Changelog: chatgpt.com (20260827-025209Z → 20260827-225223Z)

Official release notes

• More controls in temporary chat (2026-08-27): Temporary chats can start personalized (memory, plugins, custom instructions from regular settings; no new memories; stay out of history unless saved) or non-personalized (default — no memory/instructions/plugins). Personalization is set only at start. You can save a temporary chat into normal history; it then follows account personalization and model-improvement prefs.
