Details:

in all former versions, including 5.1 and current stable (and matlab, as far
as I remember) I can use an empty cell index {} to get the element


octave:1> a={1}
a =
{
  [1,1] =  1
}

octave:2> a{}
ans =  1


but current dev returns an error instead


octave:1> a={1}
a =
{
  [1,1] = 1
}

octave:2> a{}
error: invalid empty index expression
