Version Details and Security Vulnerabilities

Es6-set offers a polyfill for the ECMAScript6 Set data structure, enabling developers to use the Set object in environments that don't natively support it. Comparing versions 0.1.5 and 0.1.4, several dependency updates stand out. Version 0.1.5 upgrades d from "~0.1.1" to "1", es5-ext from "~0.10.11" to "~0.10.14", es6-iterator from "2" to "~2.0.1", es6-symbol from "3" to "3.1.1" and event-emitter from "~0.3.4" to "~0.3.5". These updates potentially bring performance improvements, bug fixes, and new features from the respective dependencies. While not explicitly stated, these dependency bumps likely address underlying compatibility issues or security vulnerabilities that have been resolved in the newer versions of the sub-modules.

Developers should carefully evaluate these dependency changes when upgrading. While seemingly minor, a shift from major version 2 to "~2.0.1" for es6-iterator or event-emitter reflects a more specific version targeting potentially mitigating unintended breaking changes introduced in intermediary releases. The upgrade of es6-symbol to 3.1.1 is also considerable. Also the upgrade of the dependency d from "~0.1.1" to "1" it's pretty important. The upgrade of es5-ext could be important since it's a pretty common module for es5 extensions. The move to newer versions generally indicates a more robust and feature-rich polyfill, staying current with the evolving JavaScript landscape.
