v1.8.0

Featured Changes

• feat/perf: use native assertions by @klkvr in #514.
  • This replaces forge-std Solidity code with native cheatcode assertions from Foundry, so should give a small performance boost.
  • Assertion failures now cause tests to exit early, instead of continuing with execution.
  • This also will require some visibility modifier changes to tests, as assertion methods no longer set state.
  • NOTE: If you were using the vm.expectSafeMemory cheat, you may need to now use the new vm.stopExpectSafeMemory cheat from #507. See #503 (comment) to learn more, h/t @clabby.
• feat(stdStorage): support packed variables by @klkvr in #505. This means deal now works with USDC and other variables that reply on packed storage slots.
  • The USDC deal support works out of the box.
  • To avoid breaking changes arbitrary packed slot support is not enabled by default, and can be enabled with stdstore.enable_packed_slots().target(.....
• feat: add TOML reading/writing cheatcodes by @zerosnacks in #518. These are analogous to their JSON equivalents.
  • NOTE: This adds file specific keyExistsJson and keyExistsToml cheats. The ambiguous keyExists currently is an alias for keyExistsJson and will be deprecated.
• feat: native string maniupulation cheatcodes of toLowercase, toUppercase, trim, replace and split from foundry-rs/foundry#6891.
• feat: implement interfaces in mock tokens by @arr00 in #510.

Other Changes

• Exclude internal cheats from Vm by @klkvr in #501.
• Fix typo in StdJson.sol usage comments by @coopbri in #511.
• feat: fraxtal mainnet/testnet rpc support by @pegahcarter in #517.

New Contributors

• @coopbri made their first contribution in #511.
• @arr00 made their first contribution in #510.
• @pegahcarter made their first contribution in #517.
• @zerosnacks made their first contribution in #518.

Full Changelog: v1.7.6...v1.8.0

v1.7.6

Featured Changes:

• New cheatcodes:
  • vm.dumpState by @tynes in #499 (foundry-rs/foundry#6827)
  • vm.signP256 cheatcode for generating P256 (i.e. secp256r1) signatures, by @wilsoncusack in #497 (foundry-rs/foundry#6797)
  • vm.toBase64 and vm.toBase64URL cheatcodes by @ 0xAndoroid and @DaniPopes in #499 (foundry-rs/foundry#6785 and foundry-rs/foundry#6830)

Other Changes

• fix: don't hardcode string values in Vm generator by @DaniPopes in #497
• chore: bump to v1.7.6 by @mds1 in #500

Full Changelog: v1.7.5...v1.7.6

v1.7.5

Featured Changes

• vm.envOr and vm.getLabel are now view @anikaraghu in #491

Other Changes

• feat: automatically generate Vm.sol from cheatcodes.json by @DaniPopes in #487
• chore: bump to v1.7.5 by @mds1 in #492

New Contributors

• @anikaraghu made their first contribution in #491

Full Changelog: v1.7.4...v1.7.5

v1.7.4

Featured Changes

• Update Vm.sol with changes to AccountAccessKind by @emo-eth in #483.
  • This adds Balance, Extcodesize, Extcodehash, Extcodecopy as account access kinds
• feat: add new snapshot cheatcodes by @mattsse in #484.
  • The vm.revertTo(snapshotId) cheat does not automatically delete the snapshotId snapshot, which can lead to unbounded memory growth with lots of snapshots. Therefore, vm.revertToAndDelete(snapshotId), vm.deleteSnapshot(snapshotId), and vm.deleteSnapshots() were added as new cheats.

Other Changes

• chore: bump to v1.7.4 by @mds1 in #486

Full Changelog: v1.7.3...v1.7.4

v1.7.3

Featured Changes

• feat: add vm.startStateDiffRecording and vm.stopAndReturnStateDiff cheats to record all account accesses and storage accesses, by @Inphi in #481
• feat: add vm.computeCreateAddress and vm.computeCreate2Address cheats, by @qiweiii in #479
  • These native cheats replace the need for the StdUtils methods of the same now, which will now give a deprecation warning when used.
• feat: add mock contracts for ERC20 and ERC721, by @andreivladbrg in #470
  • Be aware that these use initializers instead of constructors for compatibility across Solidity versions. Therefore it's recommended to use the deployMockERC20 and deployMockERC721 methods in StdUtils to deploy them.

Other Changes

• chore: bump version to v1.7.3 by @mds1 in #482

New Contributors

• @Inphi made their first contribution in #481
• @qiweiii made their first contribution in #479
• @andreivladbrg made their first contribution in #470

Full Changelog: v1.7.2...v1.7.3

v1.7.2

Featured Changes

• feat: add vm.loadAllocs(string) cheatcode by @tynes in #474. This reads in a JSON file to directly set state for many accounts at once.
• feat: add vm.eth_getLogs and vm.rpc cheats by @Evalir in #475. The vm.eth_getLogs cheat makes an eth_getLogs RPC call and returns the result, and the vm.rpc cheat allows arbitrary RPC calls to be made. These query the current fork URL.

Other Changes

• fix: rely less on foundry internals by @DaniPopes in #473
• fix: test naming by @totomanov in #472
• chore: bump to v1.7.2 by @mds1 in #478

New Contributors

• @totomanov made their first contribution in #472
• @tynes made their first contribution in #474

v1.7.0

Featured Changes

• chore(BREAKING CHANGE): Change exit_code to exitCode by @PaulRBerg in #458
  • This is a breaking change for any users who use the exit_code variable in the FfiResult struct¹
• feat: add new vm.serializeJson cheatcode to the Vm and to StdJson by @vdrg in #453
• feat: add vm.unixTime to VmSafe interface by @Tudmotu in #465
• perf: mark vm.parseJsonKeys as pure by @PaulRBerg in #460

Other Changes

• chore: reorder Vm for logical consistency by @mds1 in #464

Full Changelog: v1.6.1...v1.7.0

1. exit_code was recently introduced, and a sourcegraph search did not reveal many existing users of it. Because this repo uses camelCase, it was determined this breaking change was acceptable to keep things consistent, even though this technically does not follow semver. ↩
