It seems there is no Riseup VPN 3.. available for download. Riseup, the company behind this VPN service, has been releasing new versions of their software regularly. If you're looking for the latest version, I recommend checking Riseup's official website or their support page for the most up-to-date information on available updates and versions. If you are looking for a VPN that is actively developed by Riseup, you can download the latest version directly from their official website: Riseup VPN. From there, you can navigate to the download section and download the latest version of their VPN service.
