Proton VPN iOS 8: Kill Switch & CarPlay Upgrades

Proton VPN has released iOS version 8.0.0 on GitHub, introducing significant improvements to its iPhone and iPad application. At its core is a new Rust-based VPN engine, internally codenamed ProTUN, which replaces the older wireguard-go code. This architectural shift is designed to boost stability, improve censorship resistance, and allow for faster updates and bug fixes.

The update also makes an advanced kill switch a reality for iOS users. This enhanced feature blocks all internet access unless connected to Proton VPN and remains active after device restarts. Notably, this version improves compatibility with Apple CarPlay and allows access to local area network (LAN) devices, such as printers, even when the kill switch is engaged. While the App Store release date is unannounced, the final build's appearance on GitHub suggests it could be available soon.
