 ## 2.8 Release Notes
 
+### 2.8.5 Release Notes
+
+#### Release Date xx
+
+#### Release Highlights
+
+This release enhances the operational reliability of MDCB. We've resolved a synchronization issue where MDCB would permanently stop syncing with Gateways after Redis connection failures by implementing intelligent exponential backoff retry logic, ensuring continuous operation during Redis outages and network disruptions.
+Additionally, we've upgraded the platform to Golang 1.24, strengthening security through the latest language improvements and maintaining our commitment to using current, supported runtime environments.
+
+For a comprehensive list of changes, please refer to the detailed [changelog]({{< ref "#Changelog-v2.8.5" >}}).

+<summary>Enhanced Redis Connection Resilience with Intelligent Retry Logic</summary>
+
+We've resolved a synchronization issue where MDCB would permanently stop syncing with Gateways after Redis connection failures. The system now implements robust exponential backoff retry logic that continues indefinitely until a successful reconnection is achieved, ensuring your API infrastructure maintains continuous operation during Redis outages, network disruptions, or server restarts. 
+
+Previously, MDCB would attempt only a single reconnection before silently abandoning the sync process while appearing healthy, leaving Gateways without updates. 
+
+With this enhancement, both pub/sub and keyspace listeners automatically recover from transient Redis issues, provide clear logging of retry attempts for improved observability, and eliminate the need for manual MDCB restarts to restore synchronization.
