Do I have to re-root device after miui or hyperOs update?

I want to understand, before I root my device.
If I have rooted my device and do an update, my device will be unroofed?
The bootloader will be still unlocked?
And my apps that require root, will remain?

If you're updating from MIUI EU already then all will be left untouched.
