Doesn't look like it to me:

 >> -data Data.Complex.Complex a = !a Data.Complex.:+ !a
 >> +data (RealFloat a) => Data.Complex.Complex a
 >> +  = !a Data.Complex.:+ !a

After a bit of searching, I guess it's this patch:

   * Fix Trac #2138: print the 'stupid theta' of a data type

So ghci didn't print the (RealFloat a) context before but does now. I'll 
fix the expected output.
