 # Changelog
 
+## 2025-05-08 - 2.8.6 - fix(tests)
+fix: Improve test stability by handling race conditions in SenderReputationMonitor and IPWarmupManager. Disable filesystem operations and external DNS lookups during tests by checking NODE_ENV, add proper cleanup of singleton instances and active timeouts to ensure consistent test environment.
+
+- Bumped version from 2.8.4 to 2.8.5 in package.json and changelog.md
+- Improved SenderReputationMonitor to skip filesystem operations and DNS record loading when NODE_ENV is set to test
+- Added cleanup of singleton instances and active timeouts in test files
+- Updated readme.plan.md with roadmap items for test stability
+
+## 2025-05-08 - 2.8.5 - fix(tests): Improve test stability by fixing race conditions
+Enhance the SenderReputationMonitor tests to prevent race conditions and make tests more reliable
+
+- Modified SenderReputationMonitor to detect test environment and disable filesystem operations
+- Added proper cleanup of singleton instances and timeouts between tests
+- Disabled DNS lookups during tests to prevent external dependencies
+- Set a consistent test environment using NODE_ENV=test
+- Made all tests independent of each other to prevent shared state issues
+
 ## 2025-05-08 - 2.8.4 - fix(mail)
 refactor(mail): Remove Mailgun references from PlatformService. Update keywords, error messages, and documentation to use MTA exclusively.
