 Important Bugfixes:
  * ABI Decoder V2: For two-dimensional arrays and specially crafted data in memory, the result of ``abi.decode`` can depend on data elsewhere in memory. Calldata decoding is not affected.

  * Commandline Interface: Model checker option ``--model-checker-targets`` also accepts ``outOfBounds``.
  * Commandline Interface: New model checker option ``--model-checker-contracts`` allows users to select which contracts should be analyzed as the most derived.
  * Low-Level Inliner: Inline ordinary jumps to small blocks and jumps to small blocks that terminate.
+ * NatSpec: Allow ``@notice`` tag on non-public state variables and local variable declarations. The documentation will only be part of the AST, under the field ``documentation``.
  * SMTChecker: Deprecate ``pragma experimental SMTChecker;`` and set default model checker engine to ``none``.
  * SMTChecker: Report local variables in CHC counterexamples.
  * SMTChecker: Report out of bounds index access for arrays and fixed bytes.

- * Yul Optimizer: Added a new step FunctionSpecializer, that specializes a function with its literal arguments.
  * Yul EVM Code Transform: Stack Optimization: Reuse slots of unused function arguments and defer allocating stack slots for return variables until after expression statements and assignments that do not reference them.

 Bugfixes:
- * Natspec: Fix internal error related to the `@returns` documentation for a public state variable overriding a function.
  * Antlr Grammar: Fix parsing of import paths involving properly distinguishing between empty and non-empty string literals in general.
  * AST Output: Fix ``kind`` field of ``ModifierInvocation`` for base constructor calls.
+ * Commandline interface: Fix internal error when printing AST and using ``--base-path`` or ``file://`` prefix in imports.
  * Commandline interface: Fix standard input bypassing allowed path checks.
+ * Natspec: Fix internal error related to the `@returns` documentation for a public state variable overriding a function.
  * SMTChecker: Fix false positive and false negative on ``push`` as LHS of a compound assignment.
  * SMTChecker: Fix false positive in contracts that cannot be deployed.
  * SMTChecker: Fix internal error on public getter returning dynamic data on older EVM versions where these are not available.
  * SMTChecker: Fix internal error on try-catch with function call in catch block.
  * Type Checker: Fix missing error when events are used without an emit statement.
- * Commandline interface: Fix internal error when printing AST and using ``--base-path`` or ``file://`` prefix in imports.
 
 
 AST Changes:
- * New property for ContractDefinition nodes: ``usedErrors`` lists AST IDs of all errors used by the contract (even if defined outside).
