## Release 39.0.0

This release adds Tailwind CSS v4 integration via
`@metamask/design-tokens/tailwind/theme.css`, ships extension migration
UI on React web (`Modal`, `ModalContent`, `Skeleton`, `HeaderBase`),
adds Tailwind preset animations (`animate-slide-up`,
`animate-skeleton-pulse`), and refreshes the shared icon set
(`ListArrow`, `Musd`, `MusdFilled`, `Group`, `PieChart`, `Predictions`,
refreshed `Candlestick`, `Musd` SVG fix) across
`@metamask/design-system-shared`, React, and React Native. **React
Native** also ships a **breaking** Toast follow-up
([#1143](#1143)):
root **`Toaster`**, imperative **`toast`** / **`toast.dismiss()`**, and
flat **`ToastSeverity`** options. The TWRNC preset widens its React peer
range for newer React Native / React stacks.

### 📦 Package Versions

- `@metamask/design-tokens`: **8.4.0**
- `@metamask/design-system-shared`: **0.17.0**
- `@metamask/design-system-react`: **0.22.0**
- `@metamask/design-system-react-native`: **0.24.0**
- `@metamask/design-system-tailwind-preset`: **0.8.0**
- `@metamask/design-system-twrnc-preset`: **0.4.2**

### 🎨 Design Tokens (8.4.0)

#### Added (#1117)

**What changed**

- Added `@metamask/design-tokens/tailwind/theme.css` for Tailwind CSS v4
so consumers can import MetaMask token variables, theme values,
typography, font, and shadow utilities in one place.

**Impact**

- Web apps on Tailwind v4 can adopt the token theme without hand-rolling
CSS variables; see [Tailwind CSS v3 to
v4](./packages/design-tokens/MIGRATION.md#tailwind-css-v3-to-v4).

### 🪶 `@metamask/design-system-tailwind-preset` (0.8.0)

#### Added

- **`animate-slide-up`** (and `slide-up` keyframes) for the same dialog
entrance motion as `ModalContent`
([#1139](#1139))
- **`animate-skeleton-pulse`** (and `skeleton-pulse` keyframes) for
loading placeholders used with `Skeleton`
([#1146](#1146))

### 📲 `@metamask/design-system-twrnc-preset` (0.4.2)

#### Changed (#844)

- Expanded the `react` peer dependency range to `>=18.2.0` so the preset
installs cleanly alongside React Native 0.76 and React 19 app stacks.

### 🔄 Shared Type Updates (0.17.0)

#### Shared icon set (#1157, #1161, #1162, #1163)

**What changed**

- Extended the shared icon set with `ListArrow`, `Musd`, `MusdFilled`,
`Group`, `PieChart`, and `Predictions`, refreshed the `Candlestick`
icon, and corrected the `Musd` asset to use a single SVG path.

**Impact**

- Keeps `IconName` and assets aligned for
`@metamask/design-system-react` and
`@metamask/design-system-react-native`.

### 🌐 React Web Updates (0.22.0)

#### Added

- Added `Modal` and `ModalContent` for dialogs, `Skeleton` for loading
placeholders, and `HeaderBase` for header layouts—supporting the
MetaMask extension migration into the design system
([#1136](#1136),
[#1139](#1139),
[#1146](#1146),
[#1142](#1142))
- Added icons `ListArrow`, `Musd`, `MusdFilled`, `Group`, `PieChart`,
and `Predictions`, and updated the `Candlestick` icon
([#1157](#1157),
[#1161](#1161),
[#1162](#1162))

#### Fixed

- Corrected the `Musd` icon asset so it renders from a single SVG path
([#1163](#1163))

### 📱 React Native Updates (0.24.0)

#### Added

- Added icons `ListArrow`, `Musd`, `MusdFilled`, `Group`, `PieChart`,
and `Predictions`, and updated the `Candlestick` icon
([#1157](#1157),
[#1161](#1161),
[#1162](#1162))

#### Changed

- **BREAKING:** Toast API follow-up
([#1143](#1143)):
mount **`<Toaster />`** once at the root; use **`toast(...)`** /
**`toast.dismiss()`** instead of **`Toast.show(...)`** /
**`Toast.hide()`**; content-first options with **`ToastSeverity`** and
**`iconAlertProps`** (renamed from **`iconProps`**). See [Migration
Guide](./packages/design-system-react-native/MIGRATION.md#from-version-0230-to-0240).

#### Fixed

- Corrected the `Musd` icon asset so it renders from a single SVG path
([#1163](#1163))

### ⚠️ Breaking Changes

#### React Native — Toast (#1143)

**What changed**

- Imperative API moves from **`Toast.show`** / **`Toast.hide`** on
**0.23.x** to **`toast`** / **`toast.dismiss()`** with a root
**`<Toaster />`**.
- Options flatten to **`title`**, **`description`**, **`severity`**
(**`ToastSeverity`**), accessories, and **`iconAlertProps`**; map
**`ToastVariant`**-style payloads from **0.23.0** using the migration
guide.

**Migration**

- See [From version 0.23.0 to
0.24.0](./packages/design-system-react-native/MIGRATION.md#from-version-0230-to-0240)
(and [Toast
Component](./packages/design-system-react-native/MIGRATION.md#toast-component)
for component-library migration context).

downstream installs. React Native release notes include a breaking
`Toast` API change that consumers must account for when upgrading.
> 
> **Overview**
> Bumps the monorepo release to `39.0.0` and increments package versions
for `@metamask/design-system-react` (`0.22.0`),
`@metamask/design-system-react-native` (`0.24.0`),
`@metamask/design-system-shared` (`0.17.0`), and
`@metamask/design-system-tailwind-preset` (`0.8.0`), updating
corresponding changelogs and compare links.
>

`@metamask/design-system-tailwind-preset@^0.8.0` (and aligns
`yarn.lock`). Changelogs capture the release contents, including new
modal/skeleton/header additions on web, icon set updates across
