Full Changelog: seth/0.11.0...hevm/0.49.0

Added

• seth basefee command returns basefee for the latest block, or any block with [blocknumber] parameter
• seth namehash <name> to get the ENS namehash of a name
• seth resolve-name <name> to resolve an ENS name to an address
• seth lookup-address <address> to lookup the ENS name an address reverse resolves to
• Dynamic transaction fee format transactions (EIP-1559) supported by introducing the flag --prio-fee and corresponding environment variable ETH_PRIO_FEE to seth and ethsign. If --prio-fee is provided (or ETH_PRIO_FEE) is set, 1559 transaction will be used and --gas-price will reflect the maximum gas price, rather than the absolute gas price.
• If ETH_RPC_ACCOUNTS is set and the account corresponding to ETH_FROM exists in the keystore,
  Seth will sign the transaction locally and then publish it signed (previously it'd always send it to the node)

Changed

• --gas-price will be used as max-fee when --prio-fee is set
• [BREAKING] seth will no longer search Parity / OpenEthereum related keystores by default. These
  keystores can still be searched by setting the ETH_KEYSTORE environment variable.

Fixed

• Fix --use bug
• seth bundle-source writes the contents of standard-json to the current directory to enable better sourcemaps for multi-file etherscan source code.
• seth estimate no longer sets a gas limit when estimating gas

Added

• Support for 0.8.4 custom error types in stack traces
• Colored coverage output

Changed

• Contract feching happens synchronously again.
• Invariants checked before calling methods from targetContracts.

Fixed

• The block gas limit and basefee are now correctly fetched when running tests via rpc

Changed

• Makes --keystore argument to ethsign import no longer mandatory, defaulting to
  systems paths or to the value of the ETH_KEYSTORE environment variable.
• ethsign import --keystore was changed to ethsign import --key-store for consistency
  with other commands.
• [BREAKING] removes Parity / OpenEthereum related default keystores

Added

• DAPP_TEST_DEPTH env var to control --depth
• --coverage flag for dapp test to generate coverage via hevm
• dapp debug respects the DAPP_LINK_TEST_LIBRARIES environment variable.
• dapp install accepts URLs with git tags, branches or revs specified as <url>@<tag>

Changed

• Dapp debug respects DAPP_LINK_TEST_LIBRARIES

Fixed

• Fix quotation bug in dapp replay

Changed

• Updated to London hard fork!
• The configuration variable DAPP_TEST_BALANCE_CREATE has been renamed to DAPP_TEST_BALANCE
• Default smttimeout has been increased to 1 minute.
• A new flag has been added to hevm (--ask-smt-iterations) that controls the number of iterations
  at which the symbolic execution engine will stop eager evaluation and begin to query the smt
  solver whether a given branch is reachable or not.
• Contract fetching now happens asynchronously.
• Fixed no contract definition crashes
• Removed NoSuchContract failures

Added

• A new test runner for checking invariants against random reachable contract states.
• hevm symbolic can search for solc 0.8 style assertion violations, and a new --assertions flag
  has been added allowing users to customize which assertions should be reported
• A new cheatcode ffi(string[]) that executes an arbitrary command in the system shell

Changed

• Z3 is once again the default smt solver
• Updated nixpkgs to the 21.05 channel

Fixed

• Sourcemaps for contracts containing immutable are now shown in the debug view.

Added

• A new type of test has been added: invariant testing, which runs a test function against a random
  reachable contract state. More information in the README
• A new flag for dapp test, --ffi allows users to enable the ffi() cheatcode in their tests

Changed

• solc 0.8.6 is now the default compiler version
• updated nixpkgs to the 21.05 channel

Added

• Updated to Berlin! Conformant with GeneralStateTests at commit hash 644967e345bbc6642fab613e1b1737abbe131f78.

Fixed

• ADDMOD and MULMOD by zero yields zero.
• Address calculation for newly created contracts.
• Accomodated for the notorious "anomolies on the main network" (see yellow paper Appendix K for trivia)
• A hevm crash when debugging a SELFDESTRUCT contract.
