## Latest version
To update to the latest version of Next.js, you can use the `upgrade` command:
```bash package="pnpm"
pnpm next upgrade
```
```bash package="npm"
npx next upgrade
```
```bash package="yarn"
yarn next upgrade
```
```bash package="bun"
bunx next upgrade
```
Versions before Next.js 16.1.0 do not support the `upgrade` command and need to use a separate package instead:
```bash filename="Terminal"
npx @next/codemod@canary upgrade latest
```
If you prefer to upgrade manually, install the latest Next.js and React versions:
```bash package="pnpm"
pnpm i next@latest react@latest react-dom@latest eslint-config-next@latest
```
```bash package="npm"
npm i next@latest react@latest react-dom@latest eslint-config-next@latest
```
```bash package="yarn"
yarn add next@latest react@latest react-dom@latest eslint-config-next@latest
```
```bash package="bun"
bun add next@latest react@latest react-dom@latest eslint-config-next@latest
```
## Canary version
To update to the latest canary, make sure you're on the latest version of Next.js and everything is working as expected. Then, run the following command:
```bash package="pnpm"
pnpm add next@canary
```
```bash package="npm"
npm i next@canary
```
```bash package="yarn"
yarn add next@canary
```
```bash package="bun"
bun add next@canary
```
