Magnepan and gle issues

Does anyone know the models or time frame when Magnepan corrected the glue problems on speakers exposed to sunlight? I have a pair of 1.5s that need to be placed in an area where there is sunlight. Just want to be sure.

why not speak with Magnepan to be sure, no one on the ''gone'' knows more than they do.
