Highlights
This release focuses on chat reliability and sign-in polish. Long conversations now load older messages on demand, interrupted chats recover gracefully without losing your output, and organizations on a custom domain land on their branded sign-in host.
New features
Chat history pagination
Long conversations no longer reload everything at once. Older messages are now fetched on demand as you scroll, so jumping back into a long-running chat is faster and lighter.
Improvements
More resilient chat
- Cancelled or interrupted chats now recover gracefully, with partial output preserved instead of lost
- Chat and tool payload limits are tighter to reduce oversized-message failures
- Stale state issues that could hide messages have been fixed
Image generation reliability
Image generation now handles inputs more forgivingly, reducing confusing argument errors when prompts include numeric values.
Web search clarity
Tooltips on the web search toggle now match actual behavior, removing a small but persistent source of confusion.
Bug fixes
Various fixes to chat streaming, authentication flows, sandbox reliability, and snapshot handling.
