Connect 3.0

For sure

• Remove multipart middleware. Use one of the following parsers or middleware instead:
  • formidable
  • connect-multiparty or multiparty
  • connect-busboy or busboy
• Remove staticCache. Use one of the following alternatives (feel free to add more):
  • st
  • express-static-cache
• Remove limit middleware. No longer used by any of the parsers.

Maybe

• Remove node 0.8 support
  • Remove pause utility
  • Remove any unnecessary patches in https://github.com/senchalabs/connect/blob/master/lib/patch.js
