 # Changelog
 
+## 2025-05-19 - 19.2.6 - fix(tests)
+Adjust test cases for ACME challenge route handling, mutex locking in route updates, and port management. Remove obsolete challenge-route lifecycle tests and update expected outcomes in port80 management and race condition tests.
+
+- Remove test file 'test.challenge-route-lifecycle.node.ts'
+- Rename 'acme-route' to 'secure-route' in port80 management tests to avoid confusion
+- Ensure port 80 is added only once when both user routes and ACME challenge use the same port
+- Improve mutex locking tests to guarantee serialized route updates with no concurrent execution
+- Adjust expected certificate manager recreation counts in race conditions tests
+
 ## 2025-05-19 - 19.2.5 - fix(acme)
 Fix port 80 ACME management and challenge route concurrency issues by deduplicating port listeners, preserving challenge route state across certificate manager recreations, and adding mutex locks to route updates.
