Solidity 0.4.13 Release Announcement

Posted by Solidity Team on July 6, 2017


This is a small bugfix release that fixes several trivial but very annoying bugs that were introduced with 0.4.12. We also deprecate some old features in preparation of the breaking release 0.5.0.


  • Syntax Checker: Deprecated throw in favour of require(), assert() and revert().
  • Type Checker: Warn if a local storage reference variable does not explicitly use the keyword storage.


  • Code Generator: Correctly unregister modifier variables.
  • Compiler Interface: Only output AST if analysis was successful.
  • Error Output: Do not omit the error type.

A big thank you to all contributors who helped make this release possible!
