What is new in Netfluss 2.6

## VPN indicator — protected at a glance

NetFluss 2.6 shows whether a VPN is active right in the menu bar, next to your upload and download rates. It works with the **VPN connections built into NetFluss** *and* with **external VPN clients** — Tunnelblick, the WireGuard app, Mullvad, Tailscale, the macOS VPN settings and others. NetFluss detects any active tunnel, no matter which app started it.

- **Dot or shield**, in a colour of your choice — and you decide whether it stays visible (dimmed) while no VPN is connected.
- **Country flag** — optionally show the flag of the country your public IP is in, so you see your exit location without opening the popover. It updates within seconds when a VPN connects or disconnects.
- **Lightweight** — detection only runs while one of the options is on, and needs no extra permissions.

Enable it under **Preferences → Appearance**.

## Traffic Timer — measure traffic from start to stop

A new optional popover section that works like the stopwatch on your phone. Press start and NetFluss adds up everything you download and upload from that moment on — handy for checking how much a download, a backup or a video call really moves.
