</div>

This release fixes a critical issue where **compound components didn't work correctly in React Server Components (RSC)**. Additionally, this release adopts React 19 best practices by removing `forwardRef` and simplifying context usage. The Switch component has been refactored to match the Radio/RadioGroup pattern, providing a cleaner and more consistent API.

## What's New

### React Server Components Support

Compound components now work correctly in React Server Components. The previous implementation had the compound pattern logic inside components, which conflicted with the `"use client"` directive. This has been fixed by moving the pattern logic to component index files.

### React 19 Improvements

This release adopts React 19 best practices:

1. **Removed `forwardRef`**: No longer needed in React 19, where `ref` is now a prop ([React 19 docs](https://react.dev/blog/2024/12/05/react-19#ref-as-a-prop))
2. **Simplified Context**: `Context.Provider` replaced with just `Context` ([React 19 docs](https://react.dev/blog/2024/12/05/react-19#context-as-a-provider))

### Switch Component Architecture Improvement

The Switch component has been refactored to follow the same clean separation pattern as Radio/RadioGroup:

- **Separate Components**: Switch and SwitchGroup are now independent components (previously combined)
- **Cleaner API**: `<SwitchGroup>` replaces the nested `<Switch.Group>` and `<Switch.GroupItems>` pattern
- **Better Organization**: Separate styles, types, and implementations for each component
- **Consistent Pattern**: Matches the Radio/RadioGroup architecture for a more predictable API

**Before:**
```tsx
<Switch.Group>
  <Switch.GroupItems>
    <Switch.Root>...</Switch.Root>
  </Switch.GroupItems>
</Switch.Group>
```

**After:**
```tsx
<SwitchGroup>
  <Switch.Root>...</Switch.Root>
  <Switch.Root>...</Switch.Root>
</SwitchGroup>
```

## ⚠️ Breaking Changes

### Main Component Requires `.Root` Suffix

To support React Server Components, the compound component pattern has been restructured. The main component now requires the `.Root` suffix when using the compound pattern.

**Before:**
```tsx
import { Avatar } from "@heroui/react"

<Avatar>
  <Avatar.Image src="/images/avatar.jpeg" alt="Junior Garcia" />
  <Avatar.Fallback>JR</Avatar.Fallback>
</Avatar>
```

**After:**
```tsx
import { Avatar } from "@heroui/react"

<Avatar.Root>
  <Avatar.Image src="/images/avatar.jpeg" alt="Junior Garcia" />
  <Avatar.Fallback>JR</Avatar.Fallback>
</Avatar.Root>
```

**Note:** Named exports (e.g., `<Avatar>`, `<AvatarImage>`, `<AvatarFallback>`) remain unchanged and fully supported.

### Switch Component API Changes

The Switch component grouping API has been restructured to match the Radio/RadioGroup pattern:

**Before:**
```tsx
import { Switch } from "@heroui/react"

<Switch.Group orientation="horizontal">
  <Switch.GroupItems>
    <Switch.Root name="notifications">
      <Switch.Control>
        <Switch.Thumb />
      </Switch.Control>
      <Label>Notifications</Label>
    </Switch.Root>
    <Switch.Root name="marketing">
      <Switch.Control>
        <Switch.Thumb />
      </Switch.Control>
      <Label>Marketing</Label>
    </Switch.Root>
  </Switch.GroupItems>
</Switch.Group>
```

**After:**
```tsx
import { Switch, SwitchGroup } from "@heroui/react"

<SwitchGroup orientation="horizontal">
  <Switch.Root name="notifications">
    <Switch.Control>
      <Switch.Thumb />
    </Switch.Control>
    <Label>Notifications</Label>
  </Switch.Root>
  <Switch.Root name="marketing">
    <Switch.Control>
      <Switch.Thumb />
    </Switch.Control>
    <Label>Marketing</Label>
  </Switch.Root>
</SwitchGroup>
```

This change helps to:

- **Separate Components**: Switch and SwitchGroup are now independent components (previously combined)
- **Cleaner API**: `<SwitchGroup>` replaces the nested `<Switch.Group>` and `<Switch.GroupItems>` pattern
- **Better Organization**: Separate styles, types, and implementations for each component
- **Consistent Pattern**: Matches the Radio/RadioGroup architecture for a more predictable API


