When were the current Germany home and away football/soccer shirts released?

Question

Thinking of buying one of these shirts but I don't know when they were put up for sale. I don't want to buy it and then find out that there is a new one coming out a month later. Also if you know when the new ones are released could you please say.

Answer 1

I thought that they were released before the start of The European Championships. I saw them for sale in Hamburg in May.
