Version 1.3.45 of @swc/core represents a minor update to the super-fast Babel alternative, building upon the foundation laid by version 1.3.44. The core functionality, a high-performance JavaScript and TypeScript compiler, remains consistent, but the changes primarily involve dependency updates and potential bug fixes that enhance stability and performance.
Crucially, all platform-specific dependencies within @swc/core, such as @swc/core-darwin-x64, @swc/core-linux-x64-gnu, and others, have been bumped from version 1.3.44 to 1.3.45. This synchronized update across architectures suggests improvements or fixes that impact the core compilation process consistently across different operating systems and CPU architectures. Also, @swc/plugin-jest was updated from 1.5.25 to 1.5.56.
Developers adopting @swc/core for its speed in transforming modern JavaScript and TypeScript will benefit from this incremental improvement. While the core API likely remains unchanged, the underlying engine has been refined. Existing users are encouraged to upgrade to 1.3.45 to take advantage of these enhanced architecture-specific improvements, potentially experiencing slight performance gains or resolution of minor bugs. New adopters can be confident that they are starting with a more polished and stable version of this popular compiler. The slight increase in unpacked size indicates small additions or modifications to the underlying compiled code. Considering the relatively short release cadence it is safe to assume that upgrading will result in minimal backward compatiblity issues.
