Blizzard's Midnight changes disable combat addons in end‑game content while simultaneously rolling out in‑game alternatives, breaking add‑ons that depend on combat‑time data and the combat log. WeakAuras devs say there won't be a WA release for 12.0, so addons relying on COMBAT_LOG_EVENT_UNFILTERED, secure frame/templates or live unit/spell APIs will need redesign or must rely on Blizzard's new built‑in UI systems.
