Main bundle is now 10% lighter
In an ongoing effort to keep things performant, Paul has dropped support for ES5 from the main bundle of our JS SDK.
This reduces the assets you have to load by 10%, which we think is a worthy tradeoff for dropping support for older browsers, such as Internet Explorer 11 which is generally used by less than 0.5% of users.
In the rare situation that you still need to support ES5 so you can track these older browsers, we've got you covered in the docs. All you have to do is replace /static/array.js in the JS snippet with /static/array.full.es5.js to load the heavier, ES5 version.
