mev-geth v0.4

Changes

• 🧮 Add support for Megabundles
• 🐛 Fix double-counting bug for gas in profit switcher.

What are Megabundles?

Megabundles are a feature of mev-geth which allows trusted relayers to submit larger, pre-merged and ordered bundles of transactions to miners. These bundles are scored and sorted against the normal bundle merging code already in mev-geth, and allows for relays to improve bundle scoring without impacting the performance of mev-geth for all miners.

Check out the specification, the rpc interface, and the release notes.
