Core-js is a widely used JavaScript standard library offering polyfills for the latest ECMAScript features, ensuring compatibility across diverse JavaScript environments. Version 3.4.1 builds upon the solid foundation of 3.4.0, presenting subtle yet impactful refinements for developers.
Both versions share the same core MIT license and are managed through the same GitHub repository, signaling consistent project governance. A significant funding model via Open Collective remains in place. The jump from version 3.4.0 to 3.4.1 represents a minor version update, typically focused on bug fixes and incremental improvements without introducing breaking changes or major new features.
An intriguing detail is the slight increase in fileCount from 1678 to 1679 and unpackedSize from 628800 to 628890. This indicates that version 3.4.1 includes a small amount of additional code, possibly addressing specific edge cases, clarifying documentation, or optimizing existing polyfills. Developers will appreciate that such increments usually translate to better overall stability and refinement in edge case scenarios.
The release dates provide context: version 3.4.0 was released on November 6, 2019, while 3.4.1 followed shortly after on November 12, 2019. This proximity suggests that 3.4.1 might address a bug fix or a specific issue uncovered in 3.4.0 shortly after its release. For those using core-js it's advisable to use the latest version to benefit from these refinements.
