Error with showspeed kwarg with ProgressThresh

[KronosTheLate]

I am unable to set the showspeed kwarg when constructing a ProgressThresh:

julia> prog = ProgressThresh(1e-5, "Minimizing:");

julia> for val in exp10.(range(2, stop=-6, length=20))
           ProgressMeter.update!(prog, val)
           sleep(0.1)
       end
Minimizing: Time: 0:00:06 (18 iterations)

julia> prog = ProgressThresh(1e-5, "Minimizing:", showspeed=true);
ERROR: MethodError: no method matching ProgressThresh(::Float64, ::String; showspeed=true)

As a side-note, I am showing the progress of a process that tries to achieve some accuracy. It would be cool to be able to show something like 10/15 iterations at the end of the progress meter. That is what I am trying to do, but I do not think it is possible - the numbers will be evaluated to 0.66666 and shown as iter/maxiter.

this is a mix of old and new syntax
it will work by using kwargs for desc too:

prog = ProgressThresh(1e-5, desc="Minimizing:", showspeed=true)
