Version Details and Security Vulnerabilities

@swc/core version 1.3.102 is a refined iteration of the super-fast Babel alternative, building upon the foundations laid by version 1.3.101 and preceding releases. Both versions share the same core dependencies, including @swc/types and @swc/counter, and an extensive suite of devDependencies catering to tasks like testing, linting, and code formatting. Primarily, the update introduces enhancements behind the scenes, contributing to improved performance and stability.

Developers leveraging SWC for speedy JavaScript and TypeScript compilation will find the transition between 1.3.101 and 1.3.102 seamless. The API remains largely consistent, ensuring minimal disruption to existing workflows. Examining the optionalDependencies, which include platform-specific binaries (darwin, linux, win32 across various architectures), reveals that both versions provide architecture-specific packages for optimized performance, indicating an ongoing focus on delivering the best possible experience across diverse environments.

Significant changes probably lie in the binaries of the core package "@swc/core-*" delivering better performance. While the development dependencies remain identical, the updated release may incorporate crucial bug fixes and internal optimizations. The releaseDate fields indicate that 1.3.102 was released more recently, suggesting it includes the latest improvements and refinements made to the compiler. The unpacked size is different between the 2 versions, indicating internal code changes.
