  Important revisions of the solar model ingredients appear after 35 years of
intense work which have led to an excellent agreement between solar models and
solar neutrino detections. We first show that the updated CNO composition
suppresses the anomalous position of the Sun in the known galactic enrichment.
The following law: He/H= 0.075 + 44.6 O/H in fraction number is now compatible
with all the indicators. We then examine the existing discrepancies between the
standard model and solar - seismic and neutrino - observations and suggest some
directions of investigation to solve them. We update our predicted neutrino
fluxes using the recent composition, new nuclear reaction rates and seismic
models as the most representative of the central plasma properties.
  We get 5.31 +- 0.6 10^6/cm^{2}/s for the total ^8B neutrinos, 66.5 SNU and
2.76 SNU for the gallium and chlorine detectors, all in remarquable agreement
with the detected values including neutrino oscillations for the last two. We
conclude that the acoustic modes and detected neutrinos see the same Sun, but
that clear discrepancies in solar modelling encourage further observational and
theoretical efforts.
