- **changed** — Replace createMcpHandler(initialize, serverOptions, config) with createMcpHandler(initialize, options) using a single options object combining ServerOptions with serverInfo, verboseLogs, and onEvent, exported as McpHandlerOptions
- **removed** — Remove deprecated 1.x compatibility shims: basePath, streamableHttpEndpoint, sseEndpoint, sseMessageEndpoint, disableSse, redisUrl, maxDuration, and sessionIdGenerator

###### Minor Changes

- 8398dbd: `createMcpHandler(initialize, serverOptions, config)` is now `createMcpHandler(initialize, options)` — a single options object combining the SDK's `ServerOptions` with `serverInfo`, `verboseLogs`, and `onEvent` (exported as `McpHandlerOptions`). The deprecated 1.x compatibility shims (`basePath`, `streamableHttpEndpoint`, `sseEndpoint`, `sseMessageEndpoint`, `disableSse`, `redisUrl`, `maxDuration`, `sessionIdGenerator`) are removed.