**Migration Steps:**
1. Import `SwitchGroup` separately: `import { Switch, SwitchGroup } from "@heroui/react"`
2. Replace `<Switch.Group>` with `<SwitchGroup>`
3. Remove the nested `<Switch.GroupItems>` wrapper
4. Individual `Switch.Root` components remain unchanged

#### Affected Components

All compound components are affected:

- `Accordion` → `Accordion.Root`
- `Avatar` → `Avatar.Root`
- `Card` → `Card.Root`
- `Disclosure` → `Disclosure.Root`
- `Fieldset` → `Fieldset.Root`
- `Kbd` → `Kbd.Root`
- `Link` → `Link.Root`
- `Popover` → `Popover.Root`
- `RadioGroup` → `RadioGroup.Root`
- `Switch` → `Switch.Root`
- `Tabs` → `Tabs.Root`
- `Tooltip` → `Tooltip.Root`

## Migration Guide

You have two options for using HeroUI compound components:

### Option 1: Update to Use `.Root` (Compound Pattern)

If you're using the compound pattern (dot notation), update your code to use `.Root` for the main component:

**Card Example:**
```tsx
import { Card } from "@heroui/react"

<Card.Root>
  <Card.Header>
    <Card.Title>Card Title</Card.Title>
    <Card.Description>Card description</Card.Description>
  </Card.Header>
  <Card.Content>
    Card content
  </Card.Content>
  <Card.Footer>
    Card footer
  </Card.Footer>
</Card.Root>
```

**Tabs Example:**
```tsx
import { Tabs } from "@heroui/react"

<Tabs.Root>
  <Tabs.ListWrapper>
    <Tabs.List>
      <Tabs.Tab id="tab1">Tab 1<Tabs.Indicator /></Tabs.Tab>
      <Tabs.Tab id="tab2">Tab 2<Tabs.Indicator /></Tabs.Tab>
    </Tabs.List>
  </Tabs.ListWrapper>
  <Tabs.Panel id="tab1">Panel 1</Tabs.Panel>
  <Tabs.Panel id="tab2">Panel 2</Tabs.Panel>
</Tabs.Root>
```

[See more examples in the documentation](/docs/components/card)

**Avatar Example:**
```tsx
import { Avatar } from "@heroui/react"

<Avatar.Root>
  <Avatar.Image alt="John Doe" src="..." />
  <Avatar.Fallback>JD</Avatar.Fallback>
</Avatar.Root>
```

[See more examples in the documentation](/docs/components/avatar)

### Option 2: Use Named Exports

We added support for named exports for all compound components. You can use them like this:

**Card Example:**
```tsx
import {
  CardRoot,
  CardHeader,
  CardTitle,
  CardDescription,
  CardContent,
  CardFooter,
} from "@heroui/react"

<CardRoot>
  <CardHeader>
    <CardTitle>Card Title</CardTitle>
    <CardDescription>Card description</CardDescription>
  </CardHeader>
  <CardContent>
    Card content
  </CardContent>
  <CardFooter>
    Card footer
  </CardFooter>
</CardRoot>
```

**Tabs Example:**
```tsx
import { TabsRoot, TabListContainer, TabList, Tab, TabIndicator, TabPanel } from "@heroui/react"

<TabsRoot>
  <TabListContainer>
    <TabList>
      <Tab id="tab1">Tab 1<TabIndicator /></Tab>
      <Tab id="tab2">Tab 2<TabIndicator /></Tab>
    </TabList>
  </TabListContainer>
  <TabPanel id="tab1">Panel 1</TabPanel>
  <TabPanel id="tab2">Panel 2</TabPanel>
</TabsRoot>
```

**Avatar Example:**
```tsx
import { Avatar, AvatarImage, AvatarFallback } from "@heroui/react"

<Avatar>
  <AvatarImage alt="John Doe" src="..." />
  <AvatarFallback>JD</AvatarFallback>
</Avatar>
```

### Migration Steps

If you're using the compound pattern, you only need to update the main component to use `.Root`:

1. **Find all instances of compound components** (e.g., `<Avatar>` with `<Avatar.Image>` inside)

2. **Add `.Root` to the main component**:
   ```tsx
   // Before
   <Avatar>
     <Avatar.Image ... />
   </Avatar>

   // After
   <Avatar.Root>
     <Avatar.Image ... />
   </Avatar.Root>
   ```

3. **That's it!** All child components (e.g., `Avatar.Image`, `Avatar.Fallback`) remain unchanged.

