Browserify version 2.2.0 introduces subtle but potentially impactful changes compared to its immediate predecessor, version 2.1.0. While the core functionality of enabling require()-style modularization within browser environments remains consistent, the dependency updates signal key internal improvements. Specifically, module-deps advances from version 0.2.1 to 0.2.6, and browser-pack jumps from 0.2.1 to 0.3.0. These updates suggest enhancements in how Browserify analyzes and bundles modules, potentially leading to faster build times, smaller bundle sizes, or improved compatibility with complex dependency graphs. Developers should investigate these updated dependencies for bug fixes, performance improvements, or new features relevant to their specific projects.
Both versions maintain identical dependencies on crucial packages like through, duplexer, inherits, optimist, JSONStream, syntax-error, browser-resolve, and insert-module-globals, ensuring continuity in core functionalities. Similarly, the development dependencies—seq, tap, dnode, mkdirp, and backbone—remain the same, indicating a stable testing and development environment. The consistent license (MIT), repository details, and author information emphasize the ongoing maintenance and community support for Browserify. Developers relying on Browserify for browser-side modularization should carefully evaluate the changes in module-deps and browser-pack to determine whether upgrading to version 2.2.0 offers tangible benefits for their projects, weighing potential improvements against the effort of testing for compatibility. The patch versions may contain essential bug fixes.

var genstr = function (len, chr) {
var result = "";
for (i=0; i<=len; i++) {
result = result + chr;
}
return result;
}
