  Aims. The catalog of Stars With ExoplanETs (SWEET-Cat) was originally
introduced in 2013. Since then many more exoplanets have been confirmed,
increasing significantly the number of host stars listed there. A crucial step
toward a comprehensive understanding of these new worlds is the precise and
homogeneous characterization of their host stars. Better spectroscopic stellar
parameters along with new results from Gaia eDR3 provide updated and precise
parameters for the discovered planets. A new version of the catalog, whose
homogeneity in the derivation of the parameters is key to unraveling
star-planet connections, is available to the community. Methods. We made use of
high-resolution spectra for planet-host stars, either observed by our team or
collected through public archives. The spectroscopic stellar parameters were
derived for the spectra following the same homogeneous process using ARES and
MOOG (ARES+MOOG) as for the previous SWEET-Cat releases. We re-derived
parameters for the stars in the catalog using better quality spectra and/or
using the most recent versions of the codes. Moreover, the new SWEET-Cat table
can now be more easily combined with the planet properties listed both at the
Extrasolar Planets Encyclopedia and at the NASA exoplanet archive to perform
statistical analyses of exoplanets. We also made use of the recent GAIA eDR3
parallaxes and respective photometry to derive consistent and accurate surface
gravity values for the host stars. Results. We increased the number of stars
with homogeneous parameters by more than 40\% (from 645 to 928). We reviewed
and updated the metallicity distributions of stars hosting planets with
different mass regimes comparing the low-mass planets (< 30M$_{\oplus}$) with
the high-mass planets. The new data strengthen previous results showing the
possible trend in the metallicity-period-mass diagram for low-mass planets.