### Complete Migration Reference

| Component | Named Export Pattern | Compound Pattern (with `.Root`) | Additional Changes |
|-----------|---------------------|---------------------|---------------------|
| **Accordion** | `<Accordion>` | `<Accordion.Root>` | - |
| **Avatar** | `<Avatar>` | `<Avatar.Root>` | - |
| **Card** | `<Card>` | `<Card.Root>` | - |
| **Disclosure** | `<Disclosure>`  | `<Disclosure.Root>`  | - |
| **Fieldset** | `<Fieldset>`  | `<Fieldset.Root>` | - |
| **Kbd** | `<Kbd>` | `<Kbd.Root>`  | - |
| **Link** | `<Link>` | `<Link.Root>` | - |
| **Popover** | `<Popover>` | `<Popover.Root>` | - |
| **Radio** |  `<Radio>` | `<Radio.Root>` | - |
| **Switch** | `<Switch>`, `<SwitchControl>` | `<Switch.Root>`, `<Switch.Control>` | `<Switch.Group>` → `<SwitchGroup>` (separate component) |
| **Tabs** | `<Tabs>`, `<TabList>` | `<Tabs.Root>`, `<Tabs.List>` | - |
| **Tooltip** | `<Tooltip>`, `<TooltipTrigger>` | `<Tooltip.Root>`, `<Tooltip.Trigger>` | - |

### Automated Migration

For large codebases using the compound pattern, you can use find-and-replace:

```bash
# Example for Avatar component
# Update the main component to use .Root
sed -i 's/<Avatar>/<Avatar.Root>/g' **/*.tsx
sed -i 's/<\/Avatar>/<\/Avatar.Root>/g' **/*.tsx

# Switch component requires additional steps
# First, ensure SwitchGroup is imported
# Then replace Switch.Group with SwitchGroup
sed -i 's/<Switch\.Group/<SwitchGroup/g' **/*.tsx
sed -i 's/<\/Switch\.Group>/<\/SwitchGroup>/g' **/*.tsx

# Remove Switch.GroupItems wrapper
sed -i 's/<Switch\.GroupItems>//g' **/*.tsx
sed -i 's/<\/Switch\.GroupItems>//g' **/*.tsx

# Repeat for other compound components (Card, Tabs, etc.)
# Note: This only affects files using the compound pattern
```

**Important:**
- Be careful with automated replacements. Make sure you're only replacing compound pattern usage, not named exports.
- For Switch migrations, verify that `SwitchGroup` is imported: `import { Switch, SwitchGroup } from "@heroui/react"`
- Test your code after running automated migrations to ensure all changes are correct.

## Why This Change?

This change was necessary to fix React Server Components compatibility. The previous implementation had architectural limitations:

1. **RSC Compatibility**: Compound pattern logic conflicted with `"use client"` directives
2. **React 19 Readiness**: Removes deprecated patterns like `forwardRef` and `Context.Provider`
3. **Cleaner Architecture**: Pattern logic is now in index files, not component files
4. **Better Separation**: Server and client components can now work together seamlessly

## Documentation Updates

Component documentation will be updated to reflect the new patterns:

- Examples will show the compound pattern with `.Root`
- Named export examples remain valid and supported
- Migration guides will help you transition smoothly
- Both patterns are fully supported and work identically

## Need Help?

If you encounter any issues during migration:

1. **Compound pattern users**: Update the main component to use `.Root` (e.g., `<Avatar>` → `<Avatar.Root>`)
2. **Named export users**: No changes needed - your code continues to work as-is
3. Check the component documentation for examples
