This release fixes a bug in the routine that copies dynamically-sized arrays to storage. More details about the bug can be found in the blog post.

Important Bugfixes

  • Code Generator: Properly cleanup after copying dynamic-array to storage for packed types.

Compiler Features

  • Code generator: Implemented events with function type as one of its indexed parameters.
  • General: Option to stop compilation after parsing stage. Can be used with solc --stop-after parsing
  • Optimizer: Optimize exp when base is -1.
  • SMTChecker: Support addmod and mulmod.
  • SMTChecker: Support array slices.
  • SMTChecker: Support type conversions.

Bugfixes

  • Fixed internal compiler errors for certain contracts involving the new expression.
  • JSON AST: Fix internal error when using --ast-json on a function with memory arguments in ABIEncoderV2 contracts.
  • Type Checker: Add missing checks for calls using types incompatible with ABIEncoderV1 in modules where ABIEncoderV2 is not enabled.
  • Type Checker: Fix internal compiler error when calling .push(<arg>) for a storage array with a nested mapping.

We especially thank all the contributors that made this release possible:
