Express 3.0 是一个维护版本，针对 2.x 版修复了很多问题，并加入了很多新功能。
在使用 Express 框架时，要记住，Express 框架是帮助开发者快速实现 HTTP 通信相关的功能，而不是成为像 Rails 那样功能强大、全面的框架。
Connect 2.x
Changes introduced by Connect 2.x:
err.status support to Connect’s default end-point session() “proxy” setting to trust “X-Forwarded-Proto” okieSession() middleware compress(are for gzipped responses multipart() middleware json() middleware urlencoded() middleware limit option to the three above middleware fer option to multipart() to listen on formidable’s events added debug() instrumentation to aid in debugging basicAuth()’s req.remoteUser to req.user session() to only set-cookie on modification (hashed session json) changed bodyParser() to be an aggregate of json(), multipart() and urlencoded() many cookie-related utils into npm moved static()’s logic into a separate npm module named “send” increase perf ~%20 by memoizing url parsing removed router() middleware default encoding for logger(), now “utf8” instead of “ascii” fixed mount-path case-sensitivity
