@@ -9,6 +9,7 @@ Compiler Features:
  * Commandline Interface: Add `--no-cbor-metadata` that skips CBOR metadata from getting appended at the end of the bytecode.
  * EVM: Deprecate ``block.difficulty`` and disallow ``difficulty()`` in inline assembly for EVM versions >= paris. The change is due to the renaming introduced by [EIP-4399](https://eips.ethereum.org/EIPS/eip-4399).
  * EVM: Introduce ``block.prevrandao`` in Solidity and ``prevrandao()`` in inline assembly for EVM versions >= paris.
+ * EVM: Set the default EVM version to "Paris".
  * EVM: Support for the EVM version "Paris".
  * Natspec: Add event Natspec inheritance for devdoc.
  * Standard JSON: Add a boolean field `settings.metadata.appendCBOR` that skips CBOR metadata from getting appended at the end of the bytecode.
