v0.20.2

This version fixes a problem where fallback() {} functions had a visibility of external instead of indicating that there was no explicit visibility.

v0.20.0

This version adds support for custom storage layout.

v0.19.0

This version adds support for transient storage variables.

v0.18.0

This version adds 2 new features.

• Parser function now has an option to return comments as part of the parsed result. (#105)
• We now export umd instead of iife format for browser compatibility. (#106)

v0.17.0

This version changes the associativity of the exponentiation and ternary operators. In most cases this shouldn't affect anyone, but it's technically a breaking change.

• Using the official typescript target for antlr4. (#103)
• Exponentiation is now right associative. a ** (b ** c) (#99)
• Conditional expression is now right associative. a ? (b ? c : d) : (e ? f : g) (#99)

v0.16.2

This version adds support for top-level event definitions, a feature introduced in solc v0.8.22.

v0.16.1

This version fixes a bug where variables named global couldn't be parsed (thanks @arjun-io!)

v0.16.0

This version adds support for user-defined operators.

The UsingForDeclaration node now has a new operators property. This is an array with the same length as the functions array. Each item is either a string or null: if an operator is defined, then the string is the operator; if an operator is not defined, the item is null.

For example, using { add as +, sub } for Fixed18 global will result in this node:

{
  "type": "UsingForDeclaration",
  "isGlobal": true,
  "typeName": {
    "type": "UserDefinedTypeName",
    "namePath": "Fixed18"
  },
  "libraryName": null,
  "functions": ["add", "sub"],
  "operators": ["+", null]
}

v0.15.0

This release adds support for named parameters in mapping types, introduced in solc 0.8.18.

v0.14.5

This release:

• Fixes assembly assignment to multiple variables (thanks @potomak!)
• Adds support for boolean literals in assembly (thanks @tim-becker!)
