In Diablo IV, what is the name of the expansion released in October 2024?

The Diablo IV expansion released in October 2024 is Vessel of Hatred.

Blizzard Entertainment released Vessel of Hatred on October 8, 2024. The expansion continues Diablo IV’s campaign in Nahantu, a jungle region south of the original game’s main settings, and follows the search for Neyrelle after the events involving Mephisto.

Vessel of Hatred introduced the Spiritborn, a new playable class built around mystical spirit guardians. It also expanded the game with new areas, quests, dungeons, mercenaries, and additional progression systems. Its story develops the conflict surrounding Mephisto, the Lord of Hatred.

The title is easy to confuse with earlier Diablo expansions. Lord of Destruction belongs to Diablo II, while Reaper of Souls belongs to Diablo III. Vessel of Hatred is specifically associated with Diablo IV and is the first major expansion for that game.
