+## File Format Change
+**[IMPORTANT]** This version includes a backward incompatible file format change for YSQL. This
+means that if you have an existing cluster with YSQL schema, then you will not be able to connect to
+the YSQL database after upgrading to v1.2.9. There are two ways to work around this problem:
+
+* If you don't care about preserving your existing data, then delete your cluster,
+  and create a new cluster with 1.2.9. 
+* If you want to continue using your existing data, then please save your data (in the form of
+  SQL statements), delete the cluster, create a new cluster with 1.2.9 and then load
+  the previously saved data.
+
