### 0.6.0 (unreleased)
Breaking changes:
* ABI: remove the deprecated ``constant`` and ``payable`` fields.
* ABI: the ``type`` field is now required and no longer specified to default to ``function``.
* C API (``libsolc``): the provided callback now takes two parameters, kind and data. The callback can then be used for multiple purposes, such has file imports and SMT queries.
* C API (``libsolc``): Introduce context parameter.
* Commandline interface: remove the text-based ast printer (``--ast``).
* Command line interface: Switch to the new error reporter by default. ``--old-reporter`` falls back to the deprecated old error reporter.
* Command line interface: Add option to disable or choose hash method between IPFS and Swarm for the bytecode metadata.
* ABI: Remove the deprecated ``constant`` and ``payable`` fields.
* ABI: The ``type`` field is now required and no longer specified to default to ``function``.
* AST: Inline assembly is exported as structured JSON instead of plain string.
* C API (``libsolc``): Introduce context parameter to both ``solidity_compile`` and the callback.
* C API (``libsolc``): The provided callback now takes two parameters, kind and data. The callback can then be used for multiple purposes, such has file imports and SMT queries.
* Commandline Interface: Remove the text-based AST printer (``--ast``).
* Commandline Interface: Switch to the new error reporter by default. ``--old-reporter`` falls back to the deprecated old error reporter.
* Commandline Interface: Add option to disable or choose hash method between IPFS and Swarm for the bytecode metadata.
* General: Disallow explicit conversions from external function types to ``address`` and add a member called ``address`` to them as replacement.
* General: Enable Yul optimizer as part of standard optimization.
* General: New reserved keywords: ``virtual``.
* General: New reserved keywords: ``override``, ``receive``, and ``virtual``.
* General: ``private`` cannot be used together with ``virtual``.
* General: Split unnamed fallback functions into two cases defined using ``fallback()`` and ``receive()``.
* Inheritance: State variable shadowing is now disallowed.
* Inline Assembly: Only strict inline assembly is allowed.
* Inline Assembly: Variable declarations cannot shadow declarations outside the assembly block.
* JSON AST: Replace ``superFunction`` attribute by ``baseFunctions``.
* Natspec JSON Interface: Properly support multiple ``@return`` statements in ``@dev`` documentation and enforce named return parameters to be mentioned documentation.
* Source mappings: Add "modifier depth" as a fifth field in the source mappings.
* Standard JSON Interface: Add option to disable or choose hash method between IPFS and Swarm for the bytecode metadata.
* Syntax: ``push(element)`` for dynamic storage arrays do not return the new length anymore.
* Syntax: Abstract contracts need to be marked explicitly as abstract by using the ``abstract`` keyword.
* Inline Assembly: Only strict inline assembly is allowed.
* Inline Assembly: Variable declarations cannot shadow declarations outside the assembly block.
* Syntax: ``length`` member of arrays is now always read-only, even for storage arrays.
* Type checker: Resulting type of exponentiation is equal to the type of the base. Also allow signed types for the base.

Language Features:
* Allow global enums and structs.
* Allow underscores as delimiters in hex strings.
* Allow explicit conversions from ``address`` to ``address payable`` via ``payable(...)``.
* Allow global enums and structs.
* Allow public variables to override external functions.
* Allow underscores as delimiters in hex strings.
* Introduce syntax for array slices and implement them for dynamic calldata arrays.
* Introduce ``push()`` for dynamic storage arrays. It returns a reference to the newly allocated element, if applicable.
* Introduce ``virtual`` and ``override`` keywords.
* Modify ``push(element)`` for dynamic storage arrays such that it does not return the new length anymore.
* Yul: Introduce ``leave`` statement that exits the current function.
* Allow public variables to override external functions.
Compiler Features:
* Allow revert strings to be stripped from the binary using the ``--revert-strings`` option or the ``settings.debug.revertStrings`` setting.

Compiler Features:
* Commandline Interface: Allow translation from yul / strict assembly to EWasm using ``solc --yul --yul-dialect evm --machine eWasm``
* Commandline Interface: Allow translation from yul / strict assembly to EWasm using ``solc --yul --yul-dialect evm --machine ewasm``
* Set the default EVM version to "Istanbul".
* SMTChecker: Add support to constructors including constructor inheritance.
* Yul: When compiling via Yul, string literals from the Solidity code are kept as string literals if every character is safely printable.
