Hey there Lodestar operators!! We've just released v1.44.0 and recommend you upgrade for all testnet and mainnet nodes. This release continues our progress towards the Glamsterdam (ePBS) fork and there has been a lot of development in that direction. We also made some incremental performance improvements and updated our APIs. We have also added a new experimental feature, Fast Confirmation Rule. There are two major notes that we want to highlight for you.

FCR is a relatively new feature for Ethereum, and allows for confirming blocks much, much faster than is traditionally possible. However, there are a couple of small caveats that need to be pointed out. While the spec has been thoroughly tested, the feature is still new. We recommend rigor in testing before relying on it for any substantial economic security. It is pretty good at predicting the canonical chain correctly, but there are still some kinks that are being worked out. We have some performance updates that will follow in a future release. This will help make the guarantees even more secure.

FCR is a fairly performance intensive workload. We do not recommend running this feature on production nodes. As we, and other clients, further optimize for network conditions this stipulation might no longer apply, but for now we recommend experimenting with this on nodes without mainnet validators, as there may be effectiveness degradation.

Breaking Change: The deprecated v1 block-publishing and attestation-submission beacon API endpoints have been removed (#9531, #9532). Standard validator clients already use v2, but if you run custom tooling against these v1 endpoints, migrate to v2 before upgrading Lodestar.
