bodudek No, it is not. 250905 is the last "public" (stable) version. There are beta versions. And the last one is 251104. You can find it here
In order to get it you must install it through the classic method. Download the archive, extract it to a PC hard drive, copy the files (not the folder) to the root of a USB drive and insert the USB drive in one of the USB ports connected to the DUDU device. The USB drive must be FAT32 formatted. A message that "an update is available" should appear. Do not extract the USB drive during the update, you'll get a green color message that it will tell you "please extract the USB drive" or something like that. After the successful update, you can enable Beta App Access and Auto Check for updates in the Settings/More features/Appstore so you can get updates through OTA.
