### 0.4.22 (unreleased)
### 0.4.22 (2018-04-16)
Features:
* Code Generator: Initialize arrays without using ``msize()``.
* Code Generator: More specialized and thus optimized implementation for ``x.push(...)``
* Commandline interface: Error when missing or inaccessible file detected. Suppress it with the ``--ignore-missing`` flag.
* Constant Evaluator: Fix evaluation of single element tuples.
* General: Add encoding routines ``abi.encodePacked``, ``abi.encode``, ``abi.encodeWithSelector`` and ``abi.encodeWithSignature``.
* General: Add global function ``gasleft()`` and deprecate ``msg.gas``.
* General: Add global function ``blockhash(uint)`` and deprecate ``block.hash(uint)``.
* General: Allow providing reason string for ``revert()`` and ``require()``.
* General: Limit the number of errors output in a single run to 256.
* General: Support accessing dynamic return data in post-byzantium EVMs.
* General: Add encoding routines ``abi.encodePacked``, ``abi.encode``, ``abi.encodeWithSelector`` and ``abi.encodeWithSignature``.
* Inheritance: Error when using empty parentheses for base class constructors that require arguments as experimental 0.5.0 feature.
* Inheritance: Error when using no parentheses in modifier-style constructor calls as experimental 0.5.0 feature.
* Interfaces: Allow overriding external functions in interfaces with public in an implementing contract.
* Optimizer: Optimize ``SHL`` and ``SHR`` only involving constants (Constantinople only).
* Optimizer: Remove useless ``SWAP1`` instruction preceding a commutative instruction (such as ``ADD``, ``MUL``, etc).
@ -20,8 +24,7 @@ Features:
* Syntax Tests: Add source locations to syntax test expectations.
* Type Checker: Improve documentation and warnings for accessing contract members inherited from ``address``.
* General: Introduce new constructor syntax using the ``constructor`` keyword as experimental 0.5.0 feature.
* Inheritance: Error when using empty parentheses for base class constructors that require arguments as experimental 0.5.0 feature.
* Inheritance: Error when using no parentheses in modifier-style constructor calls as experimental 0.5.0 feature.
Bugfixes:
* Code Generator: Allow ``block.blockhash`` without being called.

* Parser: Fix internal compiler error when parsing ``var`` declaration without identifier.
* Parser: Fix parsing of getters for function type variables.
* Standard JSON: Support ``constantinople`` as ``evmVersion`` properly.
* Static Analyzer: Fix non-deterministic order of unused variable warnings.
* Static Analyzer: Invalid arithmetic with constant expressions causes errors.
* Type Checker: Fix detection of recursive structs.
* Type Checker: Fix asymmetry bug when comparing with literal numbers.
* Type System: Improve error message when attempting to shift by a fractional amount.
* Type System: Make external library functions accessible.
* Type System: Prevent encoding of weird types.
* Type System: Restrict rational numbers to 4096 bits.
* Static Analyzer: Fix non-deterministic order of unused variable warnings.
