 # Changelog
 
+## 2025-04-19 - 7.1.2 - fix(networkproxy/requesthandler)
+Improve HTTP/2 request handling and error management in the proxy request handler; add try-catch around routing and update header processing to support per-backend protocol overrides.
+
+- Wrapped the routing call (router.routeReq) in a try-catch block to better handle errors and missing host headers.
+- Returns a 500 error and increments failure metrics if routing fails.
+- Refactored HTTP/2 branch to copy all headers appropriately and map response headers into HTTP/1 response.
+- Added support for per-backend protocol override via the new backendProtocol option in IReverseProxyConfig.
+
+## 2025-04-19 - 7.1.1 - fix(commit-info)
+Update commit metadata and synchronize project configuration (no code changes)
+
+- Verified that all files remain unchanged
+- Commit reflects a metadata or build system sync without functional modifications
+
+## 2025-04-19 - 7.1.0 - feat(core)
+Add backendProtocol option to support HTTP/2 client sessions alongside HTTP/1. This update enhances NetworkProxy's core functionality by integrating HTTP/2 support in server creation and request handling, while updating plugin exports and documentation accordingly.
+
+- Introduced 'backendProtocol' configuration option (http1 | http2) with default 'http1'.
+- Updated creation of secure server to use http2.createSecureServer with HTTP/1 fallback.
+- Enhanced request handling to establish HTTP/2 client sessions when backendProtocol is set to 'http2'.
+- Exported http2 module in plugins.
+- Updated readme.md to document backendProtocol usage with example code.
+
+## 2025-04-05 - 7.0.1 - fix(package.json)
+Update packageManager field in package.json to specify the pnpm version for improved reproducibility.
+
+- Added the packageManager field to clearly specify the pnpm version and its checksum.
+
+## 2025-04-04 - 7.0.0 - BREAKING CHANGE(redirect)
+Remove deprecated SSL redirect implementation and update exports to use the new redirect module
+
+- Deleted ts/classes.sslredirect.ts which contained the old SSL redirect logic
+- Updated ts/index.ts to export 'redirect/classes.redirect.js' instead of the removed SSL redirect module
+- Adopted a new redirect implementation that provides enhanced features and a more consistent API
+
+## 2025-03-25 - 6.0.1 - fix(readme)
+Update README documentation: replace all outdated 'PortProxy' references with 'SmartProxy', adjust architecture diagrams, code examples, and configuration details (including correcting IPTables to NfTables) to reflect the new naming.
+
+- Renamed 'PortProxy' to 'SmartProxy' in diagrams, flow sequences, and descriptive text
+- Updated code examples and installation instructions accordingly
+- Corrected references from IPTables to NfTables for modern system support
+
+## 2025-03-18 - 5.1.0 - feat(docs)
+docs: replace IPTablesProxy references with NfTablesProxy in README and examples, updating configuration options and diagrams for advanced nftables features
+
+- Updated README diagrams to reflect nftables integration for low-level port forwarding.
+- Replaced all occurrences of 'IPTablesProxy' with 'NfTablesProxy' in documentation and code examples.
+- Included additional details on QoS, advanced NAT, and IP set options in the configuration options section.
+
 ## 2025-03-18 - 5.0.0 - BREAKING CHANGE(nftables)

+## Configuration Options
+
+### backendProtocol
+
+Type: 'http1' | 'http2' (default: 'http1')
+
+Controls the protocol used when proxying requests to backend services. By default, the proxy uses HTTP/1.x (`http.request`). Setting `backendProtocol: 'http2'` establishes HTTP/2 client sessions (`http2.connect`) to your backends for full end-to-end HTTP/2 support (assuming your backend servers support HTTP/2).
+
+Example:
+```js
+import { NetworkProxy } from '@push.rocks/smartproxy';
+
+const proxy = new NetworkProxy({
+  port: 8443,
+  backendProtocol: 'http2',
+  // other options...
+});
+proxy.start();
