Increase Datatip display precision (2014b)

It appears that Mathworks has changed the internal architecture of MATLAB sufficiently such that the old method of increasing the Datatip displayed precision (via editing default_getDatatipText.m) is no longer possible. The file and directories no longer exist.

Has anyone been able to accomplish the same result in the new software (2014b, for example)?

Thank you,

I'd also like to know.

Can you use the UpdateFcn of the datacursormode

function txt = myupdatefcn(obj, event_obj)
pos = event_obj.Position;
txt = {sprintf('X: %.16g', pos(1)), sprintf('Y: %.16g', pos(2))};
