v5.0.2

This release has many optimizations, UX improvements, and bug fixes. Due to the number of important bug fixes and optimizations, we encourage all operators to update to v5.0.2 at their earliest convenience.

In this release, there is a notable change to the default value of --local-block-value-boost from 0 to 10. This means that the default behavior of using the builder API / mev-boost requires the builder bid to be 10% better than your local block profit. If you want to preserve the existing behavior, set --local-block-value-boost=0.
