+Fix TypeScript build errors and improve API type safety across platformservice interfaces
+
+- Fixed interface placement in EmailService and MtaConnector classes

+- 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 - 2.8.6 - 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

+## 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.
+
+- Removed Mailgun integration from keywords in package.json and npmextra.json
+- Updated EmailService to remove Mailgun API key usage and reference MTA instead
+- Updated changelog.md and readme.md to reflect removal of Mailgun and update examples
+- Revised error messages to mention 'MTA not configured' instead of generic provider errors
+- Updated readme.plan.md to document Mailgun removal
+
+## 2025-05-08 - 2.8.3 - refactor(mail): Remove Mailgun references
+Remove all Mailgun references from the codebase since it's no longer used as an email provider
+
+- Removed "mailgun integration" from keywords in package.json and npmextra.json
+- Updated comments and documentation in EmailService to remove Mailgun mentions
+- Updated error messages to reference MTA instead of generic email providers
+- Updated the readme email example to use PlatformService reference instead of Mailgun API key
+
+## 2025-05-08 - 2.8.2 - fix(tests)
+Fix outdated import paths in test files for dcrouter and ratelimiter modules
+
+- Updated dcrouter import from '../ts/dcrouter/index.js' to '../ts/classes.dcrouter.js'
+- Updated ratelimiter import from '../ts/mta/classes.ratelimiter.js' to '../ts/mail/delivery/classes.ratelimiter.js'
+
 ## 2025-05-08 - 2.8.1 - fix(readme)
 Update readme with consolidated email system improvements and modular directory structure
