If we take my revision of "Put" menu arrays to add jump-on-click and
1) For the changes I made to [plot] it should be compatible in both
That is, if someone opens an old patch with a data-structure array in
Pd, makes some changes, then saves it and opens it on old Pd, the old [plot]
code should ignore the extra symbol arguments used to specify the color.
2) For changes I made to arrays, if you edit and save in revised Pd then
in old Pd it will probably break. This is because I changed graph_array
an A_GIMME, and the old graph_array specifies particular float and
For number 2, there isn't a good alternative. There's only one flag in
for the "array" message-- while I can save the jump-on-click flag there,
save an symbolic color name there, too.
Canvas args are A_GIMME, so I suppose I could append a list of symbolic
for the arrays there in a backwards compatible way.
