| 66 | +<tr><td><details><summary>Fixed <code>initdb</code> to wait for the application user secret before bootstrapping a new cluster</summary><hr/><p>preventing potential race conditions.</p> |

| 76 | +<tr><td><details><summary>Fixed volume snapshot usage during replica scaling to work with backup plugins.</summary><hr/><p>Previously, this optimization was only available with the in-tree backup |
| 77 | +implementation, but now clusters using backup plugins can also leverage volume |
| 78 | +snapshots when creating new replicas.</p> |
