This update is necessary for online season players as the last version was bugged when calculating the highest pyramid floor. Thus, season 2 will be extended to Wednesday, October 13th.
In order to be ranked properly in the season leaderboard, you will have to clear the highest pyramid floor again. Players who did not update to the latest version will have their highest pyramid floor set to 0. This is necessary to determine the highest cleared floor instead of the highest unlocked floor.
I'm sorry for any inconvenience, and thank you for your understanding!
