 * CMake: add option `-DCUSTOM_LSB_RELEASE_PATH` to specify the path of `lsb-release` file
     * `-DCUSTOM_OS_RELEASE_PATH` has been supported since `v2.11.4`
 * Report more SOC names on Android (CPU, Android)
+* Support duration printing in custom format (Disk / Users)
+    * For example:  
+```json
+{
