G998U1UES4AUIN firmware is available for download via Odin, and OTA from many carriers (see list at sammobile.com). It has the October 1 security patch level. As the S (rather than U) before the bootloader number tells us, it is a security update only, with no new features.
 
Thanks for the heads up on this. Patch is now available for unlocked devices on the Spectrum Mobile network.
