Proton VPN Publishes iOS 8.0 Update on GitHub
The new version adds an advanced kill switch and a Rust-based WireGuard core for iPhone and iPad users.
Updated on Nov. 3, 2026 in Cybersecurity
Proton VPN has published iOS version 8.0.0 on its GitHub releases page, though the app has not yet reached the App Store. The update replaces the standard wireguard-go code with libpvpnclient, a Rust-based WireGuard implementation developed by Proton.
Why it matters
Proton says wireguard-go never integrated well with Swift, the language used to build its iOS app, so the new core is intended to address that mismatch. The change matters for users who rely on VPN kill switches to keep traffic off unprotected connections.
Proton protocols swap the wireguard-go code for libpvpnclient, a Rust-based WireGuard implementation, and the advanced kill switch blocks all internet access unless the device is connected to Proton VPN. Some DNS requests from Apple services can still bypass the VPN with the kill switch on, and the App Store release date remains unconfirmed.

The details
Version 8.0 makes the advanced kill switch available on iPhone and iPad, and the kill switch stays active after a device restart. Both kill switch modes now allow access to LAN devices such as printers and permit Apple CarPlay use.
Timeline
• Proton VPN published iOS 8.0.0 on its GitHub releases page on 2026-11-03.
• The App Store rollout date has not been announced.
The Tech Race
The update reflects a broader industry shift in which VPN providers are building their own WireGuard implementations rather than relying on the reference wireguard-go code. Proton's move to a Rust-based core positions it against rival VPN services competing on iOS performance and privacy features.
iPhone and iPad users who rely on Proton VPN can enable the advanced kill switch to block all internet access unless connected to the VPN, and it persists after a restart. Users can now reach LAN devices like printers and use Apple CarPlay with either kill switch enabled.
The takeaway
Users who depend on VPN kill switches should check their DNS settings, since some Apple service requests may still bypass the tunnel even with the kill switch active. Waiting for the App Store release may be prudent before relying on the new features.
