 # Changelog
 
+## 2025-03-15 - 1.1.1 - fix(mta)
+Refactor API Manager and DKIMCreator: remove Express dependency in favor of Node's native HTTP server, add an HttpResponse helper to improve request handling, update path and authentication logic, and expose previously private DKIMCreator methods for API access.
+
+- Replaced Express-based middleware with native HTTP server handling, including request body parsing and CORS headers.
+- Introduced an HttpResponse helper class to standardize response writing.
+- Updated route matching, parameter extraction, and error handling within the API Manager.
+- Modified DKIMCreator methods (createDKIMKeys, storeDKIMKeys, createAndStoreDKIMKeys, and getDNSRecordForDomain) from private to public for better API accessibility.
+- Updated plugin imports to include the native HTTP module.
+
 ## 2025-03-15 - 1.1.0 - feat(mta)
 Enhance MTA service and SMTP server with robust session management, advanced email handling, and integrated API routes
