Yes, I had seen that there is a new drop-down list for font-weight and font-style in lots of places now.
However, on the Content Areas tab, the original Normal Weight tick-box option remains for all title options – there is no drop-down list (although there is one for font-style).
Similarly, on the Post Specifics tab, in the Post Title section, the original Normal Weight tick-box option remains – there is no drop-down list (although there is one for font-style).
I suspect that the title font-weight drop-downs just got missed 🙂
PS I just fixed up the titles with custom CSS pending a fix.
