### User Interface Language

Fess determines the UI language in this order:

 * 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.

- **SMB 3.0.2**: Windows 8.1/Server 2012R2 (0x0302) - Enhanced encryption
- **SMB 3.1.1**: Windows 10/Server 2016+ (0x0311) - AES-128-GCM + Pre-Auth Integrity

**Protocol Selection:**
- Default Range: SMB1 to SMB 3.1.1
- Automatic Negotiation: Client offers all supported dialects, server selects highest common version
- Configurable: Min/max versions can be set via configuration properties
