@chenrui333 To fix the startup failure add this flag to lighthouse bn:
--allow-insecure-genesis-sync
That is required when syncing from genesis now.

Any node which is not updated to a Lighthouse v5.x.x release by this time will stop following the chain and will need to be resynced. For stakers, this would result in missed rewards and penalties.
All Mainnet Lighthouse users must update their BNs and VCs to v5.0.0 by March 13, 2024, 01:55:35pm UTC.
This release also contains various bug-fixes, optimisations and new features:
--builder-proposals(#5151)distributedflag to VC to enable support for DVT (#4867)There are a few breaking changes. Please see the section on Breaking Changes below.
Mainnet Deneb/Cancun ("Dencun") Upgrade
The Deneb/Cancun ("Dencun") upgrade will occur on mainnet at:
All Lighthouse Beacon Nodes and Validator Clients must be upgraded to a v5.x.x release to ensure they follow the correct chain. The following table demonstrates which releases are reliable, Dencun-ready releases:
To be Dencun ready, user will need to:
There are no new flags to be added or removed for the Dencun upgrade, simply upgrade and wait.
Lighthouse will start periodically emitting the following logs two weeks before the Dencun upgrade (28th of February):
Not ready for Denebif Lighthouse has detected that the execution engine is too outdated to support Cancun.Ready for Denebif Lighthouse has detected a modern execution engine release.Just because Lighthouse is logging
Ready for Denebdoes not indicate that your execution engine is on the correct version. There is no way for Lighthouse to determine this exactly and users are responsible for ensuring that their execution engine is using the latest release.Note that with blobs (EIP-4844) being added in Dencun, each node is expected to consume additional disk space, with an expected average of 50 GiB, up to a maximum of 103GiB for blobs.
Fix bug in VC flag
--builder-proposals(#5151)There was a bug in the logic for the
--builder-proposalsVC flag introduced in Lighthouse v4.6.0. Rather than setting the boost to 0 whenbuilder-propsalswas false, it was setting it to 0 whenbuilder-proposalswas true. Users have been using--builder-boost-factor 100as a workaround until now.This issue has been resolved and the preference can now be enabled with the
--builder-proposals.See sigp/lighthouse#5151.
:warning: Breaking Changes :warning:
This release contains breaking changes, all of which are detailed below.
Validator Liveness endpoint now accepts string encoded indices
The standard liveness endpoint (
/eth/v1/validator/liveness) was introduced in the previous version of Lighthouse but did not accept string-encoded validator indices, which is part of the specification. This has been fixed and will require updating both BN and VC to the latest version.See sigp/lighthouse#5184.
Minimum Supported Rust Version 1.75.0
The minimum supported Rust version (MSRV) has been updated to 1.75.0. Users who compile from source (i.e., not Docker or pre-built binary users) will receive the following error if they are using an earlier version of Rust:
Users can typically obtain the latest version of Rust by running
rustup update.Deleted custom endpoint
lighthouse/beacon/states/{state_id}/sszThis endpoint is redundant and no longer required, because equivalent endpoints now exist in the standard beacon API.
See sigp/lighthouse#5065.
New mandatory
--checkpoint-blobsflag for manual checkpoint syncingFor users checkpoint syncing manually (previously using
--checkpoint-blockand--checkpoint-state), there is now an additional mandatory--checkpoint-blobsflag for users to supply the checkpoint blobs. Users using the--checkpoint-syncflag are not affected.See sigp/lighthouse#5252.
Deprecated BN flag
--disable-duplicate-warn-logsThis BN flag was introduced in Lighthouse v4.6.0. It has now become the default behaviour in this version, where gossipsub duplicate logs are
debuglevel instead ofwarn, thus deprecating this flag.See sigp/lighthouse#5163.
