# v0.3.1 Release Notes

> v0.3.0 -> v0.3.1

## Summary

Brings Discord's interactive surface to parity with Telegram in Discord-native ways: `SendInput` mounts a Primary Button → Modal flow (Discord's only path to free-text capture from a message context), `SendSelect` and `SendMultiSelect` use String Select Menu dropdowns (`MaxValues=1` and `MaxValues=N` — Discord supports multi-pick natively so the telegram ✅/⬜ toggle + "Done" button machinery isn't needed), `SendVoice` uploads Gemini TTS output as an `audio/ogg` attachment, and `Delete` is added as a thin `ChannelMessageDelete` wrapper for Q&A prompt cleanup. `Input` gains `CallbackPicks []string` so multi-select results land on a dedicated field instead of overloading `Text`.

把 Discord 的互動 surface 補齊到對齊 telegram、且走 Discord 原生路徑：`SendInput` 用 Primary Button → Modal 流程（Discord 從 MessageCreate context 抓自由文字輸入的唯一路徑）；`SendSelect` 與 `SendMultiSelect` 走 String Select Menu dropdown（`MaxValues=1` / `MaxValues=N`，Discord 原生支援多選，不需 telegram 那套 ✅/⬜ + Done button 中介）；`SendVoice` 把 Gemini TTS OGG 上傳為 `audio/ogg` 附件；新增 `Delete` 薄封裝 `ChannelMessageDelete` 用於 Q&A prompt 清場。`Input` 新增 `CallbackPicks []string`，多選結果走專屬欄位不擠在 `Text`。
