Contributions summary:Kestutis primarily worked on the `ProtonVPN/win-app` repository, focusing on low-level network interface manipulation within the Windows environment. Their contributions involved modifying the application to exclude specific network interfaces, particularly OpenVPN TAP, from IPv6 protection. They implemented functionality to enable or disable IPv6 on network adapters and added the ability to set and delete default gateways. This indicates a focus on core network configuration and control within the VPN client.
