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

I uploaded a new version of the filter module yesterday, but the error 
below seems unrelated.

Short answer: Change `filtercommand` to `filter`.

Long answer: The standard way to specify the command to be executed in 
each snippet is to use `filtercommand`. This should be the FULL command 
(as you would run on the command line). So in case of asymptote, it should 
be:

filtercommand={asy -tex context -outformat pdf -outname 
\externalfilteroutputfile\space \externalfilterinputfile}


Since many commands are of the form:

    command-name <options> input-name

a shortcut is provided in the filter module. Instead of saying

...
filtercommand={command-name <options> input-name},
...

you can say

filter={command-name <options>}

In the example that you posted, you are using `filtercommand=....` but the 
input filename is missing, so asymptote launches an interactive promt.
