Browserify is a powerful tool that lets developers use Node.js-style require() statements in the browser, allowing for modular JavaScript development and the reuse of npm packages in client-side applications. Version 0.4.2, released on May 24, 2011, builds upon the foundation of version 0.4.1, released just a few days earlier on May 18, 2011. Both versions share a core set of dependencies including findit, source, hashish, es5-shim, and coffee-script, essential for file system navigation, source code manipulation, and compatibility.
The key difference lies in the development dependencies. Version 0.4.2 introduces jade and expresso to the devDependencies, specifically jade at version =0.10.4 and expresso at version =0.7.x. This suggests an enhanced focus on templating and testing capabilities within the Browserify development workflow possibly making contributions to Browserify easier. Both versions include seq, dnode, connect, backbone, and traverse as development tools. Developers upgrading from 0.4.1 to 0.4.2 might experience subtle improvements in build processes or testing frameworks due to the addition of jade and expresso. If you contribute to Browserify, version 0.4.2 is recommended to take advantage of a newer test environment. For simple usage of the library, the changes may be negligible.
