## Description

It seems that some update broke the venndiagram package. The same file that worked before in the Spring 2013, now produces a wrong output.

## MWE

\documentclass{article}

\usepackage{venndiagram}

\begin{document}

\begin{venndiagram3sets}
\fillOnlyA
\end{venndiagram3sets}

\end{document}

%%% Local Variables:
%%% mode: latex
%%% TeX-master: t
%%% End:


## Evaluation

This problem is caused by a change in syntax for atan2 in pgf v3.0. Fixed in v1.1 (2016-03-16). The package now checks the value of \pgfversion to determine whether the old syntax or new syntax should be used.

It appears that the PGF version 3.0.1a has broken your fix. Perhaps you could add an option that allows the user to set \vennoldpgffalse manually. Something like,

    \usepackage[vennoldpgffalse]{venndiagram}

I'll add a package option, but it should be possible to set it manually using

\vennoldpgffalse

I've reopened this since the fix no longer works.
