+This release improves `group by` performance of compressing data and filters,
+introduces the ability to add secondary indexes, and contains the highly upvoted
+community request of transition table support. We recommend that you upgrade at the
+next available opportunity.
 
+**Highlighted features in this release**
+* TAM
+* Significant performance improvements for aggregations using a `group by` with one column
+and/or using a filter clause. SIMD
+* Transition tables
+
+**Dropping support for Bitnami images**
+After the recent change in Bitnami’s [LTS support policy](https://github.com/bitnami/containers/issues/75671),
+we are no longer building Bitnami images for TimescaleDB.
