We just published two fixes for socket.io-client:

• Building with browserify or webpack is now completely straightforward. No need to exclude/ignore or noParse/externals the ws module.

• Improved the JSONP transport when socket.io-client or engine.io-client are lazily evaluated or the <script> tag that included them gets removed.
