@@ -7,18 +7,19 @@ Language Features:
 Compiler Features:
  * SMTChecker: Create balance check verification target for CHC engine.
  * Yul IR Code Generation: Cheaper code for reverting with errors of a small static encoding size.
+ * Yul Optimizer: New, faster default optimizer step sequence.
 
 
 Bugfixes:
  * Commandline Interface: Fix ICE when the optimizer is disabled and an empty/blank string is used for ``--yul-optimizations`` sequence.
- * Optimizer: Fix optimizer executing each repeating part of the step sequence at least twice, even if the code size already became stable after the first iteration.
  * SMTChecker: Fix false positive when comparing hashes of same array or string literals.
  * SMTChecker: Fix internal error on mapping access caused by too strong requirements on sort compatibility of the index and mapping domain.
  * SMTChecker: Fix internal error when using an empty tuple in a conditional operator.
  * SMTChecker: Fix internal error when using bitwise operators with an array element as argument.
  * Standard JSON Interface: Fix ICE when the optimizer is disabled and an empty/blank string is used for ``optimizerSteps`` sequence.
  * StaticAnalyzer: Only raise a compile time error for division and modulo by zero when it's between literals.
  * TypeChecker: Fix compiler crash when the left-hand side of an assignment was a parenthesized non-tuple expression of a tuple type.
+ * Yul Optimizer: Fix optimizer executing each repeating part of the step sequence at least twice, even if the code size already became stable after the first iteration.
  * Yul Optimizer: Fix the order of assignments generated by ``SSATransform`` being dependent on AST IDs, sometimes resulting in different (but equivalent) bytecode when unrelated files were added to the compilation pipeline.
