+### Postgres query insights (private preview) {#postgres-query-insights}
+
+A new **Query insights** tab is now available in [ClickHouse Cloud Managed Postgres](/cloud/managed-postgres) (Private Preview). It ranks every query pattern by impact and shows why each one is slow across three surfaces:
+
+* **Overview** — one-screen database health
+* **Patterns** — table sortable by runtime, CPU, errors, and P95
+* **Per-pattern flyout** — latency percentiles, CPU vs I/O, cache vs disk, temp spills, parallel-worker shortfalls, and WAL volume
+
+Powered by [pg_stat_ch](https://github.com/ClickHouse/pg_stat_ch), an open-source Postgres extension.
+
+### Data catalog integration expansions {#data-catalog-integration-expansions}
+
+We have expanded our support of [data catalog integrations](/manage/data-catalogs) via the Data Sources UI with more auth methods, table formats, and data catalog flavors:
+
+* IAM support for [AWS Glue Catalog](/use-cases/data-lake/glue-catalog)
+* [BigLake Metastore](/use-cases/data-lake/biglake-catalog) support for data catalog integration
+* Delta Tables support on [Unity Catalog](/use-cases/data-lake/unity-catalog)
