  * Type System: Explicit conversions from literals to integer type is as strict as implicit conversions.
  * Type System: Explicit conversions from literals to enums are only allowed if the value fits in the enum.
  * Type System: Declarations with the name ``this``, ``super`` and ``_`` are disallowed, with the exception of public functions and events.
+ * Command Line Interface: JSON fields `abi`, `devdoc`, `userdoc` and `storage-layout` are now sub-objects rather than strings.
 
 Language Features:
  * Super constructors can now be called using the member notation e.g. ``M.C(123)``.

+* Changed output of ``--combined-json``. JSON fields ``abi``, ``devdoc``, ``userdoc`` and ``storage-layout`` are sub-objects now. Before 0.8.0 they used to be serialised as strings.
