+
+## [7-2] - 2026-04-29
+
+### Added
+- **Housekeeper Interceptor**: Added a PostgreSQL `BEFORE INSERT` trigger to the `housekeeper` table. This trigger dynamically checks `partitions.config` and silently discards Housekeeper tasks (inserts) for any tables managed by the partitioning system. This prevents Zabbix from filling the `housekeeper` table with unnecessary tasks, eliminating Sequential Scans and Table Bloat on the `housekeeper` table, while still allowing tasks for unpartitioned tables (like `events`) to be recorded normally.
+
+## [7-1] - Previous Release
+
+### Added
+- Zabbix 7.0 and 7.4 compatibility.
+- Special handling for the `auditlog` table primary key changes in Zabbix 7.0+.
+- Dynamic creation of partitions and retention management logic.
