Browserify is a powerful tool that allows developers to use Node.js-style require() statements in browser-side JavaScript code, enabling modularity and code reuse. Versions 1.1.0 and 1.1.1 of Browserify share a common core, both designed to bundle JavaScript directories and npm modules for use in web browsers. They list the same dependencies: "resolve", "detective", and "coffee-script", ensuring consistent module resolution and code analysis capabilities. Similarly, their development dependencies, including tools like "seq", "jade", "dnode", and "jsdom," are identical, indicating a stable development and testing environment across both versions.
However, version 1.1.1, released on June 21, 2011, at 23:30:34 UTC, represents a subtle update compared to version 1.1.0, released earlier that same day at 11:06:25 UTC. While the core functionality and dependencies remain unchanged, the release of 1.1.1 suggests a bug fix or minor enhancement implemented within that ~12-hour window. For developers, this implies that upgrading to 1.1.1 is likely a safe and recommended practice, ensuring they benefit from the latest stability improvements. Since the changelog is not provided, the nature of the change remains unknown, but upgrading to the latest version is generally considered a best practice to avoid potential known bugs in version 1.1.0. Both versions maintain the same MIT/X11 license and are authored by James Halliday, pointing to continuous improvements.

}
return result;
}
u.parse("var a = " + genstr(process.argv[2], "1") + ".1ee7;");
