+### Migration Notes
+
+**For OAuth2 Integration**:
+```swift
+let oauth2 = OAuth2Manager(clientId: "YOUR_CLIENT_ID", clientSecret: "YOUR_SECRET")
+let authUrl = oauth2.requestAuthorization(
+    clientId: "YOUR_CLIENT_ID",
+    scopes: [.identify, .guilds, .email],
+    redirectUri: "https://yourapp.com/callback"
+)
+
+// Exchange code for token
+let token = try await oauth2.exchangeCodeForToken(code: code, redirectUri: redirectUri)
+
+// Token auto-refresh
+let refreshed = try await oauth2.refreshAccessToken(refreshToken: token.refresh_token)
+```
+
+**For Entitlements**:
+```swift
+let entitlements = try await client.getEntitlements(userId: userId)
+if entitlements.contains(where: { $0.sku_id == "123456" }) {
+    // User has entitlement, grant access
+}
+```
+
+**For Polls**:
+```swift
+try await client.createMessagePoll(
+    channelId: channelId,
+    question: "What's your favorite language?",
+    answers: ["Swift", "Python", "Rust"],
+    duration: 3600  // 1 hour
+)
+```
+
+### Known Limitations
+- WebSocket compression (zlib) not yet implemented (Discord provides uncompressed option)
+- Voice activity detection awaiting upstream Discord updates
+- Some sandbox features require special Discord approval
+
+### What's Next
+- WebSocket compression support
+- Advanced voice features
+- Distributed session caching
+- GraphQL support for complex queries
