+Release Date: 2 February 2022
+
+1. A new instance attribute called ``previous_generation_fitness`` added
+   in the ``pygad.GA`` class. It holds the fitness values of one
+   generation before the fitness values saved in the
+   ``last_generation_fitness``.
+
+2. Issue in the ``cal_pop_fitness()`` method in getting the correct
+   indices of the previous parents. This is solved by using the previous
+   generation's fitness saved in the new attribute
+   ``previous_generation_fitness`` to return the parents' fitness
+   values. Thanks to Tobias Tischhauser (M.Sc. - `Mitarbeiter Institut
+   EMS, Departement Technik, OST – Ostschweizer Fachhochschule,
+   Switzerland <https://www.ost.ch/de/forschung-und-dienstleistungen/technik/systemtechnik/ems/team>`__)
