about the parameters in post data of version 1.10

hi, Allan and all

i found Datatables have released a new version 1.10, and i found that the parameters in post data have changed.

in old versions: parameters of post data may be: sEcho, sColumns, iTotalRecorders, iColumns, and so on.. in new version of 1.10.x, i found only find the paras below: draw, start, length, order[i][column]...

is there a clear way to find the column numbers from the paras?
