@swc/core, a super-fast alternative to Babel, saw a minor version bump from 1.2.20 to 1.2.21. Both versions share the same core dependencies like mkdirp, progress, node-fetch, and true-case-path, and the same development dependencies including testing frameworks like jest, utility libraries like lodash, and Babel-related tools such as @babel/core, @babel/preset-env, and various Babel plugins. The typescript version also remains the same at 3.9.7. The key distinction between the two versions lies in the dist section of the package metadata. Version 1.2.21 includes 458 files in its distribution, whereas version 1.2.20 contained 454 files. The unpacked size of version 1.2.21 is also larger, at 3493794 bytes compared to 3435663 bytes for the previous version. This suggests that version 1.2.21 introduced new features, bug fixes, or performance improvements that required additional code or resources, potentially affecting build times or bundle sizes for developers. Finally, their release dates differ, with version 1.2.21 released on August 24, 2020, and version 1.2.20 released on August 15, 2020. Developers should review the changelog or release notes for @swc/core to understand the specific changes introduced in version 1.2.21 and assess their impact on their projects.
