    2 months ago

    v3.0.0-rc.1 is a major release that updates tooling and dependency versions, and it also establishes a new supported versions baseline (TypeScript 5.5.2+, Node 20.19.0+). The code diff shows substantial changes to the published package format (ESM-only) and removal of multiple deprecated exports and type guards.

  • v2.5.0

    2 months ago

    Release v2.5.0 focuses on tooling and dependency updates, with a documented change to `isStrictCompilerOptionEnabled` defaulting to `strict: true` behavior for TypeScript 6. However, the code diff shows additional runtime changes and multiple new public exports (including comment and token iterators) plus a naming migration from `*TypeParts` to `*Constituents` that are not reflected in the provided release notes.
