@swc/core, a super-fast alternative to Babel, released version 1.2.2 shortly after 1.2.1, both on June 14th, 2020. While seemingly minor, the updates are valuable for developers seeking optimal performance in their JavaScript and TypeScript compilation workflows. The dependency and devDependency listings remain identical between the two versions, including crucial tools like typescript, @babel/core, jest, and browserslist, ensuring consistent behavior and compatibility for projects already leveraging these technologies. Both versions depend on the same versions of core tools like mkdirp, progress, node-fetch, and true-case-path.
The key difference lies in the dist section. Version 1.2.2 exhibits a slightly larger unpacked size of 3,512,082 bytes compared to 1.2.1's 3,511,717 bytes, a modest increase of a few hundred bytes reflecting internal improvements or bug fixes. The fileCount remains constant at 455. The very short time span ( around 8 hours ) coupled with minor size difference suggests 1.2.2 contains primarily bug fixes, potentialy related to packaging. Users are advised to upgrade as any patch release typically contains improvements for stability from the previous version, though without specific changelog details, the precise nature of these fixes remains opaque. Both versions emphasize swc's commitment to performance and developer-friendly tooling.
