+## Breaking Changes (March 2026)
+
+For consistency, the March 2026 update introduces **pluralized list APIs**, **new outbound destination types**, and updated **constructor/patch models**. These changes require updates to existing client code.
+
+- **Method renames (pluralization)**
+    Update all list calls:
+
+    ```javascript
+    // before
+    const response = await codeEngineService.listAllowedOutboundDestination(params);
+
+    // after
+    const response = await codeEngineService.listAllowedOutboundDestinations(params);
+    ```
+
+    ```javascript
+    // before
+    const response = await codeEngineService.listPersistentDataStore(params);
+
+    // after
+    const response = await codeEngineService.listPersistentDataStores(params);
+    ```
+
+- **Pager class renames**
+    Switch to the new pager names:
+
+    ```javascript
+    // before
+    const pager = new CodeEngineV2.AllowedOutboundDestinationPager(codeEngineService, params);
+
+    // after
+    const pager = new CodeEngineV2.AllowedOutboundDestinationsPager(codeEngineService, params);
+    ```
+
+    ```javascript
+    // before
+    const pager = new CodeEngineV2.PersistentDataStorePager(codeEngineService, params);
+
+    // after
+    const pager = new CodeEngineV2.PersistentDataStoresPager(codeEngineService, params);
+    ```
+
+- **Allowed outbound destination patch payloads changed**
+    Do **not** send `type` in patch payloads anymore. Use the specific fields instead:
+
+    ```javascript
+    // before
+    const patch = {
+      type: 'cidr_block',
+      cidr_block: '10.0.1.0/24',
+    };
+
+    // after (remove type field)
+    const patch = {
+      cidr_block: '10.0.1.0/24',
+    };
+    ```
+
+- **Allowed outbound destination prototypes now require `name`**
+    The `name` field is now required when creating allowed outbound destinations. Ensure you set it for all create flows:
+
+    ```javascript
+    const prototype = {
+      type: 'cidr_block',
+      name: 'allow-all',  // now required
+      cidr_block: '10.0.0.0/24',
+    };
+    ```
+
+    For Private Path service gateway (new type):
+
+    ```javascript
+    const prototype = {
+      type: 'private_path_service_gateway',
+      name: 'pps-to-service-x',
+      private_path_service_gateway_crn: '<private-path-service-gateway-crn>',
+      isolation_policy: 'shared',  // optional: 'shared' or 'dedicated'
+    };
+    ```
+
+> **Action checklist:**
+>
+> - [ ] Rename the list methods and pager classes as shown above.
+> - [ ] Adjust parameter order for CIDR block prototypes (name before cidr_block).
+> - [ ] Remove `type` from allowed-outbound-destination patch payloads.
+> - [ ] Ensure `name` is provided when creating allowed outbound destinations.
+> - [ ] Include the new `private_path_service_gateway` type in any client-side branching/validation.
