  Context: Exoplanets have now been proven to be very common. The number of its
detections continues to grow following the development of better instruments
and missions. One key step for the understanding of these worlds is their
characterization, which mostly depend on their host stars. Aims:We perform a
significant update of the Stars With ExoplanETs CATalog (SWEET-Cat), a unique
compilation of precise stellar parameters for planet-host stars provided for
the exoplanet community. Methods: We made use of high-resolution spectra for
planet-host stars, either observed by our team or found in several public
archives. The new spectroscopic parameters were derived for the spectra
following the same homogeneous process (ARES+MOOG). The host star parameters
were then merged together with the planet properties listed in exoplanet.eu to
perform simple data analysis. Results: We present new spectroscopic homogeneous
parameters for 106 planet-host stars. Sixty-three planet hosts are also
reviewed with new parameters. We also show that there is a good agreement
between stellar parameters derived for the same star but using spectra obtained
from different spectrographs. The planet-metallicity correlation is reviewed
showing that the metallicity distribution of stars hosting low-mass planets
(below 30 M$_{\oplus}$) is indistinguishable from that from the solar
neighborhood sample in terms of metallicity distribution.
