead they will be fetched from p2p peers. The getBlobSidcars Beacon API is deprecated from Fulu and clients may drop support in future releases. (#8413, #8417)
• Prevent unnecessary state advances pre-Fulu. This improves beacon node performance prior to the Fulu fork. (#8388)
• Fix rare custody context initialization race condition that could cause panics. (#8391)

As a reminder, all mainnet users must upgrade to either v8.0.0 or v8.0.1 prior to the Fulu fork at epoch 411,392 (2025-12-03, 21:49 UTC). You must also update your execution client (e.g. Geth, Nethermind, Erigon, Besu or Reth).

For users upgrading from v7.x.x, please see v8.0.0 release notes here.
