sidebarTitle: Upgrade Bun

Bun upgrades itself with the built-in `bun upgrade` command.
```bash terminal icon="terminal"
bun upgrade
```
`bun upgrade` downloads and installs the latest stable version of Bun, replacing the currently installed version. If you're on a canary build, `bun upgrade` installs the latest canary build instead.
<Note>To see the current version of Bun, run `bun --version`.</Note>
---
## Verify the upgrade
After upgrading, verify the new version:
```bash terminal icon="terminal"
bun --version
# Output: 1.x.y
# See the exact commit of the Bun binary
bun --revision
# Output: 1.x.y+abc123def
```

## Upgrade to canary builds
Canary builds are published automatically from the `main` branch once a commit's CI tests pass. They're useful for trying new features or verifying bug fixes before a release.
```bash terminal icon="terminal"
bun upgrade --canary
```
<Warning>Canary builds are not recommended for production use. They may contain bugs or breaking changes.</Warning>
---
## Switch back to stable
If you're on a canary build and want to return to the latest stable release:
```bash terminal icon="terminal"
bun upgrade --stable
```
---
## Install a specific version
To install a specific version of Bun, use the install script with a version tag:
<Tabs>
<Tab title="macOS & Linux">
```bash terminal icon="terminal"
curl -fsSL https://bun.sh/install | bash -s "bun-v1.3.3"
```
</Tab>
<Tab title="Windows">
```powershell PowerShell icon="windows"
iex "& {$(irm https://bun.sh/install.ps1)} -Version 1.3.3"
```
</Tab>
</Tabs>

## Package manager users
If you installed Bun with a package manager, upgrade with that package manager instead of `bun upgrade` to avoid conflicts.
<Tip>
**Homebrew users** <br />
Use `brew upgrade bun` instead.
**Scoop users** <br />
Use `scoop update bun` instead.
</Tip>
