Version Details and Security Vulnerabilities

Babel-runtime versions 5.2.15 and 5.2.14 represent incremental updates to Babel's self-contained runtime library, designed to provide polyfills and helper functions necessary for running compiled JavaScript code in various environments, particularly those lacking modern JavaScript features. Both versions share the same core functionality, description, author (Sebastian McKenzie), repository, and declare a dependency on core-js version ^0.9.0, indicating a reliance on the core-js library for providing polyfills for features like promises and iterators.

The primary difference between the two versions lies in their release dates, with version 5.2.15 being published approximately 28 minutes later than version 5.2.14 on May 5th, 2015. This suggests that 5.2.15 likely includes minor bug fixes or very small improvements over 5.2.14. However, without specific release notes or a detailed changelog, it's difficult to pinpoint the exact changes.

For developers using Babel, the babel-runtime package is crucial for ensuring compatibility across different browsers and JavaScript environments. When utilizing the "transform-runtime" Babel plugin, this package is automatically included in your project, providing necessary support for features like async/await, generators, and other ES2015+ constructs. While the difference between versions 5.2.14 and 5.2.15 might be negligible, keeping your dependencies up-to-date is generally recommended for benefiting from the latest fixes and potential performance improvements. Consider consulting the broader Babel changelog or repository history for more detailed information on the specific changes introduced in version 5.2.15 if a precise understanding is required.
