Release v1.14.0

Hey everyone! We've released v1.14.0 of Lodestar which is recommended for all users on all networks. This is the same version as v1.14.0-rc.2 which was the mandatory release for Goerli users for Deneb hard fork readiness.

• This release includes the scheduled Goerli test network fork for Deneb at epoch 231680.

• If using Lodestar for the Ephemery testnet, this version is compatible with the Deneb fork scheduled for iteration 111 on January 18, 2024.

• --blindedLocal is a new feature which allows local block publishing to be signed by the validator similarly to builder relays via blinded headers instead of having the full payload. For operators with their Lodestar beacon node and validator clients in separate hosts/networks, this feature will reduce block production latencies. This is only supported if it's a Lodestar beacon node using produceBlockV3.

• Breaking change for Deneb fork: The Deneb fork epoch will trigger the migration to use produceBlockV3 on Lodestar. If you do not want this, you MUST disable it with --produceBlockV3 false. Alternatively, if you want to turn it on for testing pre-Deneb, you can enable it with --produceBlockV3 true. The automatic switch to produceBlockV3 will only affect the Goerli network (the only scheduled network to fork on this release).

• Other block production optimizations to reduce block production latencies and likelihood of orphaning blocks due to reorgs.

• Lodestar now supports shouldOverrideBuilder functionality where execution clients can identify censorship and force local block production irrespective of the builderBoostFactor. See ethereum/execution-apis#425 for the specification and this note on the heuristics of how the execution client determines builder censorship: https://hackmd.io/@potuz/BkpzmOgK6.

• produceBlockV3 API now supports builder_boost_factor. Our documentation here (https://chainsafe.github.io/lodestar/validator-management/vc-configuration/#configure-your-builder-selection-andor-builder-boost-factor) includes details on how to use this with our already implemented --builder.selection feature.
