Summary
This medium-priority release contains bugfixes for issues identified in v5.2.0. Users who have experienced sync issues with v5.2.0 are recommended to upgrade.
The list of bugfixes includes:
- Prevention of forwards sync stalls after restarting, through more robust handling of peer disconnects and errors (#5969, #5945, #5993).
- Prevention of backfill sync stalls (#5969).
- Removal of unnecessary warnings for stale blobs propagated on gossip by other clients (#5935). The log message
WARN Could not verify blob sidecar for gossip. Ignoring the blob sidecar
should no longer be seen. - Correct sizing of the slasher database for the growing validator sets on mainnet and Holesky (#5934).
Breaking Changes
There are no breaking changes between v5.2.0 and v5.2.1. Please see the release notes for v5.2.0 if you are upgrading from a prior 5.x.x release.
Known Issues
Nethermind v1.26.0 and Reth v1.0.0 engine_getClientVersionV1
bug
Nethermind v1.26.0 and Reth v1.0.0 include an implementation of engine_getClientVersionV1
which is not compliant with the API specification and does not work with Lighthouse. We recommend upgrading Nethermind to v1.27.0. At time of writing there is no compatible Reth release available.
The warning generated by a non-compliant implementation is:
WARN Execution engine call failed error: InvalidClientVersion("Input must be exactly 8 characters long (excluding any '0x' prefix)"), service: exec
This warning can be safely ignored, although it may cause a slight degradation to node performance as Lighthouse flip-flops the EL's state between healthy and unhealthy.
See NethermindEth/nethermind#7013 and paradigmxyz/reth#9137 for details.
Source builds without jemalloc
will OOM on Linux
We've become aware of OOM issues for Lighthouse builds from source that disable the jemalloc
feature on Linux. This is due to GNU malloc not handling the allocation of many tree nodes as well as other allocators (jemalloc, the Windows allocator). If you are building from source for Linux ensure that you include jemalloc
in FEATURES
(enabled by default). If you build the Dockerfile
use --build-arg FEATURES=jemalloc
(not enabled by default).
This will be addressed in v5.3.0 by an already-merged PR: #5995
Update Priority
This table provides priorities for which classes of users should update particular components.
User Class | Beacon Node | Validator Client |
---|---|---|
Staking Users | Medium | Low |
Non-Staking Users | Medium | --- |
See Update Priorities for more information about this table.
Lighthouse BNs and VCs from v5.0.0, v5.1.x and v5.2.x are compatible. However, we recommend that users update both the VC and BN to v5.2.1 if upgrading.
