EIP-7685 Requests: EIP-6110 (Deposits) / EIP-7002 (Withdrawals) / EIP-7251 (Consolidations)

This library now supports EIP-6110 deposit requests, see PR #3390, EIP-7002 withdrawal requests, see PR #3385 and EIP-7251 consolidation requests, see PR #3477 as well as the underlying generic execution layer request logic introduced with EIP-7685 (PR #3372).

These new request types will be activated with the Prague hardfork, see @ethereumjs/block README for detailed documentation.

EIP-2935 Serve Historical Block Hashes from State (Prague)

Starting with this release the VM supports EIP-2935 which stores the latest 256 block hashes in the storage of a system contract, see PR #3475 as the major integrational PR (while work on this has already been done in previous PRs).

This EIP will be activated along the Prague hardfork. Note that this EIP has no effect on the resolution of the BLOCKHASH opcode, which will be a separate activation taking place by the integration of EIP-7709 in the following Osaka hardfork.

Verkle Dependency Decoupling

We have relatively light-heartedly added a new @ethereumjs/verkle main dependency to the VM/EVM stack in the v7.2.1 release, which added an additional burden to the bundle size by several hundred KB and additionally draws in unnecessary WASM code. Coupling with Verkle has been refactored in PR #3462 and the direct dependency has been removed again.

An update to this release is therefore strongly recommended even if other fixes or features are not that relevant for you right now.
