This version of EVMC delivers compatibility with Istanbul EVM revision. The ABI breaking change has been required in this case so some other backward-incompatible changes are also included and deprecated APIs have been removed.

Added

  • Support for Istanbul EIP-1344 (CHAINID opcode). chain_id added to evmc_tx_context struct. #375
  • Support for Istanbul EIP-1884 (Repricing for trie-size-dependent opcodes). #372
  • The Berlin EVM revision number has been added. #407
  • In C++ API, an overload for VM::execute() has been added that omits the Host context and interface parameters. This is useful for Precompiles VMs that do not interact with the Host. #302

Changed

  • The evmc_instance renamed to evmc_vm. #430
  • The evmc_context renamed to evmc_host_context. #426
  • The evmc_host_interface is now separated from evmc_host_context. This simplifies language bindings which implement the evmc_host_interface. #427
  • The evmc::vm renamed to evmc::VM in C++ API. #252
  • Previously deprecated helpers.hpp header file has been removed. #410
  • Previously deprecated EVMC_CONSTANTINOPLE2 and EVMC_LATEST_REVISION revisions have been removed. #411
  • Previously deprecated tracing API has been removed. #429
  • In evmc::instructions library the undefined instructions have 0 gas cost instead of previous -1 value.
    #425
  • The EVM instruction tables have been redesigned to be more useful. #435
  • The EVMC loader trims all extensions (previously only the last one) from the EVMC module file name. #439
  • The EVMC loader no longer ties to guess the VM create function name by dropping prefix words from the name. #440
  • The helper function evmc_is_abi_compatible() returns now bool instead of int. #442
  • In the Rust bindings make ExecutionContext optional within execute. #350
  • A set of small improvements to C++ API. #445 #449 #451
