+# Distributed Data Management Subsystem Changelog
+
+## cl.distributeddatamgr.1 Changed ValuesBucket to a Public Interface
+
+**Change Impact**
+
+For applications developed based on earlier versions, only system applications can use **ValuesBucket**. From this version, **ValuesBucket** can be called by third-party applications.
+
+**Key API/Component Changes**
+
+Before change:
+
+ ```ts
+    /**
+     * Indicates possible value types
+     *
+     * @syscap SystemCapability.DistributedDataManager.DataShare.Core
+     * @systemapi
+     * @StageModelOnly
+     * @since 9
+     */
+    export type ValueType = number | string | boolean;
+ ```
+After change:
+
+ ```ts
+    /**
+     * Indicates possible value types
+     *
+     * @syscap SystemCapability.DistributedDataManager.DataShare.Core
+     * @StageModelOnly
+     * @since 10
+     */
+    export type ValueType = number | string | boolean;
+}
+ ```
+## cl.distributeddatamgr.2 Changed Some Predicate Interfaces in dataSharePredicates to Public Interfaces
+
+**Change Impact**
+
+For applications developed based on earlier versions, only system applications can use **dataSharePredicates**. From this version, on, the namespace **dataSharePredicates**, **dataSharePredicates** class, and some predicate interfaces can be called by third-party applications.
+
+**Key API/Component Changes**
+
+The involved interfaces are as follows:
+
+- equalTo(field: string, value: ValueType): DataSharePredicates
+
+- and(): DataSharePredicates
+
+- orderByAsc(field: string): DataSharePredicates
+
+- orderByDesc(field: string): DataSharePredicates
+
+- limit(total: number, offset: number): DataSharePredicates
+
+- in(field: string, value: Array<ValueType>): DataSharePredicates
