Recent updates

  • v5.0.0-alpha.3

    v5.0.0-alpha.3 primarily updates the project to be compatible only with newer versions of typescript-eslint. The release notes document a breaking removal of typescript-eslint v5 support, and the diff shows dependency upgrades to the typescript-eslint v8 line.

    Breaking

  • v5.0.0-alpha.2

    Release v5.0.0-alpha.2 contains a single change: it bumps the dependency eslint-visitor-keys from v3 to v4. Release notes describe this as a bug fix related to dependency updates.

  • v5.0.0-alpha.1

    v5.0.0-alpha.1 formally bumps the minimum supported Node.js and ESLint versions. The diff itself shows changes only to CI/workflows and package metadata/dev tooling, not any runtime source code.

    Breaking

  • v4.9.1

    v4.9.1 is documented as a bug fix release focused on ESLint v9 compatibility. The code diff shows additional robustness changes in several AST helper utilities, mainly adding null checks around `node.parent` to prevent crashes and adjust return values in edge cases.

  • v4.9.0

    v4.9.0 adds support for the latest typescript-eslint behavior in the isParenthesized logic. The release notes only mention this single feature and provide no further details.

    Features

  • v4.8.0

    v4.8.0 ships a bug fix in get-static-value to avoid returning a static value when a variable is mutated after initialization. It also extends isParenthesized to correctly handle TypeScript AST constructs, specifically around generic type parameters in CallExpression and NewExpression.

    Features

  • v4.7.0

    v4.7.0 adds TypeScript AST support for `getStaticValue` and `ReferenceTracker`, enabling evaluation and reference tracking of common TypeScript expression forms. It also includes a fix related to the `preversion` npm script, but the diff shows additional build/test script and CI changes beyond what is mentioned in the release notes.

    Features

  • v4.6.1

    v4.6.1 is a small patch release focused on improving compatibility with Node 12. The documented change is limited to a Node 12 fix, with no new features called out.

  • v4.6.0

    v4.6.0 adds generation of TypeScript declaration files (.d.ts) from the project’s JSDoc types, alongside validation of those type comments. The release notes only mention this feature, but the diff also includes a broader build and tooling change (new TS-based declaration build pipeline) and multiple internal code adjustments.

    Features

  • v4.5.1

    Release v4.5.1 contains a bug fix for a crash in `getStringIfConstant` when evaluating `Symbol.prototype`. The implementation now guards `String(evaluated.value)` with a try/catch and ensures a null return when static evaluation is not usable.
