• Supports force_compaction on sinks to enable buffering and compaction of updates when the stream key is the same as the primary key. #23681

Installation and deployment

• Counts the CPU cores of all nodes (instead of only compute nodes) in the cluster against the cpu_core_limit specified in the license key. #23390
• Changes cpu_core_limit in the license key to rwu_limit to limit both CPU cores and total cluster memory. #23403
• Breaking change: Requires the correct aud claim for authentication. #23155
• Supports LDAP authentication to verify users against an external LDAP directory server. #23150

Cluster configuration changes

• Adds session variable enable_index_selection to control whether to enable index selection for both streaming and batch queries. #23092
• Technical preview: Adds session variable enable_locality_backfill to control locality backfilling, which extends index-based optimizations to the entire backfill pipeline. #23275
