We could do better.

We can declare a `UserBase` model that serves as a base for our other models. And then we can make subclasses of that model that inherit its attributes (type declarations, validation, etc).

All the data conversion, validation, documentation, etc. will still work as normally.

 * New: Support for `HTTP-draft-09/2.0`.
 * New: Support for `spdy/3.1`. Dropped support for `spdy/3`.
 * New: Use ALPN on Android platforms that support it (4.4+)
 * New: CacheControl model and parser.
 * New: Protocol selection in MockWebServer.
 * Fix: Route selection shouldn't use TLS modes that we know will fail.
 * Fix: Cache SPDY responses even if the response body is closed prematurely.
 * Fix: Use strict timeouts when aborting a download.

secure pseudo-random number generator ([CSPRNG](#csprng)). However, in the context of SSE, the MinIO server does not require that the CSPRNG generates values that are indistinguishable from truly random bit strings. Instead, it is sufficient if the generated values are unique - which is a weaker requirement. Nevertheless other parts - for example the TLS-stack - may require that CSPRNG-generated values are indistinguishable from truly random bit strings.
