Browserify, a tool enabling require() in browsers for JavaScript directories and npm modules, saw a minor version update from 1.7.5 to 1.7.6 in late October 2011. Examining the manifests, the core functionality, expressed through the description, remains consistent: Browserify continues to provide server-side module compatibility to client-side JavaScript. The dependencies, listing essential packages like nub, resolve, optimist, commondir, detective, and coffee-script, are identical between the two versions, indicating no fundamental changes to the underlying module resolution or core processing mechanisms. Similarly, devDependencies, including testing and development utilities such as seq, tap, jade, dnode, jsdom, connect, hashish, backbone, traverse, and jquery-browserify, are unchanged. This suggests that the internal testing and development workflows remained stable during this update.
Crucially, the only apparent difference lies in the version number and consequently the releaseDate and the dist.tarball URL, which points to the specific tarball for each version on the npm registry. Version 1.7.6 was released on October 29, 2011, a couple of days after 1.7.5 which was released on October 27, 2011. For developers, upgrading from 1.7.5 to 1.7.6 likely involves minimal risk, as the dependency tree and functionality appear to be preserved. While the changelog would provide further details, the manifest difference suggests a patch or minor update, potentially addressing bug fixes or small performance improvements without introducing breaking changes. Developers should still consult the official changelog for complete details on the specific adjustments between these versions before upgrading in production applications.
