v0.6.0

Major Changes

• The HTTP20Connection object is now thread-safe, so long as stream IDs are used on all method calls.
• Replaced the HTTP/2 state machine logic entirely to use hyper-h2. This will dramatically change the behaviour of the library in many situations, mostly for the better. However, this is also likely to introduce new bugs, so please be cautious.

API Changes

• Allow non-dictionary headers in request.
• HTTP20Connection now has a force_proto keyword argument to allow the HTTP20Connection to ignore the NPN/ALPN result.
• The --h2 CLI flag now ignores the result of NPN/ALPN negotiation when hitting HTTPS URLs.
• Added support for HTTPS client certificates.
• Notifications about streams being reset is now delayed to fire when the stream in question is next accessed, rather than immediately.

Bugfixes

• Overriding HTTP/2 special headers no longer leads to ill-formed header blocks with special headers at the end.
• Vastly improved IPv6 support.
• Fix converting unicode bodies to bytestrings on Python 2.7.
• Allow overriding the HTTP/2 pseudo-headers from the CLI.
• Fixed problems with incorrectly generating the HTTP2-Settings header.
• Improved handling of socket errors.
