In previous versions (V4.5.x), some users reported momentary bandwidth spikes that caused a 1-2 second freeze during high-motion scenes. introduces a new "Dynamic Buffer Allocation" algorithm. In real-world tests, this reduces packet loss by approximately 15% when switching between cell towers. If you stream from moving vehicles (like a marathon chase car), this update is essential.
