Semver, the semantic version parser vital for npm package management, saw a minor version bump from 4.0.2 to 4.0.3 in late September/early October 2014. Examining the metadata reveals subtle differences, primarily revolving around the release date. Version 4.0.2 was released on September 30th, 2014, at 23:55:26.916Z, while 4.0.3 followed closely on October 1st, 2014, at 00:18:37.208Z.
Both versions share identical descriptions, development dependencies (tap 0.x >=0.0.4 and uglify-js ~2.3.6), BSD license, and Git repository details. This suggests that the core functionality and dependencies remained consistent between the two releases. Developers relying on semver for version parsing within their npm workflows can infer that the update from 4.0.2 to 4.0.3 likely involved minimal changes. Judging by the proximity of the release dates any change probably regards very minor bug fixes or purely metadata changes not affecting regular use. While specifics aren't detailed in the data provided, the consistency in other fields indicates that the update was likely a low-risk proposition for developers already using semver 4.0.2. Developers should always evaluate changelogs.
