Browserify 1.11.1 is a minor patch release following version 1.11.0, both designed to bring Node.js-style modules to the browser. Developers using Browserify can write modular JavaScript code using require() statements, making large-scale web applications more maintainable and organized. Both versions share the same core functionality and description: enabling browser-side require() for JavaScript directories and npm modules. Key dependencies such as resolve, coffee-script, vm-browserify, http-browserify, and crypto-browserify remain consistent, ensuring access to features like module resolution, CoffeeScript support, and browser-compatible implementations of core Node.js modules.
The main difference lies in the dependency specifications for nub, deputy, optimist, commondir and detective. Version 1.11.1 introduces slightly stricter or more well-defined version constraints for some of these dependencies, for example nub goes from 0.0.x to ~0.0.0 and optimist goes from ~0.2.6 to ~0.3.4, potentially addressing compatibility issues or incorporating minor updates from those packages. The devDependencies, including testing tools like seq and tap, and libraries for development environments like jade, lazy, dnode, connect, hashish, backbone, ecstatic, traverse, jquery-browserify, remain the same, suggesting no significant changes to the development workflow or testing environment. This patch release likely focuses on stabilizing the existing feature set rather than introducing new capabilities. The release dates also show a very short time window, which reinforces the idea of a patch change.
