 # Changelog
 
+## 2025-05-19 - 19.3.7 - fix(smartproxy)
+Improve error handling in forwarding connection handler and refine domain matching logic
+
+- Add new test 'test.forwarding-fix-verification.ts' to ensure NFTables forwarded connections remain open
+- Introduce setupOutgoingErrorHandler in route-connection-handler.ts for clearer, unified error reporting during outgoing connection setup
+- Simplify direct connection piping by removing manual data queue processing in route-connection-handler.ts
+- Enhance domain matching in route-manager.ts by explicitly handling routes with and without domain restrictions
+
+## 2025-05-19 - 19.3.6 - fix(tests)
+Fix route configuration property names in tests: replace 'acceptedRoutes' with 'routes' in nftables tests and update 'match: { port: ... }' to 'match: { ports: ... }' in port forwarding tests.
+
+- Renamed 'acceptedRoutes' to 'routes' in test/nftables-forwarding.ts for alignment with the current SmartProxy API.
+- Changed port matching in test/port-forwarding-fix.ts from 'match: { port: ... }' to 'match: { ports: ... }' for consistency.
+
+## 2025-05-19 - 19.3.6 - fix(tests)
+Update test route config properties: replace 'acceptedRoutes' with 'routes' in nftables tests and change 'match: { port: ... }' to 'match: { ports: ... }' in port forwarding tests
+
+- In test/nftables-forwarding.ts, renamed property 'acceptedRoutes' to 'routes' to align with current SmartProxy API.
+- In test/port-forwarding-fix.ts, updated 'match: { port: 9999 }' to 'match: { ports: 9999 }' for consistency.
+
+## 2025-05-19 - 19.3.5 - fix(smartproxy)
+Correct NFTables forwarding handling to avoid premature connection termination and add comprehensive tests
+
+- Removed overly aggressive socket closing for routes using NFTables forwarding in route-connection-handler.ts
+- Now logs NFTables-handled connections for monitoring while letting kernel-level forwarding operate transparently
+- Added and updated tests for connection forwarding, NFTables integration and port forwarding fixes
+- Enhanced logging and error handling in NFTables and TLS handling functions
+
+## 2025-05-19 - 19.3.4 - fix(docs, tests, acme)
+fix: update changelog, documentation, examples and tests for v19.4.0 release. Adjust global ACME configuration to use ssl@bleu.de and add non-privileged port examples.
+
+- Updated changelog with new v19.4.0 entry detailing fixes in tests and docs
+- Revised README and certificate-management.md to demonstrate global ACME settings (using ssl@bleu.de, non-privileged port support, auto-renewal configuration, and renewCheckIntervalHours)
+- Added new examples (certificate-management-v19.ts and complete-example-v19.ts) and updated existing examples (dynamic port management, NFTables integration) to reflect v19.4.0 features
+- Fixed test exports and port mapping issues in several test files (acme-state-manager, port80-management, race-conditions, etc.)
+- Updated readme.plan.md to reflect completed refactoring and breaking changes from v19.3.3
+
+## 2025-05-19 - 19.4.0 - fix(tests) & docs
+Fix failing tests and update documentation for v19+ features
+
+- Fix ForwardingHandlerFactory.applyDefaults to set port and socket properties correctly
+- Fix route finding logic in forwarding tests to properly identify redirect routes
+- Fix test exports in acme-state-manager.node.ts, port80-management.node.ts, and race-conditions.node.ts
+- Update ACME email configuration to use ssl@bleu.de instead of test domains
+- Update README with v19.4.0 features including global ACME configuration
+- Update certificate-management.md documentation to reflect v19+ changes
+- Add new examples: certificate-management-v19.ts and complete-example-v19.ts
+- Update existing examples to demonstrate global ACME configuration
+- Update readme.plan.md to reflect completed refactoring
+
 ## 2025-05-19 - 19.3.3 - fix(core)
 No changes detected – project structure and documentation remain unchanged.

 3. **Permission errors**: Ensure the certificate directory is writable

-# SmartProxy Architecture Refactoring Plan
+# SmartProxy v19.4.0 - Completed Refactoring
 
 ## Overview
 
-Refactor the proxy architecture to provide clearer separation of concerns between HTTP/HTTPS traffic handling and low-level connection routing.
+SmartProxy has been successfully refactored with clearer separation of concerns between HTTP/HTTPS traffic handling and low-level connection routing. Version 19.4.0 introduces global ACME configuration and enhanced route management.
 
-## Current Architecture Problems
+## Current Architecture (v19.4.0)
 
-1. NetworkProxy name doesn't clearly indicate it handles HTTP/HTTPS
+### HttpProxy (formerly NetworkProxy)
-2. HTTP parsing logic is duplicated in RouteConnectionHandler
-3. Redirect and static route handling is embedded in SmartProxy
-4. Unclear separation between TCP routing and HTTP processing
-
-## Proposed Architecture
-
-### HttpProxy (renamed from NetworkProxy)
 **Purpose**: Handle all HTTP/HTTPS traffic with TLS termination
 
-**Responsibilities**:
+**Current Responsibilities**:
 - TLS termination for HTTPS
 - HTTP/1.1 and HTTP/2 protocol handling
 - HTTP request/response parsing

+**Purpose**: Central API for all proxy needs with route-based configuration

+- Route-level certificate overrides
-2. **Update class and file names**

 4. Protocol-specific optimizations
 5. Better HTTP/2 multiplexing
 
-## Breaking Changes
+## Breaking Changes from v18 to v19
 
 1. `NetworkProxy` class renamed to `HttpProxy`
 2. Import paths change from `network-proxy` to `http-proxy`
-3. Some type names may change for consistency
+3. Global ACME configuration now available at the top level
+4. Certificate management unified under SmartCertManager
 
-## Rollback Plan
+## Future Enhancements
 
-If issues arise:
+1. HTTP/3 (QUIC) support in HttpProxy
-1. Git revert to previous commit
+2. Advanced HTTP features (compression, caching)
-2. Re-deploy previous version
+3. HTTP middleware system
-3. Document lessons learned
+4. Protocol-specific optimizations
-4. Plan incremental changes
+5. Better HTTP/2 multiplexing
+6. Enhanced monitoring and metrics
+
+## Key Features in v19.4.0
+
+1. **Global ACME Configuration**: Default settings for all routes with `certificate: 'auto'`
+2. **Enhanced Route Management**: Better separation between routing and certificate management
+3. **Improved Test Coverage**: Fixed test exports and port bindings
+4. **Better Error Messages**: Clear guidance for ACME configuration issues
+5. **Non-Privileged Port Support**: Examples for development environments
