# core release

Build and publish releases to GitHub, npm, Homebrew, Scoop, AUR, Chocolatey, Docker, and LinuxKit.

## Usage

```bash
core release [flags]
```

## Flags

| Flag | Description |
|------|-------------|
| `--dry-run` | Preview what would be published |
| `--version` | Override version (default: git tag) |
| `--target` | Release target: `sdk` for SDK-only release |
| `--draft` | Create release as draft |
| `--prerelease` | Mark release as prerelease |

## Quick Start

```bash
# Initialize release config
core release init

# Preview release
core release --dry-run

# Release
core release

# SDK-only release
core release --target sdk
```

## SDK Release

Generate SDKs without building binaries:

```bash
# Generate SDKs with version from git tag
core release --target sdk

# Explicit version
core release --target sdk --version v1.2.3

# Preview
core release --target sdk --dry-run
```

This will:
1. Determine version from git tags (or `--version` flag)
2. Run breaking change detection if configured
3. Generate SDKs for all configured languages
4. Output to `sdk/` directory

See [SDK commands](sdk.md) for more details.
