[NTG-context] Asymptote and Context

I am running context minimals and Asymptote on Windows.This example used to work in the past, but it seems to have stopped working. Is there anything that has changed? \usemodule[filter] \defineexternalfilter [ASY] [filtercommand={asy -tex "context" -outformat pdf -outname \externalfilteroutputfile}, output=\externalfilterbasefile.pdf, cache=yes, readcommand=\ReadImage,] \define[1]\ReadImage{\externalfigure[#1]} \starttext Testing if we can include an asymptote image \startplacefigure[location={here}, title={An Asymptote figure}] \startASY unitsize(1cm); draw((-.1,0) -- (2,0), arrow=Arrow(TeXHead)); draw((0,-.1) -- (0,2), arrow=Arrow(TeXHead)); draw((0,0) .. (1,1) .. (2,sqrt(2))); \stopASY \stopplacefigure \stoptext
