中文

Diagramon 3.13.1 是一个小版本：把 Mermaid 提到格式清单的第一位，其余只是内部修复。

下载

方式 文件 说明
安装版（推荐） Diagramon_3.13.1_x64-setup.exe（约 62.29 MiB） 装完可用内置自动更新；缺 WebView2 时安装器会自动下载运行时
便携版（免安装） Diagramon-3.13.1-win-x64.zip（约 70.40 MB） 解压到任意位置，双击 diagramon.exe 即用；卸载 = 删文件夹

便携版说明：包里是 diagramon.exe + WebView2Loader.dll + ui\ + assets\，必须放在一起
（ui\ 与 assets\ 是从磁盘读的，不在 exe 里）。它不依赖额外要装的东西：不需要 Node.js、
不需要 Chrome、不需要 VC++ 运行库（exe 已静态链接 CRT），只需要 Windows 10/11 自带的 WebView2 运行时。
便携版的「检查更新」照常能发现新版，但更新走的是安装包（不会就地替换便携目录）——
要继续用便携形态，就手动下载新的 ZIP 覆盖。

本次亮点

  • 新建时 Mermaid 排第一：Ctrl+N / 标签条 ＋ / 文件 → 新建 里的格式卡片，
    第一张就是 Mermaid。顺序对四处同时生效 —— 新建对话框、标签条「转换」下拉、
    「转换能力一览」的方向清单与矩阵 —— 因为它们读的是同一份格式注册表，
    不存在"这里改了那里没改"。
  • 新顺序：Mermaid → drawio → Excalidraw → DOT → D2（原先 drawio 在第一位）。

修复

  • 内部：修掉一条会偶发失败的验收探针（画布「事件归属」那组断言等的是 120ms 轮询，
    在机器忙的时候会被计时器节流骗到）。用户无感，但我们的门禁从此不再时红时绿。
  • 内部：浏览器原型的格式清单同步成同一顺序（它没有 Rust 后端，只能抄一份，
    这次两边的顺序不一致就是靠新加的断言发现的）。

关于 Diagramon

Diagramon 是一款本地优先的多格式图表编辑器：Mermaid / Graphviz DOT / drawio / Excalidraw
都可编辑并实时预览，AI 可辅助生成、评审与识图。渲染与校验不联网也能用 ——
只有你主动使用 AI 时，相关代码或图片才会发往你选择的上游。

系统要求

  • Windows 10 / 11 64 位
  • WebView2 运行时（Windows 10/11 通常已预装；缺失时安装器会现场下载）
  • 不需要 Node.js、Chrome 或 VC++ 运行库 —— 画布运行时与前端资源都随包分发

安装与更新

下载 Diagramon_3.13.1_x64-setup.exe 直接安装。已装旧版的用户可在
帮助 → 检查更新 里收到本版本（更新包即本安装包，签名见 latest.json）。

本安装包尚未做 Authenticode 代码签名，Windows SmartScreen 可能给出提示。

English

Diagramon 3.13.1 is a small release: Mermaid moves to the top of the format list; the rest is
internal cleanup.

Downloads

Type File Notes
Installer (recommended) Diagramon_3.13.1_x64-setup.exe (~62.29 MiB) Enables the built-in auto-update; if WebView2 is missing the installer downloads the runtime
Portable (no install) Diagramon-3.13.1-win-x64.zip (~70.40 MB) Unzip anywhere and run diagramon.exe; uninstall = delete the folder

About the portable build: it ships diagramon.exe + WebView2Loader.dll + ui\ + assets\, and those
must stay together (the ui\ and assets\ trees are read from disk, not embedded in the exe).
It needs nothing extra installed: no Node.js, no Chrome, no VC++ redistributable (the CRT is
statically linked) — only the system WebView2 runtime that comes with Windows 10/11.
"Check for updates" still finds new versions, but updating downloads the installer
(it does not replace the portable folder in place) — to stay portable, grab the new ZIP manually.

Highlights

  • Mermaid is first when creating a document: in the Ctrl+N / tab + / File → New chooser, the
    first card is Mermaid. The order applies to four places at once — the New dialog, the tab strip's
    "Convert" menu, and both the direction list and the matrix of "Conversion capabilities" — because they
    all read the same format registry, so there is no "changed here, not there".
  • New order: Mermaid → drawio → Excalidraw → DOT → D2 (drawio used to be first).

Fixes

  • Internal: fixed an intermittently failing acceptance probe (the canvas "event ownership" assertions
    waited on a 120 ms poll and could be fooled by timer throttling on a busy machine). Invisible to users,
    but our gate no longer goes red at random.
  • Internal: the browser prototype's format list now matches the same order (it has no Rust backend and has
    to keep a copy; the two lists differing is exactly what the new assertion caught).

About Diagramon

Diagramon is a local-first multi-format diagram editor: Mermaid, Graphviz DOT, drawio and Excalidraw
can all be edited with live preview, with AI assistance for generation, review and image recognition.
Rendering and validation work with no network at all — code or images reach a model only when you
actively use AI, and then only the endpoint you chose.

Requirements

  • Windows 10 / 11 64-bit
  • WebView2 runtime (normally pre-installed on Windows 10/11; the installer downloads it if missing)
  • No Node.js, Chrome or VC++ redistributable needed — the canvas runtimes and front-end assets all
    ship inside the installer

Install and update

Download Diagramon_3.13.1_x64-setup.exe and run it. Users on an older version
get this release through Help → Check for updates (the update package is this installer; the signature
is in latest.json).

The installer is not yet Authenticode-signed, so Windows SmartScreen may show a prompt.
