## [0.24.0] — unreleased

This release brings the state gas repricing to the Amsterdam EVM revision
and consolidates the test tools into a single `evmone test` command.

### Added

- **Amsterdam EVM revision**: next set of EIPs.
- [EIP-8037]: State Creation Gas Cost Increase — a second gas dimension
metering the state growth, funded by a per-frame state gas reservoir.
[#1672](https://github.com/ipsilon/evmone/pull/1672)
- [EIP-8038]: State-access gas cost update.
[#1731](https://github.com/ipsilon/evmone/pull/1731)
[#1732](https://github.com/ipsilon/evmone/pull/1732)
- **The `evmone test` command** runs both state and blockchain test fixtures,
recognizing the format of each fixture. It prints a pytest-like report
and supports the `--ignore` and `--collect-only` options.
[#1683](https://github.com/ipsilon/evmone/pull/1683)
[#1684](https://github.com/ipsilon/evmone/pull/1684)
[#1685](https://github.com/ipsilon/evmone/pull/1685)
[#1687](https://github.com/ipsilon/evmone/pull/1687)
[#1699](https://github.com/ipsilon/evmone/pull/1699)
[#1716](https://github.com/ipsilon/evmone/pull/1716)
- The `--trace-summary` of `evmone test` reports the logs hash,
and the new `--state-diff` option adds the transaction state diff to it.
[#1722](https://github.com/ipsilon/evmone/pull/1722)
[#1723](https://github.com/ipsilon/evmone/pull/1723)

### Changed

- **EVMC ABI version bumped to 19**: `evmc_message::state_gas` and
`evmc_result::state_gas` carry the [EIP-8037] state gas reservoir.
[#1672](https://github.com/ipsilon/evmone/pull/1672)
- The call depth limit is not checked from Osaka on: the [EIP-7825] transaction
gas limit together with the 63/64 call gas rule keeps the depth below 500.
[#1704](https://github.com/ipsilon/evmone/pull/1704)
- **`modexp` optimizations**: the Montgomery multiplication carries are folded
into a single addition (halving the 256-bit `modexp` time with GCC on x86-64)
and the exponent is reduced for the power-of-two part of the modulus
(up to ~30% faster for even moduli with wide exponents).
[#1662](https://github.com/ipsilon/evmone/pull/1662)
[#1708](https://github.com/ipsilon/evmone/pull/1708)
- **BN254 pairing (`ecpairing`) optimizations**: a single Miller loop
accumulator shares the Fq12 squarings across all pairs.
[#1544](https://github.com/ipsilon/evmone/pull/1544)
[#1637](https://github.com/ipsilon/evmone/pull/1637)
[#1646](https://github.com/ipsilon/evmone/pull/1646)
- The EVMMAX modular arithmetic moved into the `evmone::crypto` namespace
of the precompiles library; the `evmone::evmmax` target and
the `include/evmmax/evmmax.hpp` header are gone.
[#1652](https://github.com/ipsilon/evmone/pull/1652)
[#1657](https://github.com/ipsilon/evmone/pull/1657)
[#1659](https://github.com/ipsilon/evmone/pull/1659)
- The state-independent CALL costs are charged before the [EIP-7702]
delegation lookup, as in [execution-specs].
[#1668](https://github.com/ipsilon/evmone/pull/1668)
- **CMake 3.25** is the minimum required version.
[#1660](https://github.com/ipsilon/evmone/pull/1660)
- Dependencies upgraded: libsecp256k1 v0.8.0, blst v0.3.17, googletest v1.18.0.
google/benchmark is fetched with FetchContent instead of Hunter.

[#1656](https://github.com/ipsilon/evmone/pull/1656)
[#1661](https://github.com/ipsilon/evmone/pull/1661)
- The [Execution Spec Tests] fixtures upgraded to `tests@v21.0.0`

and `tests-glamsterdam-devnet@v8.1.4`.
[#1682](https://github.com/ipsilon/evmone/pull/1682)
[#1734](https://github.com/ipsilon/evmone/pull/1734)

### Removed

- The `evmone-statetest` and `evmone-blockchaintest` tools,
replaced by `evmone test`. The `--gtest_*` options are gone with them.
[#1685](https://github.com/ipsilon/evmone/pull/1685)

### Fixed

- The blob fee in the transaction affordability check could overflow,
letting a transaction with a huge `max_fee_per_blob_gas` pass the balance check.
[#1714](https://github.com/ipsilon/evmone/pull/1714)
- A reverted cold access to a non-existent account restored it as an existing
empty account, which showed up as a spurious deleted account in the state diff.
[#1709](https://github.com/ipsilon/evmone/pull/1709)
- `evmone t8n` emitted receipts with a hard-coded success status and no logs,
and reported the post-refund block `gasUsed` in Amsterdam ([EIP-7778]).
[#1667](https://github.com/ipsilon/evmone/pull/1667)
[#1698](https://github.com/ipsilon/evmone/pull/1698)
- A subcommand name among another subcommand's arguments (e.g. a trailing `run`)
was silently executed instead of the requested command.
[#1691](https://github.com/ipsilon/evmone/pull/1691)
- A blockchain test which failed early skipped all the following tests
in the same fixture file.
[#1690](https://github.com/ipsilon/evmone/pull/1690)
