2025-12 Monthly Summary (mathesar-foundation/mathesar): Implemented a critical fix to timezone-aware datetime handling in Distinct List serialization. Added serialization helpers to ensure JSON-serializable outputs and applied serialization across all result rows, stabilizing Distinct List results for Time with Timezone columns and preventing the Django REST Framework error: 'JSON can't represent timezone-aware times' (Issue #2964). The change reduces runtime errors and improves reliability for time-related data processing, exports, and dashboards. Commit reference: 1af7b56896a32817c7a796472d8679b62455a033. Technologies involved include Python, timezone-aware datetime handling, and Django REST Framework serialization utilities.
