+ * Iceberg always use the latest stable format version when creating a new
table.
+ * This reserved property keyword allows users to override the Iceberg
format version of the table metadata.
+ * <p>
+ * If this table property exists when creating a table, the table will use
the specified format version.
+ * If a table updates this property, it will try to upgrade to the specified
format version.
+ * This helps developers to try out new features in an unreleased version or
migrate existing tables to a new version.
+ * <p>
+ * Note: If you set the Iceberg format to an unreleased version, software
stability is not guaranteed.
Review comment:
This reserved property should not allow setting the format version to
anything other than a stable and adopted version.
