Version Details and Security Vulnerabilities

React-lifecycles-compat is a valuable utility for React developers, providing a seamless bridge for class components to maintain compatibility across different React versions. Versions 3.0.3 and 3.0.4 both offer this backwards compatibility polyfill, targeting developers who want to ensure their React components function predictably, especially when dealing with evolving lifecycle methods. Examining the differences between these versions reveals a subtle refinement rather than a major overhaul.

Both versions share the same core development dependencies, including tools like camelcase, chalk, eslint, jest, prettier, and rollup, indicating a consistent approach to code quality, testing, and build processes. Both versions are released under the MIT license, and they point to the same repository.

The primary distinction lies in the dist metadata. Version 3.0.4, released on May 11, 2018, has a slightly larger unpacked size of 29017 bytes compared to version 3.0.3's 28536 bytes, released on May 9, 2018. Both versions contain the same number of files (8). This increase in size suggests minor adjustments or improvements within the compiled code, possibly addressing edge cases or optimizing performance. While the change is not drastic, developers aiming for the most up-to-date and potentially refined version of the polyfill should opt for 3.0.4. The release date difference of two days suggests a quick follow-up release for a minor bug fix or enhancement, making 3.0.4 the preferred choice for projects where compatibility and predictable behavior are paramount.
