+== About release 4.8.1
+
+*Release date* 28 July 2025
+
+This release of {product-title-short} 4.7 provides the following bug fixes:
+
+//ROX-30059 - Dmitrii
+* Before this update, {product-title-short} Central backup failure occurred due to using `pg_dump` version 13 with the PostgreSQL 15 database. This backup failure resulted in data loss for users on version 4.8 with the PostgreSQL 15 databases. With this release, we updated the `pg_dump` version in Central to resolve the backup failures.
+//ROX-30057 - Luis VM
+* Before this update, long network flow update jobs during the 4.8 upgrade caused a 2-hour migration timeout. As a consequence, users experienced a 2-hour outage during the upgrade. With this release, batch network flow updates have been implemented to reduce migration timeouts. As a result, migration timeouts are minimized, reducing the outage window for network flow updates.
+//ROX-29755 - from 4.7.5 notes
+* Before this update, the failure of Sensor to call `stream.Recv()` caused gRPC flow control to block image reprocessing every 4 hours. With this update, the reprocessing loop includes a timeout for sending messages to Sensors, which resolves the issue and resumes the image reprocessing as expected.
+//ROX-29724 - Jouko
+* Before this update, removing a network entity from the network tree did not properly remove its parent node when it had no children or value, leading to a memory leak. As a consequence, users experienced increased memory usage and potential application crashes, particularly noticeable with external IPs enabled. With this release, the memory leak has been fixed by removing parent nodes when nodes are removed from the network tree. As a result, network tree memory usage is optimized, reducing potential crashes and improving system performance, especially with external IPs enabled.
+//ROX-29649 - from 4.7.5 notes
+* Before this update, you could observe excessive logging of telemetry collection status, resulting in log spam. With this update, the telemetry collection has been configured to not emit repeated logs continuously, which resolves the issue and significantly reduces the log volume.
+//ROX-29613 - Oliver
+* Before this update, user-deleted pods were not properly removed from the database, causing stale data to persist and reappear later. As a consequence, stale user data became inaccessible, potentially leading to loss of space and memory exhaustion. With this release, Sensor and Central no longer store information about deleted deployments. As a result, stale data does not persist.
