FlowSphera 1.6.6 release notes

Export protocol per vendor. Settings → Devices → Connect a device offers the protocols each vendor can send (NetFlow v5, NetFlow v9, IPFIX; the recommended one marked ★), with the device configuration for each. New vendors: Palo Alto, Check Point, SonicWall, Huawei, Arista, VyOS / EdgeOS, pfSense / OPNsense, and Other with generic instructions; Linux also shows softflowd.
The description keeps the chosen protocol; editing a device preselects what it sends now. FlowTrack still recognises every packet by itself — the choice never blocks data — and the Devices page shows expected … when another protocol arrives than the description says.
Installer: the MikroTik hint uses NetFlow v9 like the web form (was IPFIX), the Cisco one names export-protocol netflow-v9, and the end of the install points to Connect a device for other vendors and protocols.
