+#### Improvements
+
+* Mendix Cloud database backups are now created with `pg_dump` version `1.16`. This version has been included with PostgreSQL since September 2024 as part of PostgreSQL 17. As a result, backups created in Mendix Cloud can only be restored with `pg_restore` version `1.16` or above (PostgreSQL 17 or above).
+
+    If you attempt to restore a backup using an earlier version, you will receive the following error: `pg_restore: [archiver] unsupported version (1.16) in the file header`. To resolve this issue, upgrade your software to a version that includes newer versions of `pg_dump` and `pg_restore`. 
+
+    Backups created in Mendix Cloud before June 9, 2026, continue to work as expected after you upgrade your local PostgreSQL binaries to newer versions.
