 # Changelog
 
+## 2026-04-30 - 7.9.2 - fix(test)
+stabilize DNS availability tests with deterministic records and shorter retries
+
+- replace the external TXT record lookup with a localhost A record check to avoid network-dependent test behavior
+- reduce retry count and delay in failing checkUntilAvailable assertions to keep test runs faster and more predictable
+
 ## 2026-04-30 - 7.9.1 - fix(client,testing,build)
 improve TypeScript compatibility for DNS client parsing and test suite
