 %Modified the algorithm of choice of a variant of an exercise, now completely deterministic.
 % Added the command \cmd{\Acapo}. Added the serbian localization (latin alphabet).
 %The compilation produces a new file with the list of the chosen exercises.
+% Version 2.1
+% 2016/07/25
+%Modified es-german.lng and es-spanish.lng for an error in the input of the solutions. Introduced the macro randestrai.
+%Introduced the macro FPsignpol. Introduced a control on the total points of the exercises. Solved the incompatibility
+%with babel for the Spanish language. Removed the incompatibility between the command \fillin and the commands \sempli and \semplix.
