  * Type Checker: Interface functions must be declared external. This was already the case in the experimental 0.5.0 mode.
  * Type Checker: Address members are not included in contract types anymore. An explicit conversion is now required before invoking an ``address`` member from a contract.
  * Type Checker: Disallow "loose assembly" syntax entirely. This means that jump labels, jumps and non-functional instructions cannot be used anymore.
- * Remove obsolete ``std`` directory from the Solidity repository. This means accessing ``https://github.com/ethereum/solidity/blob/develop/std/*.sol`` (or ``https://github.com/ethereum/solidity/std/*.sol`` in Remix) will not be possible.
+ * Type System: Disallow explicit and implicit conversions from decimal literals to ``bytesXX`` types.
+ * Type System: Disallow explicit and implicit conversions from hex literals to ``bytesXX`` types of different size.
+ * Remove obsolete ``std`` directory from the Solidity repository. This means accessing ``https://github.com/ethereum/soldity/blob/develop/std/*.sol`` (or ``https://github.com/ethereum/solidity/std/*.sol`` in Remix) will not be possible.
  * References Resolver: Turn missing storage locations into an error. This was already the case in the experimental 0.5.0 mode.
  * Syntax Checker: Disallow functions without implementation to use modifiers. This was already the case in the experimental 0.5.0 mode.
  * Syntax Checker: Named return values in function types are an error.
