OffchainLabs/prysm - v7.1.4 New

Published: May 22, 2026

Release Summary

Prysm version 7.1.4 is a maintenance release that introduces significant progress on the upcoming Gloas fork implementation, alongside important performance improvements and production fixes. Node operators can update at their convenience.

Gloas Fork Preparation

This release makes substantial headway in preparing for the Gloas hard fork (ePBS), with many core components now wired up in preparation for devnet testing. Key advancements include:

Payload Timeliness Committee (PTC): Full end-to-end support for PTC duties has been added. This includes a pool for aggregating `PayloadAttestationMessage`s, which attest to the timely arrival of execution payloads and a validator's data availability.
P2P Block Building: The infrastructure for a peer-to-peer block building market is taking shape. This includes the implementation of gossip topics, verification logic, and caches for `signed_proposer_preferences` and `execution_payload_bid`. Proposers can now select the highest P2P bid over a self-built block.
Builder Lifecycle: Logic for handling builder voluntary exits and processing builder-related deposits has been implemented.
Observability: A wide range of initial observability metrics for Gloas have been added across forkchoice, sync, the validator client, and state processing to monitor the new fork's behavior.

Performance and Optimizations

Major Memory Reduction: The in-memory representation of a validator has been compacted from ~264 bytes to ~128 bytes. This significantly reduces memory usage, saving an estimated 300–450 MB of heap memory on mainnet and lowering garbage collection pressure.
CPU Spike Fix: An issue causing periodic high CPU usage has been resolved. The fix eliminates expensive state replays that occurred when computing sync committee members, which was especially noticeable at the start of a new sync committee period.

Key Fixes

Missed First Attestation: A bug has been fixed where newly-activated validators could miss their very first attestation when the validator client was run with the --enable-beacon-rest-api flag.
Crash Fix: A nil panic in the fetchOriginSidecars function has been resolved. This could occur when the origin checkpoint block had been pruned from the database, causing the node to crash.
Forkchoice Stability: An important fix ensures that the safe/finalized hash computation correctly handles reorged payloads, preventing a state where the node could get stuck and fail to propose blocks.
Monitoring Fix: Corrected the reporting of head, source, and target attestations when using the --monitor-indices flag.

Other Improvements

New --disable-log-colors flag: This new flag for the beacon chain and validator client allows users to suppress ANSI color codes in log output, which is helpful when redirecting logs to a file or a log aggregation service.
Experimental State Diffs: The experimental --enable-state-diff feature now supports reconstructing caches from the database on restart, enabling a node to successfully resume from an hdiff database. This feature is not yet recommended for production.

Release Notes

## [v7.1.4](https://github.com/prysmaticlabs/prysm/compare/v7.1.3...v7.1.4) - 2026-05-22

This is a maintenance release with significant progress on the Gloas implementation alongside important production fixes and performance improvements. There are no known security issues in this release. Operators may update at their convenience.

Release highlights:

- **Gloas fork progress**: PTC (payload timeliness committee) duties, payload attestation pool and gossip, proposer preferences, execution payload bid processing, builder voluntary exit handling, data column sidecar validation, observability metrics, and block proposing with P2P bids are all wired up in preparation for upcoming devnet testing.
- **Memory optimization**: Validator state representation compacted from ~264 to ~128 bytes per validator, saving ~300–450 MB of heap on mainnet (~2.2M validators). This also reduces GC pressure.
- **Sync committee duties fix**: Eliminated expensive state replays when computing sync committee members for the current period, which previously caused periodic CPU spikes ([#16686](https://github.com/OffchainLabs/prysm/issues/16686)).
- **Missed attestation fix**: Newly-activated validators no longer miss their first attestation when using `--enable-beacon-rest-api` ([#16723](https://github.com/OffchainLabs/prysm/issues/16723)).
- **Monitor indices fix**: Corrected head, source, and target reporting when using the `--monitor-indices` flag ([#16801](https://github.com/OffchainLabs/prysm/issues/16801)).
- **Crash fix**: Resolved a nil panic in `fetchOriginSidecars` when the origin checkpoint block has been pruned from the DB ([#16824](https://github.com/OffchainLabs/prysm/issues/16824)).
- **State diffs (experimental)**: `--enable-state-diff` now supports reconstructing caches from DB via hdiff nodes. This feature is experimental and not yet recommended for production use.
