The recent GW170817 measurement favors the simplest dark energy models , such as a single scalar field .
Quintessence models can be classified in two classes , freezing and thawing , depending on whether the equation of state decreases towards -1 or departs from it .
In this paper we put observational constraints on the parameters governing the equations of state of tracking freezing , scaling freezing and thawing models using updated data , from the Planck 2015 release , joint light-curve analysis and baryonic acoustic oscillations .
Because of the current tensions on the value of the Hubble parameter H _ { 0 } , unlike previous authors , we let this parameter vary , which modifies significantly the results .
Finally , we also derive constraints on neutrino masses in each of these scenarios .
