And again they do not want to cancel the update...

We thought that Shutterstock postponed this update, but again - we have same conditions as before.  

"Based on the feedback we have received from contributors, we are making changes to the requirements to accept an even larger variety of content.

In order to test these new changes we are pushing back the release of our new uploading process to next week.

The revised timeline is:

On April 15th 2019, all EPS files will need to be at least 4 MP with a new maximum MB size. We are currently working to determine the optimal limit, but it will be greater than 50MB. Our goal is to ensure contributors can continue uploading vectors of various complexity.
On April 17th 2019, a JPG will automatically be created for your vectors when you upload.
