 ## Run the Windows release
 
-1. Open [GitHub Releases](https://github.com/breeze0305/UFriend/releases) and download **UFriend-0.1.39-Portable.exe** for Windows x64. GitHub's **Source code** archives are not runnable desktop packages.
+1. Open [GitHub Releases](https://github.com/breeze0305/UFriend/releases) and download **UFriend-0.1.41-Portable-WithFFmpeg.exe** for Windows x64. Source archives and the separate FFmpeg developer package are not needed to run UFriend.
 2. Save the EXE in a folder you want to keep. If another version is running, quit it from the system tray menu first.
 3. Double-click the downloaded EXE. No installation wizard, Node.js, or manual extraction is needed.
 4. For English, open **設定 → 一般 → 軟體介面語言**, choose **English**, and save.
 
 The launcher extracts the application into a separate temporary directory for each run. Workspace data and encrypted credentials remain in your Windows user data directory; they are not stored inside the downloaded EXE or its temporary extraction folder. Restarting from the system tray launches the original portable EXE. Keep that file in place until you fully quit the app.
 
-**Optional media runtime:** the public EXE contains no FFmpeg executable, AI models, or shared OAuth client. For captioned-video export or cloud speech transcription, open **Settings → General → Media runtime**:
+**Included media runtime:** the `WithFFmpeg` EXE includes FFmpeg for captioned-video export and audio preparation for cloud speech transcription. No separate FFmpeg installation or 7-Zip is needed. **Settings → General → Media runtime** shows that the runtime is included. The release also provides its complete corresponding source, dependency sources, and build scripts as a separate download.
+
+Older releases and builds made without FFmpeg provide these optional installation controls instead:
 
 - **Download and install media runtime** downloads the pinned build from Gyan and verifies its hashes. An existing 7-Zip installation is required.
 - **Select extracted package** opens a folder picker for an already extracted official package. It does not download anything or require 7-Zip.
 - **Media runtime instructions** opens the [runtime guide](docs/development/FFMPEG_RUNTIME.md).
 
 A runtime installed through the app is saved in your user data directory and remains available after restarting or replacing the portable EXE. Local Whisper uses its own independently installed runtime. AI model services and Gmail still require the separate configuration described below.
 
-If you use a folder-based ZIP package instead, extract the **entire ZIP**, keep its DLLs, resources, and license files together, and run its `UFriend.exe`. The ZIP also includes `Install media runtime.cmd`; the runtime guide covers that alternative.

 This uses the pinned electron-builder 26.17.0 NSIS portable target. The first build needs network access to download its build tools.

 - **Electron and Chromium**: folder packages retain Electron's `LICENSE` and `LICENSES.chromium.html` beside the application executable. The single-file portable EXE contains that application payload and expands it, including the notices, into its temporary run directory.
 - **npm dependencies**: exact versions and declared licenses are recorded in `package-lock.json`. Production dependency license files are retained under `resources/app/node_modules` in the application payload.
 - **Portable build tooling**: the single-file EXE is generated using the pinned electron-builder 26.17.0 NSIS portable target. Build dependencies are identified in the lockfile and retain their own licenses; they are separate from UFriend's project license.
-- **FFmpeg**: the public portable EXE and the ZIP built with `--without-ffmpeg` do not include an FFmpeg binary. The optional installer downloads the pinned Gyan build directly from its publisher, or accepts an extracted official package selected by the user. That build is GPLv3. Its license, upstream notices, and provenance are provided in `scripts/runtime/ffmpeg` and retained beside the installed executable. An installation through Settings is stored in the Windows user data directory and survives application restarts and updates. The optional local `--with-ffmpeg` build instead embeds the verified executable together with those notices. Before distributing that GPL-containing build, provide its complete corresponding source, including required external-library sources and build scripts; the provenance links alone are not such a source bundle. See [FFmpeg runtime documentation](docs/development/FFMPEG_RUNTIME.md).
+- **Bundled FFmpeg**: the `Portable-WithFFmpeg.exe` release embeds a UFriend build of FFmpeg as a separate executable. It enables GPL components, including x264, and is provided under GPLv3. The executable is accompanied by the GPL text, `THIRD_PARTY_LICENSES.txt`, and source/build information from `scripts/runtime/ffmpeg-bundled`. The matching complete source archive, including the linked dependency sources and build scripts, is distributed beside the EXE on its GitHub Release. Its exact hash is recorded in the bundled runtime manifest. These terms do not relicense UFriend's independent MIT code.
+- **Optional FFmpeg**: builds made without FFmpeg retain the optional installer, which downloads the pinned Gyan GPLv3 build directly from its publisher or accepts the user's extracted official package. Its distinct notices and manifest remain in `scripts/runtime/ffmpeg`. This path does not redistribute the Gyan executable. Installations through Settings remain in the Windows user data directory across app updates. See [FFmpeg runtime documentation](docs/development/FFMPEG_RUNTIME.md).
 
 Redistribution of third-party binaries must comply with their own terms. The UFriend license does not replace or relicense those components.
