Buffer <-> Uint8Array Conversion Helpers (RLP v3)
The new RLP v3 release is accepting and returning
Uint8Arrayobjects instead ofBufferfor improved browser compatibility and usage.There are two new helper functions in the
bytesmodule from theUtillibrary introduced in PR #1648 to help with associated Buffer conversions (while this is our main reason for introducing these functions the functionality can of course be used for other things as well):arrToBufArr(): Converts aUint8ArrayorNestedUint8ArraytoBufferorNestedBufferArraybufArrToArr(): Converts aBufferorNestedBufferArraytoUint8ArrayorNestedUint8ArrayNote: the RLP version exposed by this package as a re-export is still RLP
v2. This won't change along additionalv7Util releases and other current monorepo libraries (VM, Tx,...) are also still using thev2RLP version.Features

Removal of ethjs-util Package Re-Export
This release replaces
ethjs-utildependency with aninternal.tsfile which re-exports all the used functions (thanks to @talentlessguy for the PR).This has a list of benefits:

New EVM/VM Profiler
This releases ships with a completely new dedicated EVM/VM profiler (❤️ to Jochem for the integration) to measure how the different opcode implementations are doing, see PR #2988, #3011, #3013 and #3041.
Most of profiling is taking place in the EVM (so: the dedicated opcode profiling), see the respective README section for usage instructions and the EVM v2.1.0 CHANGELOG for latest performance gains.
The VM adds to the profiler (see new
profileroption) by adding output within the tx or block scope alongrunTx()orrunBlock()runs (committing state, block rewards,...).The VM profiler addition now also allows for running blockchain or state tests with the profiler activated, e.g. to benchmark certain extreme-case or attack scenarios, see DEVELOPER docs for usage instructions (see PR #3115).
EIP-7516 BLOBBASEFEE Opcode
This release supports EIP-7516 with a new
BLOBBASEFEEopcode added to and scheduled for the Dencun HF, see PR #3035 and #3068. The opcode returns the value of the blob base-fee of the current block it is executing in.Dencun devnet-11 Compatibility
This release contains various fixes and spec updates related to the Dencun (Deneb/Cancun) HF and is now compatible with the specs as used in devnet-11 (October 2023).
