 # Changelog
 
+## 2026-01-30 - 22.4.1 - fix(smartproxy)
+improve certificate manager mocking in tests, enhance IPv6 validation, and record initial bytes for connection metrics
+
+- Add createMockCertManager and update tests to fully mock createCertificateManager to avoid real ACME calls and make provisioning deterministic
+- Record initial data chunk bytes in route-connection-handler and report them to metricsCollector.recordBytes to improve metrics accuracy
+- Improve IPv6 validation regex to accept IPv6-mapped IPv4 addresses (::ffff:x.x.x.x)
+- Add/set missing mock methods used in tests (setRoutes, generateConnectionId, trackConnectionByRoute, validateAndTrackIP) and small test adjustments (route names, port changes)
+- Make test robustness improvements: wait loops for connection cleanup, increase websocket keepalive timeout, and other minor test fixes/whitespace cleanups
+- Update certificate meta timestamps (test fixtures)
+
+## 2026-01-30 - 22.4.0 - feat(smart-proxy)
+calculate when SNI is required for TLS routing and allow session tickets for single-target passthrough routes; add tests, docs, and npm metadata updates
+
+- Add calculateSniRequirement() and isWildcardOnly() to determine when SNI is required for routing decisions
+- Use the new calculation to allow TLS session tickets for single-route passthrough or wildcard-only domains and block them when SNI is required
+- Replace previous heuristic in route-connection-handler with the new SNI-based logic
+- Add comprehensive unit tests (test/test.sni-requirement.node.ts) covering multiple SNI scenarios
+- Update readme.hints.md with Smart SNI Requirement documentation and adjust troubleshooting guidance
+- Update npmextra.json keys, add release registries and adjust tsdoc/CI metadata
+
+## 2026-01-30 - 22.3.0 - feat(docs)
+update README with installation, improved feature table, expanded quick-start, ACME/email example, API options interface, and clarified licensing/trademark text
+
+- Added Installation section with npm/pnpm commands
+- Reformatted features into a markdown table for clarity
+- Expanded Quick Start example and updated ACME email placeholder
+- Added an ISmartProxyOptions interface example showing acme/defaults/behavior options
+- Clarified license file path and expanded trademark/legal wording
+- Minor editorial and formatting improvements throughout the README
+
 ## 2026-01-30 - 22.2.0 - feat(proxies)
 introduce nftables command executor and utilities, default certificate provider, expanded route/socket helper modules, and security improvements

+### Smart SNI Requirement (v22.3+)
+
+SmartProxy automatically determines when SNI is required for routing. Session tickets (TLS resumption without SNI) are now allowed in more scenarios:
+
+**SNI NOT required (session tickets allowed):**
+- Single passthrough route with static target(s) and no domain restriction
+- Single passthrough route with wildcard-only domain (`*` or `['*']`)
+- TLS termination routes (`terminate` or `terminate-and-reencrypt`)
+- Mixed terminate + passthrough routes (termination takes precedence)
+
+**SNI IS required (session tickets blocked):**
+- Multiple passthrough routes on the same port (need SNI to pick correct route)
+- Route has dynamic host function (e.g., `host: (ctx) => ctx.domain === 'api.example.com' ? 'api-backend' : 'web-backend'`)
+- Route has specific domain restriction (e.g., `domains: 'api.example.com'` or `domains: '*.example.com'`)
+
+This allows simple single-target passthrough setups to work with TLS session resumption, improving performance for clients that reuse connections.
+
 ### Troubleshooting
 
 **"No SNI detected" errors**:
 - Client is using TLS session resumption without SNI
-- Solution: Configure route for TLS termination (allows session resumption)
+- Solution: Configure route for TLS termination (allows session resumption), or ensure you have a single-target passthrough route with no domain restrictions
 
 **"HttpProxy not available" errors**:
 - `useHttpProxy` not configured for the port

 ### Certificate Issues
-- ✅ Ensure domain points to your server
+- ✅ Ensure domain DNS points to your server
-- ✅ Port 80 must be accessible for ACME challenges
+- ✅ Port 80 must be accessible for ACME HTTP-01 challenges
-- ✅ Check DNS propagation with `nslookup`
+- ✅ Check DNS propagation with `dig` or `nslookup`
-- ✅ Verify email in ACME configuration
+- ✅ Verify the email in ACME configuration is valid
 
 ### Connection Problems
-- ✅ Check route priorities (higher = matched first)
+- ✅ Check route priorities (higher number = matched first)
-- ✅ Verify security rules aren't blocking
+- ✅ Verify security rules aren't blocking legitimate traffic
-- ✅ Test with `curl -v` for detailed output
+- ✅ Test with `curl -v` for detailed connection output
-- ✅ Enable debug mode for verbose logging
+- ✅ Enable debug logging for verbose output
 
 ### Performance Tuning
-- ✅ Use NFTables for high-traffic routes
+- ✅ Use NFTables forwarding for high-traffic routes (Linux only)
-- ✅ Enable connection pooling
+- ✅ Enable connection keep-alive where appropriate
-- ✅ Adjust keep-alive settings
+- ✅ Monitor metrics to identify bottlenecks
-- ✅ Monitor with built-in metrics
+- ✅ Adjust `maxConnections` based on your server resources
 
 ### Debug Mode
