Package braids warning

Anyone run into this warning?

Package braids Warning: This package was designed using PGF2.10; you are using 3.0.1a.

I made sure that I had usepackage{tikz} before usepackage{braids}. The actual code for the braid is

begin{tikzpicture}
braid[number of strands=4,
       style strands={5,6}{draw=none}] (braid) a_2 a_1 a_3 a_2 a_2 a_1 a_3 a_2;
end{tikzpicture}
