Build of October 17, 2026 — Blizzard forum: Kaivax, Datamined in the Latest Beta Build, Kaivax

What changed

Client New in the files: a pet called Blossoming Ancient, others called Pinky and Gill'el, a Verdant Sea Turtle, a Stillwater Fisher outfit, a Gilded Blademaster set and a Rugged Totemic Backpack. 134 changed rows in the tracker's count, all of them additions.
Systems Blizzard on the same evening, without naming the items: the art assets datamined from the latest beta build "are not intended for this version of World of Warcraft".

We did not read this build. There is no snapshot of its talent trees here, so there is nothing to compute - and an empty table would read as "nothing changed", which is a different statement.
