### 0.4.18 (unreleased)
Features:
* Code Generator: Always use all available gas for calls as experimental 0.5.0 feature
(previously, some amount was retained in order to work in pre-tangerine whistle
EVM versions)
* Parser: Better error message for unexpected trailing comma in parameter lists.
* Standard JSON: Support the ``outputSelection`` field for selective compilation of supplied sources.
* Syntax Checker: Unary ``+`` is now a syntax error as experimental 0.5.0 feature.
* Type Checker: Disallow non-pure constant state variables as experimental 0.5.0 feature.
* Code Generator: Always use all available gas for calls as experimental 0.5.0 feature
(previously, some amount was retained in order to work in pre-tangerine whistle
EVM versions)
* Type Checker: Do not add members of ``address`` to contracts as experimental 0.5.0 feature.
Bugfixes:
* Parser: Fix source location of VariableDeclarationStatement.
