February 2026: Delivered external message routing filter for MongooseIM (mod_external_filter) that delegates routing permissions to an external service, enabling policy-driven message flow based on external criteria. Implemented an external_filter_mock to simulate the external decision service and support robust end-to-end tests. Added tests for mod_external_filter to validate integration and behavior. Updated documentation and MkDocs configuration to reflect the new feature, usage, and testing strategy. Added config parser tests and aligned behavior with documentation, including making pool_tag a required option and updating mod_stanzaid entries. There were no major bugs fixed this month; focus was on feature delivery, test coverage, and documentation improvements. Technologies demonstrated include Erlang/MongooseIM module development, HTTP integration, test automation, and MkDocs documentation.

December 2025 monthly summary for esl/MongooseIM focusing on the 6.5.0 release. Delivered a comprehensive release with new user-facing features and improvements, plus extensive documentation updates. Key improvements include TLS connections for Redis and RabbitMQ, XEP-0402 PEP Native Bookmarks support, upgraded dependencies, and refined migration and admin guidance.

November 2025: Targeted improvements in room creation error handling across MUC and GraphQL/XMPP integration in esl/MongooseIM. Focused on delivering precise error signaling, improved user feedback, and stronger test coverage. All changes centered on business value: clearer error messages reduce support load and speed up troubleshooting, while the code cleanup enhances maintainability across protocols.

July 2025 (2025-07) monthly summary for esl/MongooseIM: Delivered a privacy-centric feature to block users in group chats (MUC and MUC light), with tests, documentation updates, and config loading improvements. The changes ensure blocked users' messages are ignored in group chats, and blockers are protected from incoming messages from blocked users in those environments. A minor refactor improved mod_muc_light config loading, and docs were updated to clarify blocking behavior in group chat contexts. This work enhances enterprise moderation controls and user privacy while maintaining system stability.

June 2025 monthly summary for esl/MongooseIM focusing on MUC interoperability and test coverage. Delivered a critical bug fix to MUC namespace handling in room presence and added regression tests to prevent namespace regressions. Improvements enhance interoperability and stability in multi-user chat scenarios, reducing cross-vendor interoperability issues and future regressions.
