Version 1.3.94 of @swc/core, released on October 21, 2023, is a minor update to the super-fast Babel alternative, building upon the previous stable version, 1.3.93, released on October 13, 2023. Both versions share the core functionality of providing a speedy transpilation solution for JavaScript and TypeScript, designed to improve build times and developer productivity. They maintain identical dependencies for core operations and development tooling, including @swc/types and @swc/counter for core functionality, and Jest, TypeScript, and Babel-related tools for testing and development.
The key difference lies within the optional dependencies and internal distribution. Version 1.3.94 updates its optional platform-specific binaries like @swc/core-darwin-x64 and @swc/core-linux-x64-gnu to version 1.3.94, ensuring compatibility and potential performance improvements or bug fixes specific to those platforms. These optional dependencies provide optimized builds for different operating systems and architectures, contributing to the overall performance and stability of the package across diverse environments. While the unpacked size of v1.3.94 (222451 bytes) is slightly smaller than v1.3.93 (228555 bytes) likely due to internal optimizations. For developers, this minor version bump signifies a focus on platform-specific enhancements and stability, encouraging an upgrade for those seeking the latest refinements in SWC's performance on their target platforms.
