ethereum/solidity v0.4.11

Version 0.4.11

on GitHub

This release fixes a bug in the optimizer (more about this on the blog), introduces the standard JSON interface, adds interface contracts and implements some additional safety checks.

The standard JSON interface provides a unified way to invoke the Solidity compiler in order to ease cross-platform adoption and compilation verification.

Features:

• Implement the Standard JSON Input / Output API
• Support interface contracts.
• C API (jsonCompiler): Add the compileStandard() method to process a Standard JSON I/O.
• Commandline interface: Add the --standard-json parameter to process a Standard JSON I/O.
• Commandline interface: Support --allow-paths to define trusted import paths. Note: the
  path(s) of the supplied source file(s) is always trusted.
• Inline Assembly: Storage variable access using _slot and _offset suffixes.
• Inline Assembly: Disallow blocks with unbalanced stack.
• Static analyzer: Warn about statements without effects.
• Static analyzer: Warn about unused local variables, parameters, and return parameters.
• Syntax checker: issue deprecation warning for unary '+'

Bugfixes:

• Assembly output: Implement missing AssemblyItem types.
• Compiler interface: Fix a bug where source indexes could be inconsistent between Solidity compiled
  with different compilers (clang vs. gcc) or compiler settings. The bug was visible in AST
  and source mappings.
• Gas Estimator: Reflect the most recent fee schedule.
• Type system: Contract inheriting from base with unimplemented constructor should be abstract.
• Optimizer: Number representation bug in the constant optimizer fixed.
