# v0.7.0 Release Notes

> v0.6.1 -> v0.7.0

## Summary

Renames the shared contract package so its identifier matches the library, a breaking change for every caller. Extends OpenRouter into a full multimodal provider covering image generation, speech-to-text, and text-to-speech, with model listings drawn from the vendor's own catalogs.

將共用契約套件更名，使識別字與函式庫名稱一致，所有呼叫端皆需調整。OpenRouter 擴充為完整多模態供應商，涵蓋圖片生成、語音轉文字與文字轉語音，模型清單改取自供應商自身目錄。

## ⚠️ Breaking Changes

### `package core` renamed to `package llmrouter`

The import path is unchanged; only the package identifier differs, so every unaliased `core.X` reference stops compiling.

**Before:**

```go
import "github.com/pardnchiu/go-llm-router/core"

var agent core.Agent
messages := []core.Message{{Role: "user", Content: "hi"}}
```

**After:**

```go
import llmrouter "github.com/pardnchiu/go-llm-router/core"

var agent llmrouter.Agent
messages := []llmrouter.Message{{Role: "user", Content: "hi"}}
```

**Migration:**

```go
// Option 1 — rename references (recommended)
// sed -i '' 's/\bcore\./llmrouter./g' on files importing .../core
import llmrouter "github.com/pardnchiu/go-llm-router/core"

// Option 2 — keep existing references with an explicit alias
import core "github.com/pardnchiu/go-llm-router/core"
```

<summary>翻譯</summary>

import 路徑不變，但套件識別字由 `core` 改為 `llmrouter`，所有未加別名的 `core.X` 引用都會編譯失敗。可將引用改寫為 `llmrouter.X`（建議），或在 import 加上 `core` 別名以維持既有寫法。
