</Info>

A major release featuring a completely redesigned composer, comprehensive chat management, and team-scoped assistants.

## Composer Redesign

The chat composer has been rebuilt with a cleaner, more flexible action bar.

<CardGroup cols={2}>
  <Card title="Context Menu" icon="sliders">
    New menu button opens a structured dropdown with nested submenus for all chat controls — replacing the crowded horizontal toolbar.
  </Card>

  <Card title="Pinnable Actions" icon="thumbtack">
    Pin your most-used controls (model, assistant, thinking, web search, context, profiles) to the composer bar. Persisted across sessions.
  </Card>

  <Card title="Profile Selector" icon="user">
    Switch enterprise profiles directly from the composer bar or context menu.
  </Card>

  <Card title="Assistant Indicator" icon="robot">
    Selected assistant is clearly displayed above the composer input with name and icon.
  </Card>

## Chat Management

New tools for organising and managing your conversations.

<AccordionGroup>
  <Accordion title="Pinned Notes" icon="note-sticky">
    Pin key insights from assistant messages as notes — displayed in a collapsible panel below the chat header. The AI can also access your pinned notes as a tool.
  </Accordion>

  <Accordion title="Archive & Delete" icon="box-archive">
    Archive, delete, and label threads from the header or sidebar context menu with confirmation dialogs.
  </Accordion>

  <Accordion title="Unified Recent Chats" icon="clock-rotate-left">
    All chats now live under a chronological Recent Chats section with full context menu actions, replacing the separate Unfiled section.
  </Accordion>

  <Accordion title="Real-time Sidebar" icon="bolt">
    New chats, title changes, and completed responses appear instantly in the sidebar without page refresh.
  </Accordion>
</AccordionGroup>
