 - [**Improve partitioning user experience**](../v19.2/partitioning.html): CockroachDB now prevents users from specifying a non-partitioned secondary index on a partitioned table by default to improve performance. Users will have the ability to override this default as it may be necessary in some rare use cases. Additionally, users can now specify the same name for the partition for tables and for all corresponding indexes.
 - [**Improve setting of zone configs via SQL**](../v19.2/configure-zone.html): You can now use the CLI or SQL shell to retrieve locality. [`ALTER TABLE`](../v19.2/alter-table.html) now returns an error when users select conflicting or impossible zone constraints due to user error.
 - **Make it easy to focus queries on partitioned data**: CockroachDB now automatically limits a query to only the applicable [partition](../v19.2/partitioning.html) without having to specify the particular partition for a geo-distributed table. This prevents the query from conducting a full table scan.
+- **Improve decommissioning, recommissioning, and recovery of killed nodes**: Improved ability to change cluster membership during expected ([decommissioning](../v19.2/remove-nodes.html), [recommissioning](../v19.2/remove-nodes.html#recommission-nodes)) and unexpected (killed nodes) events without impact stability or performance.
+- **Better insight into constraint conformance**: You can now tell if your cluster is in a healthy state based on the status of conformance to constraints like [zone configurations](../v19.2/configure-replication-zones.html), lease preferences, and replica diversification.
