Version Details and Security Vulnerabilities

Type-Fest version 4.0.0 introduces a notable update to this essential TypeScript utility library compared to version 3.13.1. Both versions maintain the core purpose of providing a rich collection of type definitions to enhance TypeScript development. A key difference lies in the upgraded xo dependency, moving from version 0.54.2 to 0.55.0. While seemingly minor, this upgrade likely brings refinements in code linting rules and potentially contributes to code quality improvements within Type-Fest itself. Developers who rely on xo in their own projects might appreciate this alignment if they are using relatively recent versions of the linter. The unpacked size of version 4.0.0 is marginally larger (273971 bytes) compared to version 3.13.1 (273907 bytes), hinting at potential additions or modifications to type definitions, although the file count remains the same at 107. The release timestamps are very close, with only a 16 minute difference between version 4 and version 3. Being a major version release, 4.0.0 may also include breaking changes or significant enhancements in certain types. Developers should review the changelog for specifics before upgrading. Type-Fest continues to be dual-licensed under MIT or CC0-1.0, ensuring broad compatibility with various project types. Main author being Sindre Sorhus is a guarantee of quality and support. All the rest of the dependencies and characteristics seems to remain untouched.
