One part of the Tumult Hype 4 release is an official CDN, which should be extremely useful for animators creating documents for advertising networks with very small file size requirements. In most cases, the entire size of your export is counted against your file size limit; loading the Hype runtime from a CDN will reduce your final animation filesize. The CDN is hosted by jsDelivr, with extremely fast speeds and low latency around the world. You can select this CDN for your documents by choosing the following option in File > Advanced Export:
Even if you're not coming up against a file size limit on an advertising network, a side benefit of using the CDN in your projects is that your users might already have the Hype runtime in their browser cache, thereby speeding up initial load times.
