 Compiler Features:
- * Support ``petersburg`` as ``evmVersion``.
+ * Support ``petersburg`` as ``evmVersion`` and set as default.
  * Inline Assembly: Consider ``extcodehash`` as part of Constantinople.
  * Inline Assembly: Instructions unavailable to the currently configured EVM are errors now.
  * SMTChecker: Do not report underflow/overflow if they always revert. This removes false positives when using ``SafeMath``.

    - Opcodes ``returndatacopy``, ``returndatasize`` and ``staticcall`` are available in assembly.
    - The ``staticcall`` opcode is used when calling non-library view or pure functions, which prevents the functions from modifying state at the EVM level, i.e., even applies when you use invalid type conversions.
    - It is possible to access dynamic data returned from function calls.
