Version Details and Security Vulnerabilities

Fastify-plugin version 2.0.0 represents a notable update to the utility designed to simplify Fastify plugin development. Comparing it to the previous stable version, 1.6.1, several key differences emerge. Firstly, a core dependency, semver, has been updated from ^6.3.0 to ^7.3.2, indicating enhanced handling of semantic versioning, potentially resolving compatibility issues or offering more robust version comparison capabilities. The development dependencies also reveal a shift. The update includes newer versions of development tools like tap (testing framework), fastify itself (aligned with more recent alpha release), typescript, and @types/node. The inclusion of tsd as a dev dependency is notable, suggesting a stronger emphasis on TypeScript definition testing.

Developers migrating to version 2.0.0 will likely benefit from improved compatibility with newer Fastify versions and an enriched TypeScript experience, ensuring more robust type checking. The expanded testing framework implied by upgraded tap and tsd versions should offer more confidence in the plugin's stability and reliability. While the core functionality might remain similar, the underlying improvements showcase a commitment to modernizing the library and aligning it with the evolving Fastify ecosystem. The change also includes an increase in unpacked size, suggesting slightly more code, types, and tests in latest version.
