mullvad/mullvadvpn-app 2026.3-beta1

on GitHub

This release is for desktop only.

Here is a list of all changes since last release 2026.2:

Added

• Add port setting for LWO obfuscation.
• Add list of recent server selections in the select location view.
• GotaTun is now used as the userspace WireGuard implementation on all desktop platforms, not just
  macOS. It replaces wireguard-go.

Changed

• Optimize LWO performance. This gives a 1.5 to 3 times speedup in our benchmarks.
• Change default retry connection attempts. LWO is now the third default
  constraint. The relative order among the following constraints is preserved.

Linux

• Switch memory allocator to jemalloc to reduce fragmentation.
• mullvad-early-boot-blocking.service now waits for local file system to be mounted
  (After=local-fs.target). This was assumed before, but not required (and is still not required).
• mullvad-daemon now installs the same shutdown handler for SIGHUP as SIGINT and SIGTERM.
• mullvad-daemon now exits without tearing down firewall rules on SIGUSR1.
  This is used to avoid leaking network traffic when restarting systemd service.

macOS

• Restart the GUI after an update if it was running.
• mullvad-daemon now installs the same shutdown handler for SIGHUP as SIGINT and SIGTERM.

Fixed

• Fix duplicate "Connected"/"Disconnected" desktop notifications caused by the daemon sending
  multiple consecutive tunnel state events for the same state.
• Fix GUI appearing stuck in "Disconnecting" state when daemon transitions directly from error to
  disconnected.
• Fix QUIC obfuscation not always being used if relays only had IPv6 addresses for QUIC.
• Fix a bug with Shadowsocks-based API access methods where some ciphers were configurable by
  Mullvad VPN clients while not being supported by the system service.
• Fix IPv6 addresses not being allowed as endpoints for Socks5 and Shadowsocks API access methods.

Linux

• Fix 'mullvad split-tunnel clear' getting stuck.

Windows

• Fix potential access violation during cleanup on ARM64.
• Fix conflicts caused by some other VPN clients that depend on Mullvad's split tunnel driver. Note
  that split tunneling still cannot be used simultaneously in different clients.

Security

• Remove ability for renderer process to execute arbitrary binaries. This is a defence-in-depth
  measure to ensure that the renderer process does not have any capabilities beyond that of a
  regular user of the app. Affects platforms with the in-app updates feature, i.e. macOS and
  Windows. Fixes GHSA-h72f-j6r4-c3jc
