Someone recently told you that the announcement on the homepage is very confusing as the 1.2.8 has a more recent date.
Ok, no more backports to 1.0.x and 1.2.x in the future, problem solved.
Well, Mr. sschwarzer was able to explain it very well:
Versions 1.2.8 and 1.0.10 are maintenance releases for 1.2 and 1.0, respectively. These may be needed if you have high backward compatibility requirements.
