Thunder's Goat

v1.3.0-rc.4 -- Thunder's Goat -- is the fourth release candidate for the coming Capella upgrade.

This release ushers in many new test generators for kzg-4844 libraries (#3274). Huge shout-out to @dankrad for driving this.

Beyond that, this includes a number of minor patches and iterative changes to Deneb in continued refinement for upcoming devnets.

This release does not change Capella consensus logic.
