 ### 0.8.0 (unreleased)
 
 Breaking Changes:
+ * Assembler: The artificial ASSIGNIMMUTABLE opcode and the corresponding builtin in the "EVM with object access" dialect of Yul take the base offset of the code to modify as additional argument.
  * Type System: Unary negation can only be used on signed integers, not on unsigned integers.
  * Type System: Disallow explicit conversions from negative literals and literals larger than ``type(uint160).max`` to ``address`` type.
  * Parser: Exponentiation is right associative. ``a**b**c`` is parsed as ``a**(b**c)``.
