I have problem with can.all.js. On IE8 error is caused in 11726 line (this.promise.catch....) but on IE 9+ console says "Promise undefined" and I can't display parts of page depends on stache templates and my page have lost js functions as usual with this type of errors. What should I do? Do I have to add 3rd part promise? On IE8 I use jquery 1.11.3.
