## [0.22.0] — unreleased

Comment thread
chfast marked this conversation as resolved.
This release starts the implementation of the Amsterdam EVM revision.

### Added

- **Amsterdam EVM revision** with the implementation of the initial set of EIPs.
[#1508](https://github.com/ipsilon/evmone/pull/1508)
- [EIP-7778]: Block Gas Accounting without Refunds.
[#1526](https://github.com/ipsilon/evmone/pull/1526)
- [EIP-7843]: SLOTNUM opcode.
[#1517](https://github.com/ipsilon/evmone/pull/1517)
- [EIP-7976]: Increase Calldata Floor Cost.
[#1519](https://github.com/ipsilon/evmone/pull/1519)
- [EIP-7981]: Increase Access List Cost.
[#1524](https://github.com/ipsilon/evmone/pull/1524)
- [EIP-8024]: Backward compatible SWAPN, DUPN, EXCHANGE.
[#1429](https://github.com/ipsilon/evmone/pull/1429)

### Changed

- **EVMC ABI version bumped to 13**: the `evmc_tx_context` layout changed
(the SLOTNUM addition and the removals listed below) along with other
incompatible EVMC API changes.
[#1567](https://github.com/ipsilon/evmone/pull/1567)
- **BN254 pairing (`ecpairing`) optimizations**: line evaluation optimized,
dedicated `Fq2` squaring, points migrated to affine/projective representations.
[#1539](https://github.com/ipsilon/evmone/pull/1539)
[#1541](https://github.com/ipsilon/evmone/pull/1541)
[#1542](https://github.com/ipsilon/evmone/pull/1542)
[#1545](https://github.com/ipsilon/evmone/pull/1545)
[#1546](https://github.com/ipsilon/evmone/pull/1546)
[#1547](https://github.com/ipsilon/evmone/pull/1547)
- **KZG point evaluation precompile optimizations**: joint G1 multi-scalar multiplication,
precomputed Miller-loop lines for the trusted setup point and the G2 generator.
[#1536](https://github.com/ipsilon/evmone/pull/1536)
[#1537](https://github.com/ipsilon/evmone/pull/1537)
[#1549](https://github.com/ipsilon/evmone/pull/1549)
- The t8n tool has been folded into the `evmone` CLI as the `t8n` subcommand.
[#1531](https://github.com/ipsilon/evmone/pull/1531)
[#1533](https://github.com/ipsilon/evmone/pull/1533)
[#1535](https://github.com/ipsilon/evmone/pull/1535)
[#1551](https://github.com/ipsilon/evmone/pull/1551)
- Blockchain test runner now matches expected block- and transaction-level exceptions.
[#1556](https://github.com/ipsilon/evmone/pull/1556)
[#1560](https://github.com/ipsilon/evmone/pull/1560)
[#1561](https://github.com/ipsilon/evmone/pull/1561)
- Upgraded [blst] to 0.3.16.
[#1534](https://github.com/ipsilon/evmone/pull/1534)
- `modexp` 256-bit Almost Montgomery Multiplication keeps its accumulator in
registers by avoiding output/input aliasing (~6% faster on 256-bit benchmarks).
[#1477](https://github.com/ipsilon/evmone/pull/1477)

### Removed

- Standalone `evmone-t8n` tool — use the `evmone t8n` subcommand instead.
[#1551](https://github.com/ipsilon/evmone/pull/1551)
- EOF leftovers dropped from the EVMC API: the `EOFCREATE` call kind
and the `initcodes` transaction context.
[#1514](https://github.com/ipsilon/evmone/pull/1514)
[#1515](https://github.com/ipsilon/evmone/pull/1515)
- The `evmc_result` optional storage.
[#1529](https://github.com/ipsilon/evmone/pull/1529)

### Fixed

- The instruction counting tracer (`--opcode.count`) kept a dangling reference
to the output path.
[#1554](https://github.com/ipsilon/evmone/pull/1554)
