Express 3.0是一個維護版本，針對2.x版修複了很多問題，并加入了很多新功能。

在使用Express架構時，要記住，Express架構是幫助開發者快速實作HTTP通信相關的功能，而不是成為像Rails那樣功能強大、全面的架構。

Connect 2.x

Changes introduced by Connect 2.x:

added err.status support to Connect’s default end-point

added session() “proxy” setting to trust “X-Forwarded-Proto”

added cookieSession() middleware

added compress() middleware for gzipped responses

added multipart() middleware

added json() middleware

added urlencoded() middleware

added limit option to the three above middleware

added defer option to multipart() to listen on formidable’s events

added debug() instrumentation to aid in debugging

changed basicAuth()’s req.remoteUser to req.user

changed session() to only set-cookie on modification (hashed session json)

changed bodyParser() to be an aggregate of json(), multipart() and urlencoded()

moved 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

fixed default encoding for logger(), now “utf8” instead of “ascii”

fixed mount-path case-sensitivity

Connect docs are available at http://www.senchalabs.org/connect/, and will eventually be mirrored on expressjs.com as well for convenience, along with usage guides.
