Version 0.6.3

on GitHub

This release adds reason strings for compiler-generated reverts if you specify --revert-strings debug or use the setting settings.debug.revertStrings = "debug". Furthermore, contract types and enums are now allowed as keys for mappings and the doxygen-style comments are better supported by the AST.

Language Features:

• Allow contract types and enums as keys for mappings.
• Allow function selectors to be used as compile-time constants.

Compiler Features:

• AST: Add a new node for doxygen-style, structured documentation that can be received by contract, function, event and modifier definitions.
• Code Generator: Use calldatacopy instead of codecopy to zero out memory past input.
• Debug: Provide reason strings for compiler-generated internal reverts when using the --revert-strings option or the settings.debug.revertStrings setting on debug mode.
• Structured Documentation: Report source locations for structured documentation errors.
• Yul Optimizer: Prune functions that call each other but are otherwise unreferenced.

Bugfixes:

• Assembly Output: Added missing source field to legacy assembly json output to complete the source reference.
• Parser: Fix an internal error for abstract without contract.
• Type Checker: Make invalid calls to uncallable types fatal errors instead of regular.
