Hey everyone! We're happy to release v1.32.0 to Lodestar users!

Firstly, we're happy to announce that all of our packages at Lodestar are now officially under Apache-2.0 licensing and the changes in our repository now reflect this.

Secondly, the release bumps our default gas limit signal to 45M as it was determined to be safe through testing during the protocol interop. You will not need to make any custom/flag changes to enable this.

If you've had any issues with block production, especially local block production, this upgrade is highly recommended as this release parallelizes some block building steps and optimizes our builder/engine race. It also includes additional optimizations to our proof verification.
