Recent updates

  • v3.1.0

    Release v3.1.0 is described as a tiny performance improvement. The code change primarily optimizes how the RegExp tag is checked, with no apparent API changes.

  • v3.0.0

    v3.0.0 raises the minimum supported Node.js version and converts the package to ESM-only. The runtime implementation is essentially the same logic, but module entry and TypeScript typings changed accordingly.

    Breaking

  • v2.1.0

    Release v2.1.0 adds TypeScript type definitions to the package. No other functionality changes or fixes are mentioned in the release notes.
