Latest version for Mi Pad 2 can be downloaded from here https://www.androidfilehost.com/?w=files&flid=213123 (MIUI 9) for global* version or from MIUI http://en.miui.com/download-296.html (MIUI 8) for Chinese version.
*Mi pad 2 doesn't really have global version, .EU version comes with pre-installed google services and removed Chinese bloatware.
This is a bad news for Mi Pad 2 owners because they do not have any solid custom ROM support for their device, which is due to lack of propitiatory Intel Atom's source code. So even if developers tried hard to deliver custom ROM they simply cannot. So unlike Mi Pad 1 even if Xiaomi EoL'd the support in a similar way last week, they can still get custom ROMs and patch support as long as developers delivers them. But for Mi Pad 2 it is simply not possible.
