From mainland China / Hong Kong / Macau the page automatically picks the Aliyun OSS mirror (Shanghai region) — much faster than GitHub. Overseas users go through GitHub Releases. The switcher at the top of the matrix below lets you flip mirrors and remembers your choice.

Upgrading
SkylerX ships built-in auto-update (electron-updater). The app checks for new versions on launch and prompts you to download.
To disable, uncheck "Automatic update check" under Settings → Updates.
Windows users — upgrading from v0.5.0-rc1 / rc2 to rc3+ requires one manual step
The older updater in rc1/rc2 strictly verified publisherName. v0.5.0-rc3 temporarily removed signature verification (pending SignPath Foundation approval), so auto-update raises not signed by the application owner.
One-time manual step: download the rc3+ setup.exe or portable.exe for your platform from the matrix below and install over the top (your config is preserved). After that, auto-update works again.
Once SignPath Foundation approves the project, EV signing + strict verification will be restored and no manual step will be needed.

Code signing
Windows installers are digitally signed via SignPath Foundation — a nonprofit that provides free code signing for open-source projects.
Code signing for this project is provided by the SignPath Foundation, free of charge.
This means:
- Windows users won't see SmartScreen "unknown publisher" warnings
- The installer's authenticity can be verified through standard certificate chain checks
electron-updaterenforces publisher name matching on every update
The Foundation issues an EV (Extended Validation) code-signing certificate to qualifying open-source projects. SkylerX is grateful for their support of the open-source community.
Verifying installers
Each release ships with SHA256SUMS.txt. After downloading, verify with:
# macOS / Linux
shasum -a 256 SkylerX-0.5.0-arm64.dmg
# Then compare against the value in SHA256SUMS.txt on the Releases page
# Windows PowerShell

- Slow GitHub access in China: the page auto-switches to the Aliyun OSS mirror (top switcher); or use an accelerator like
https://github.akams.cn/as a URL prefix - OSS mirror also slow / download cuts out: click "🌐 GitHub" at the top to switch back to the original source, or visit https://skylerx-build.oss-cn-shanghai.aliyuncs.com/releases/latest/ directly and use IDM / Aria2 etc. for resumable download
- Install fails: see Troubleshooting →
- macOS says "developer cannot be verified": right-click the app → Open → confirm; or go to
System Settings → Privacy & Securityand click "Open Anyway"
