v5.0.0

v5.0.0

Behold the Prysm v5 release with official support for Deneb on Ethereum mainnet!

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.

This release brings improvements to the backfill functionality of the beacon node to support backfilling blobs. If running a beacon node with checkpoint sync, we encourage you to test the backfilling functionality and share your feedback. Run with backfill enabled using the flag --enable-experimental-backfill.

Known Issues

• --backfill-batch-size with a value of 1 or less breaks backfill. #13646
• Validator client on v4.2.0 or older uses some API methods that are incompatible with beacon node v5. Ensure that you have updated the beacon node and validator client to v4.2.1 and then upgrade to v5 or update both processes at the same time to minimize downtime.

Added

API

• Support beacon_committee_selections #13503
• /eth/v1/beacon/deposit_snapshot #13514

Docker

• Docker images now have coreutils pre-installed #13564

Metrics

• da_waited_time_milliseconds tracks total time waiting for data availablity check in ReceiveBlock
  #13534
• blob_written, blob_disk_count, blob_disk_bytes new metrics for tracking blobs on disk #13614

Uncategorized

• Backfill supports blob backfilling #13595
• Add mainnet deneb fork epoch config #13601

Changed

Database

• --clear-db and --force-clear-db flags now remove blobs as well as beaconchain.db #13605

Flags

• EIP-4881 is now on by default. #13555

Fork Choice

Metrics

• gossip_block_arrival_milliseconds and gossip_block_verification_milliseconds measure in
  milliseconds instead of nanoseconds #13540
• aggregate_attestations_t1 histogram buckets have been updated #13607

p2p

• Reduce lookahead period from 8 to 4. This reduces block batch sizes during sync to account for
  larger blocks in deneb. #13599

Uncategorized

• Update gohashtree to v0.0.4-beta #13569
• Various logging improvements #13571 #13582 #13561 #13573 #13598 #13608 #13611 #13502 #13627

• Fix JWT auth checks in certain API endpoints used by the web UI #13565 #13568
• Return consensus block value in wei units #13575
• Minor fixes in protobuf files #13512
• Fix 500 error when requesting blobs from a block without blobs #13585
• Handle cases were EL client is syncing and unable to provide payloads #13597
• /eth/v1/beacon/blob_sidecars/{block_id} correctly returns an error when invalid indices are requested #13616

Fork choice

• Fix head state fetch when proposing a failed reorg #13579
• Fix data race in background forkchoice update call #13602

p2p

• Correctly return "unavailable" response to peers requesting batches before the node completes
  backfill. #13587

Slasher

• Many significant improvements and fixes to the prysm slasher #13549 #13589 #13596 #13612 #13620

V4.2.1

V4.2.1

Welcome to Prysm Release v4.2.1! This release is highly recommended for stakers and node operators, possibly being the final update before V5.

⚠️ This release will cause failures on Goerli, Sepolia and Holeski testnets, when running on certain older CPUs without AVX support (eg Celeron) after the Deneb fork. This is not an issue for mainnet
