This preview fixes the two things that directly affected upgrading and downloading. A stable build switched to the preview channel now correctly recognises a newer preview build and offers an in-app upgrade. And the manual download button no longer bypasses the download source you picked: it builds the download link from the currently selected mirror (GitHub official, gh-proxy, ghfast, or a custom prefix), so people who cannot reach GitHub directly can still download the package.

If you hit problems, tell us on Discord or open an issue on GitHub.

Fixed

• No upgrade button after switching a stable build to the preview channel: preview builds use versions like 0.3.6-preview.20261106-1137, which semantic versioning always ranks below 0.3.6. Switching from a formal build to the preview channel therefore reported "no update available" and only offered a download button. Timestamped preview builds on the preview channel are now recognised as a newer version, so the in-app upgrade appears after switching channels.
• Manual downloads ignored the selected download source: the download button opened the raw GitHub asset URL from the manifest, so the selected mirror only affected version-list fetching and not the package itself. The download link now applies the selected mirror prefix, so choosing ghfast.top or gh-proxy.com downloads through that mirror.

Notes

• Preview builds share one version prefix and are distinguished by build time; the "latest build" timestamp on the version page is how you tell two preview builds apart.
• This build does not yet include the fix for the Advanced settings tab strip click hot zone at 1280 width; that is still in progress.

本次更新修好了两件直接影响升级与下载的事：客户端切换更新通道后，现在能正确识别出有新的构建并给出「立即升级」；手动下载按钮也不再绕过你选的下载源，会按当前选择的镜像（GitHub 官方 / gh-proxy / ghfast / 自定义）拼出下载链接，国内直连打不开 GitHub 的人也能正常下到包。

如果你在使用中遇到问题，请通过 QQ群 或 GitHub Issues 反馈，我们会尽快处理。

修复

• 切换更新通道后没有「立即升级」：带时间戳的构建版本号形如 0.3.6-preview.20261106-1137，按语义化版本规则永远低于 0.3.6，所以从正式版切到其他更新通道时，更新检查判定"没有新版本"，只剩一个下载按钮。现在这类构建会被正确识别为新版本，切换通道后即可直接应用内升级。
• 手动下载忽略了所选下载源：桌面客户端的下载按钮直接用清单里的 GitHub 原始地址打开浏览器，选中的镜像源只用于拉取版本清单，真正下载包时没有生效。现在下载链接会按当前下载源套用镜像前缀，选 ghfast.top 或 gh-proxy.com 时下到的就是镜像地址。

说明

• 同一版本号下可能对应多个构建，靠构建时间区分；页面上的"最新编译时间"就是区分不同构建的依据。
