Sometimes five seconds just isn't enough. This release fixes an HTTP transport bug that was cutting connections short, along with OAuth and Redis fixes, better ASGI support, and CLI update notifications so you never miss a beat.

⏱️ **HTTP transport timeout fix** restores MCP's 30-second default connect timeout, which was incorrectly defaulting to 5 seconds.

🔧 **Infrastructure fixes** including OAuth token storage TTL, Redis key prefixing for ACL isolation, and ContextVar propagation for ASGI-mounted servers with background tasks.
