Xz1 annoyingly slow updates and regions issue.

Could someone please explain why my NEW Xz1 phone (and Sony companion) think that I have the latest updates when according to XperiFirm much newer versions exist. Currently I have:

47.1.A.2.281 currently installed on the phone yet
47.1.A.12.235 is the latest available in other geographical areas.

Is it ok to flash this latest one from a different geographical area onto my phone ?
I live in New Zealand and was considering flashing a UK Customized 47.1.A.12.235
I would use Flashtool by Androxyde.
Would this void my warranty ?

Why is it that Sony put out updates but we just don't get to see them - who's dragging the chain here ?

And since posting the above I'm aware that two more updates have happened:

47.1.A.12.270
47.1.A.16.20

WTF is going on ? Why are we not getting ANY updates ?

You can flash firmware from other region, but you may lose FOTA update pushes, this means you can only upgrade your firmware through Flashtool or other similar tools in the future.
As for the warranty, I have no idea about it, but I have already flashed my Chinese version XZ1 to Malaysian firmware, since the Chinese firmware does not have any Google apps, and it just works fine, I also replaced the oem.sin file from Chinese firmware to Malaysian firmware in order to have VoLTE enabled.
But as I mentioned before, I lose FOTA after flashed my phone, so I have to download the entire firmware via XperiFirm and flash it manually. If you flash the original firmware without modifications, you may not lose FOTA, if you do so, please tell me!

EDIT: You can only flash firmware matches your model, so don't flash a G8342 firmware into a G8341 or other.
