 # Changelog

+## 2025-05-08 - 2.8.9 - fix(types)
+Fix TypeScript build errors and improve API type safety across platformservice interfaces
+
+- Fixed interface placement in EmailService and MtaConnector classes
+- Aligned DeliveryStatus enum and updated ApiManager handlers with proper type-safe signatures
+- Added comprehensive TypeScript interfaces for ISendEmailOptions, ITemplateContext, IValidateEmailOptions, IValidationResult, and IEmailServiceStats
+- Removed circular dependencies in type definitions and added proper type assertions
+- Improved test stability by handling race conditions in SenderReputationMonitor and IPWarmupManager; external DNS lookups are disabled under test environment
+
+## 2025-05-08 - 2.8.8 - fix(types): Fix TypeScript build errors and improve API interfaces
+Fix TypeScript build errors caused by interface placement and improve API type alignment
+
+- Fixed interface placement in EmailService and MtaConnector classes
+- Aligned DeliveryStatus enum with EmailSendJob implementation
+- Added proper method signatures for API endpoint handlers in ApiManager class
+- Updated getStats and checkEmailStatus methods to conform to API contracts
+- Implemented type-safe return values for all API methods
+- Fixed circular dependencies in type definitions
+- Added proper type assertion where needed to satisfy TypeScript compiler
+
+## 2025-05-08 - 2.8.7 - feat(types): Add comprehensive TypeScript interfaces for API types
+Improve type safety across the platform by adding detailed TypeScript interfaces for APIs
+
+- Added ISendEmailOptions interface with complete documentation for email sending options
+- Created ITemplateContext interface for email template rendering with full type safety
+- Added IValidateEmailOptions and IValidationResult interfaces for email validation
+- Improved IEmailServiceStats interface with detailed statistics types
+- Added IEmailStatusResponse and IEmailStatusDetails interfaces for MTA status checking
+- Updated sendEmail and other methods to use these new interfaces instead of 'any'
+- Removed need for type assertions in various components
+
 ## 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.
