Version 0.12.5

Added

• Header is now an iterator which is an alias to encoded_multi_items.
  Instead of reparsing the headers for every middleware, keep the instance and mimic a fitting generator.- sniff method on Request.

Changed

• receive, send are not properties anymore on Request but proper methods. receive has a replay mode for sniff.

Fixed

• StaticFiles without scope headers failed.
• StaticFiles were susceptible for path traversal attacks.
• Calling Request.headers could empty the headers in scope when just a generator.
• Messages were not replayed in case ContinueRouting was raised. This prevented sniffing like documented.
