 With enhanced monitoring and an improved console experience, these improvements are designed to elevate your cluster management experience.
 
-== Vector Collections (BETA)
+== Lite member management
 
-**Vector Collections** support a specialized type of vector, which is optimized for storing, searching, and managing vector embeddings along with additional metadata. This feature allows you to include metadata values for filtering, processing and detailed analysis of vectors. 
+Hazelcast supports two kinds of members: **Full Members** for when you need to scale both data storage and computational capabilities across the cluster.  **Lite Members** are useful when you need additional computational power or clients that access the data without the overhead of data storage and synchronization.
 
-Management Center 5.5 has additional screens for Vector Collections' metrics. For more information see xref:data-structures:vector-collection.adoc[`Vector Collections`]
+With Platform 5.5, it's possible to execute Jet jobs only on the Lite members and therefore scale computational power independently of storage. Hazelcast has always supported promoting a Lite member to a Full member and in this release you can now demote a Full member to a Lite member. Management Centre supports this functionality.
 
 == Multi-version Rolling Upgrades
 
-Hazelcast Platform 5.5 introduces Long-term Support (LTS) releases to simplify your upgrade experience and give you greater control over when and how you upgrade your software.  It is now possible to upgrade from Hazelcast 5.2.x or later to 5.5 in a single upgrade.

 Management Center 5.5 has been updated to support this multi-version Rolling Upgrade. For more information, see xref:clusters:triggering-rolling-upgrade.adoc[`Triggering a Rolling Upgrade`]
 
 == Multi-member routing for Java clients
 
-Platform 5.5 adds an additional client routing option for Java client applications connecting to geographically dispersed clusters.  Management Center has been updated to support this new Multi-member client routing.

-== Additional Improvements and fixes
+== Slow Operations
+
+Enhanced the Slow Operations reporting to provide information on the operations detected by the SlowOperationsDetector. This detailed information is now included on the members’ listing page, allowing for better identification of potential problems. For further information see xref:clusters:members.adoc#slow-operations[`Slow Operations`]
