Release v1.44.0

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.

Release v1.43.0

Good day Lodestar operators! We've just released v1.43.0 and recommend users upgrade for the latest features and best performance. This release has an important fix or self rate-limiting so that we are better peers, and thus have better peering and syncing. We also fixed a bug in block-import performance, as well as another substantial wave of ePBS / Gloas progress.

Operational Note: Internal tooling moved to pnpm v11. There will be no action required for operators running via Docker, however if you are building from source you will need to update your version of pnpm.

Release v1.42.0

Hey Lodestar operators! We've just released v1.42.0 and recommend users upgrade for the latest features and best performance.

QUIC transport is now enabled by default. As noted in the v1.41.0 release, this change was coming. If you haven't already, you must allow UDP traffic on port 9001 through your firewall. Without this, your node will have degraded connectivity. If you need to disable QUIC for any reason, you can use --quic=false or --no-quic. Check out our networking docs for more details.

This release also includes a fix for QUIC early adopters from last release. Lodestar now only creates QUIC clients for address families that are actually configured, so QUIC works out of the box regardless of your network setup.

We are making great strides towards the Gloas hard-fork with this release but have added a couple of small things that will make operation user experience more cozy. In particular, the voluntary exit command can now write to file instead of publishing directly for those of you with complex setups.
