 * `"account_keys_path"`: `String` - Specifies a file to save accounts and private keys to, for testing.
 * `"vmErrorsOnRPCResponse"`: `boolean` - Whether or not to transmit transaction failures as RPC errors. Set to `false` for error reporting behaviour which is compatible with other clients such as geth and Parity. This is `true` by default to replicate the error reporting behavior of previous versions of ganache.
 * `"hdPath"`: The hierarchical deterministic path to use when generating accounts. Default: "m/44'/60'/0'/0/"
-* `"hardfork"`: Allows to specify which hardfork should be used. Supported hardforks are `byzantium` and `constantinople` (default)
+* `"hardfork"`: Allows to specify which hardfork should be used. Supported hardforks are `byzantium`, `constantinople`, and `petersburg` (default).
 * `"allowUnlimitedContractSize"`: `boolean` - Allows unlimited contract sizes while debugging. By setting this to `true`, the check within the EVM for contract size limit of 24KB (see [EIP-170](https://git.io/vxZkK)) is bypassed. Setting this to `true` **will** cause `ganache-core` to behave differently than production environments. (default: `false`; **ONLY** set to `true` during debugging).
 * `"gasPrice"`: Sets the default gas price for transactions if not otherwise specified. Must be specified as a hex string in wei. Defaults to `"0x77359400"`, or 2 gwei.
 * `"gasLimit"`: Sets the block gas limit. Must be specified as a hex string. Defaults to `"0x6691b7"`.
