  FIRST is a post Extreme Adaptive-Optics (ExAO) spectro-interferometer
operating in the Visible (600-800 nm, R~400). Its exquisite angular resolution
(a sensitivity analysis of on-sky data shows that bright companions can be
detected down to 0.25lambda/D) combined with its sensitivity to pupil phase
discontinuities (from a few nm up to dozens of microns) makes FIRST an ideal
self-calibrated solution for enabling exoplanet detection and characterization
in the future. We present the latest on-sky results along with recent upgrades,
including the integration and on-sky test of a new spectrograph (R~3,600)
optimized for the detection of H-alpha emission from young exoplanets accreting
matter.
