# v0.28.1 Release Notes

> v0.28.0 -> v0.28.1

## Summary

Fixes a Gemini `generateContent` HTTP 400 by stripping JSON Schema meta keywords (`$schema`, `$ref`, `additionalProperties`, …) that its Schema proto rejects. Surfaces subagent streamed text to the parent event channel and reorders multiplexed SSE subscription to avoid initial-event loss. Adds a `reasoning_content` field to the message type and removes the `worker/` directory.

修正 Gemini `generateContent` HTTP 400：剝除其 Schema proto 不接受的 JSON Schema meta 關鍵字（`$schema`、`$ref`、`additionalProperties` 等）。將 subagent 串流文字轉發至 parent event channel，並調整多工 SSE 訂閱順序以避免初始事件遺失。訊息型別新增 `reasoning_content` 欄位，並移除 `worker/` 目錄。

### FIX
- Strip unsupported JSON Schema keywords (`$schema`, `$ref`, `$defs`, `additionalProperties`, …) from Gemini tool params to prevent `generateContent` HTTP 400 (@pardnchiu) [0a2d191]
- Forward subagent `EventText`/`EventTextDone` to parent so streamed text is no longer dropped (@pardnchiu) [de37b60]
- Reorder multiplexed SSE subscription to after the connected-event flush to prevent initial event loss; suppress duplicate agent-result line in TUI render (@pardnchiu) [de37b60]
