## Unreleased
+## v1.4.9 - 2026-05-07
+
+- Added Remote-mode image routing: image requests now use the proven Lingma IPC image pipeline instead of sending local/data URLs directly to the remote chat endpoint.
+- Added mixed image + tool handling: the proxy extracts image context through IPC, then returns to Remote API native tool calling so clients still receive proper `tool_calls` / `tool_use`.
+- Fixed multi-turn image follow-ups by reusing the most recent user image from request history when the latest user turn says things like "continue based on the previous image".
+- Improved Remote API tool compatibility by forwarding structured messages, tool definitions, tool choice, and native remote tool-call deltas instead of prompt-emulating tools in Remote mode.
+- Added regression tests for remote structured tools, image routing, image-context injection, and previous-turn image reuse.
+- Verified the production desktop app launch path from `/Applications/Lingma Proxy.app`, including pure image, multi-turn image, and image + forced tool-call requests.
+
## v1.4.8 - 2026-05-06
- Fixed Remote API base URL auto-detection so Lingma OSS/static asset hosts are rejected and cannot be used as API endpoints.

@@ -90,6 +90,7 @@ Compared with the original protocol proof of concept, this repository focuses on
- **Anthropic streaming tool-call hardening** so streaming clients such as Claude Code receive final `tool_use` events instead of premature refusal text when tools are present.
- **Image input** for OpenAI `image_url` and Anthropic image blocks.
- **Local and remote image normalization** for data URLs, HTTP URLs, `file://` URLs, and absolute local paths, with automatic JPEG downscaling for large images.
+- **Remote-mode image fallback** so image requests use the proven Lingma IPC image pipeline; image + tool requests extract image context through IPC and then return to Remote API native tool calling.
- **Request log image redaction** so large base64 payloads are visible as image markers instead of breaking the desktop log view.
- **More request parameter compatibility** so stricter clients can connect without custom patches.
- **Full request and response recording** in the desktop app for debugging 400/500 errors.

@@ -221,6 +225,7 @@ Notes:
- If your Lingma plugin uses a dedicated domain, remote mode first uses `--remote-base-url`, `LINGMA_REMOTE_BASE_URL`, or the JSON config field. If those are empty, it scans Lingma's local logs on macOS, Windows, and Linux for endpoint hints such as `endpoint config:` and marketplace service URLs.
- The desktop Settings page shows the resolved remote domain and detection source without exposing tokens.
- `/v1/models` in remote mode returns remote API model keys, which may not match the IPC plugin display IDs such as `MiniMax-M2.7` or `Kimi-K2.6`.
+- Image requests in remote mode are routed through the IPC image pipeline because the direct remote chat endpoint ignores local `file://` and data URL image payloads. If a request also contains tools, Lingma Proxy first extracts image context through IPC and then sends the tool-capable turn through Remote API native tool calling.
- Local validation passed `/health`, `/v1/models`, OpenAI streaming/non-streaming chat, and Claude Code Anthropic + Bash tool use. Claude Code full tool runs are much slower than simple OpenAI requests because the client sends a large context and performs a second tool-result turn.
- This mode is inspired by the remote API and credential-signing research in [ZipperCode/lingma2api](https://github.com/ZipperCode/lingma2api), integrated here as a switchable backend under the existing OpenAI / Anthropic / desktop app architecture.

- 如果 Lingma 插件配置过专属域名,远端模式会优先使用 `--remote-base-url`、`LINGMA_REMOTE_BASE_URL` 或配置文件;这些为空时,会扫描 macOS、Windows、Linux 上 Lingma 本地日志里的 `endpoint config:`、Marketplace service URL 等线索。
- 桌面端设置页会展示当前解析到的远端域名和来源,但不会展示 token / key 明文。
- 远端模式的 `/v1/models` 返回的是远端接口模型 key,不一定等同于 IPC 插件模式里看到的 `MiniMax-M2.7`、`Kimi-K2.6` 等展示名。
+- 远端模式下的图片请求会自动走 IPC 图片链路,因为直连远端聊天接口不会直接消费本地 `file://` 和 data URL 图片。若请求同时带工具,代理会先通过 IPC 提取图片上下文,再把不含图片但包含上下文的请求交给 Remote API 原生工具调用。
- 当前本机实测:`/health`、`/v1/models`、OpenAI 流式 / 非流式、Claude Code Anthropic + Bash 工具调用均可用;Claude Code 完整工具链耗时明显高于简单 OpenAI 请求。
- 该模式参考了 [ZipperCode/lingma2api](https://github.com/ZipperCode/lingma2api) 对 Lingma 远端接口、签名和登录态结构的探索,本仓库将其作为可切换后端集成到现有 OpenAI / Anthropic / 桌面 App 架构中。
