[中文](#cn-v0.1.3-alpha.1) | [English](#en-v0.1.3-alpha.1)
<h3 id="cn-v0.1.3-alpha.1">新增功能</h3>
* Web 支持上传任意类型的通用文件：文件与图片可在同一预览区混排，后台上传支持进度、取消与会话切换续显，模型可通过已保存路径使用现有文件工具按需读取。 @CreatixChu
* 所有出站网络请求都会遵循启动环境中的 `HTTP_PROXY`、`HTTPS_PROXY`、`ALL_PROXY` 与 `NO_PROXY` 配置。 @LegGasai
* Python SDK 新增 macOS x64 runtime wheel，可在 Intel 架构的 Mac 上安装并运行随包 runtime。 @koalazf99
* `read_image` 的顶层与 PTC 嵌套工具调用会在 Web 工具卡中直接渲染图片，不再展示原始附件对象。 @Chinesezjc
* 模型探测新增对自定义模型提供商 `models` 对象和 Anthropic 原生模型列表的支持，并支持回填模型名称、上下文窗口及最大输出 token 的回填。 @LegGasai
<h3>问题修复</h3>
* 在 Web 中手动暂停目标会立即终止当前模型轮次，避免运行中的模型继续执行或在同一轮恢复目标。 @mektpoy
* 修复 DeepSeek 流式工具调用的续传分片用空值覆盖调用 ID 或名称的问题，避免工具以空名称失败并写入无法重新打开的会话记录。 @LegGasai
* 修复 Python SDK 单文件 runtime 将 Bash 中以 `node` 开头的命令错误重写为 dsh runtime 的问题。 @imccyu
* 修复从会话搜索结果进入会话后仍停留在搜索界面的问题；目标会话会在所属 Workspace 中展开并滚动到可见位置。 @Dudu-0223
* 修复 Windows 盘符根目录 Workspace 的路径分隔符、标题与绝对路径校验，确保盘符根目录可以正常使用。 @turtle1999
* 修复 Session 缓存读取问题。 @imccyu
<h3>体验优化</h3>
* Skill 选择器支持模糊搜索；优化聊天气泡中的的 Skill 和命令引用。 @LegGasai
* 统一会话内可点击链接的颜色、hover/focus 样式和分类图标，优化 Markdown 链接、文件引用、网页来源、产物链接与 Workflow 成员链接的辨识度。 @yixiangihsiang
* 统一未观察文件写入与编辑失败的 `FS_NOT_OBSERVED` 诊断，保留文件路径、结构化错误码和原始原因。 @turtle1999
* Windows 上的本地非终端子进程不再弹出控制台窗口。 @turtle1999
* Agent Team 的 `send_message` 统一采用 steer 语义，并在跨 Agent 和冷恢复投递中保留发送者归属与顺序。 @Dudu-0223
<h3>其他变更</h3>
* **破坏性变更：**Session persistence API 改为由生命周期持有的 `SessionHandle`；`agentLoop.create()` 改为异步，新增session锁，同一session至多被一个进程持有。 @turtle1999
* Session format 升级至 v2：旧 v0/v1 日志通过不可变的相邻 generation 迁移到当前格式，Assistant 流按 attempt 聚合进持久化 settlement，同时 Web 保持实时增量显示。 @tianyicui
* 已知的性能缺陷：本版本存在一项已知的性能回退，可能影响部分历史session加载的响应速度；我们将在下一个版本中修复。

<h3 id="en-v0.1.3-alpha.1">New Features</h3>
* Web now supports uploads of arbitrary file types: files and images share a preview area, background uploads expose progress and cancellation and remain visible across conversation switches, and models can use existing file tools to read saved paths on demand. by @CreatixChu
* All outbound network requests honor the `HTTP_PROXY`, `HTTPS_PROXY`, `ALL_PROXY`, and `NO_PROXY` settings from the startup environment. by @LegGasai
* The Python SDK adds a macOS x64 runtime wheel, allowing Intel-based Macs to install and run the bundled runtime. by @koalazf99
* Render images directly in Web tool cards for top-level and PTC-nested `read_image` calls instead of showing raw attachment objects. by @Chinesezjc
* Model discovery now supports `models` objects from custom model providers and native Anthropic model lists, and fills in model names, context windows, and maximum output tokens when needed. by @LegGasai
<h3>Bug Fixes</h3>
* Immediately abort the active model turn when a goal is paused manually in Web, preventing the running model from continuing or resuming within the same turn. by @mektpoy
* Preserve tool-call IDs and names across DeepSeek streaming continuation chunks, preventing empty tool names and conversation records that cannot be reopened. by @LegGasai
* Prevent the Python SDK single-file runtime from rewriting Bash commands that begin with `node` as dsh runtime invocations. by @imccyu
* Open a conversation selected from search in its Workspace, expand it, and scroll it into view instead of leaving the search interface open. by @Dudu-0223
* Fix path separators, titles, and absolute-path validation for Windows drive-root Workspaces so drive roots work correctly. by @turtle1999
* Fix Session cache reads. by @imccyu
<h3>Improvements</h3>
* The Skill picker supports fuzzy search, with improved Skill and command references in chat bubbles. by @LegGasai
* Unify colors, hover and focus states, and category icons for clickable conversation links, making Markdown links, file references, web sources, artifact links, and Workflow member links easier to distinguish. by @yixiangihsiang
* Standardize `FS_NOT_OBSERVED` diagnostics for unobserved file writes and failed edits while preserving the file path, structured error code, and original cause. by @turtle1999
* Prevent local non-terminal subprocesses from opening console windows on Windows. by @turtle1999
* Agent Team `send_message` consistently uses steer semantics and preserves sender attribution and ordering across agents and cold recovery. by @Dudu-0223
<h3>Chores</h3>
* **Breaking change:** The Session persistence API is now owned by lifecycle-scoped `SessionHandle`s; `agentLoop.create()` is asynchronous, and a new Session lock ensures that each Session is held by at most one process. by @turtle1999
* Upgrade the Session format to v2: immutable adjacent-generation migrations convert v0/v1 logs to the current format, Assistant streams are aggregated by attempt into durable settlements, and Web preserves real-time incremental rendering. by @tianyicui
* This release has a known performance regression that may affect responsiveness in some scenarios. We will address it in the next release.
