 # Changelog
 
+## 2025-09-12 - 4.3.0 - feat(smartnetwork)
+Add randomizable port search and switch DNS resolution to @push.rocks/smartdns; export smartdns and update docs
+
+- findFreePort: added options.randomize (IFindFreePortOptions) to return a random available port within a range; retains default sequential search behavior
+- resolveDns: switched to @push.rocks/smartdns client with 'prefer-system' strategy and DoH fallback; now returns parsed A, AAAA and MX records
+- Exported smartdns from the internal plugins module and added @push.rocks/smartdns dependency
+- Documentation updates: readme clarifies random port selection, DNS resolution strategy and adds examples for random findFreePort usage
+- Bumped @git.zone/tstest dev dependency to ^2.3.7
+
 ## 2025-09-12 - 4.2.0 - feat(PublicIp)
 Add PublicIp service and refactor SmartNetwork to use it; remove public-ip dependency; update exports, docs and dependencies
