The Beam Test Facility (BTF) at the National Laboratories of Frascati provides highly configurable positron/electron beams for different type of experiments. Extracted from the DAΦNE LINAC, the beam delivers up to 49 bunches/s, with 1 to 10^10 particles/bunch. Secondary beams span 25-780 MeV (electrons) and up to 550 MeV (positrons). BTF includes two experimental halls: BTFEH1, suited for high-intensity and long-term experiments, and BTFEH2, optimized for lower intensities (up to 10⁶ particles/s). Both halls feature remote-controlled movable tables, beam diagnostics, and essential services like laser alignment, networking, high-voltage support, and gas pipelines, ensuring comprehensive experimental capabilities and 24/7 user support. A notable strength of BTF lies in the user-friendly approach: beam is easily manipulated to meet users' specific needs, even during ongoing data collection. In this talk the upgrades concerning the development of a new control system based on Epik8s (EPICS on Kubernates) will be reported as well as the new improvement in beam dimension and energy loss concerning the substitution of the 500 m BeO exit window with 120 m Anticorodal one.
