Hi there, @rapidturtle ! Thanks for taking the time to reach out to the Shopify Community Forums with your question around the ‘Studio’ Theme changelog, and what you’ve noticed in the updates! My name is Imogen. It’s good to meet you!
It’s possible that our Theme Developers are working on some new theme features, as we recently announced that the Product API used in Themes and applications would be receiving changes. I am unable to provide any direct insight around what may be released in future updates, but at this time, the current product variant limit still stands at 100. It’s likely that this changelog update is referencing a change being made to the theme to accommodate these API changes. The wording included in the update appears to be misleading, so I’ve flagged this thread and that update wording for folks internally so they can take peek at the wording used to describe the update in order to prevent any future confusion around product variant limits and Studio.
For now, the information in our Help Center is the most accurate resource we can offer around the current variant limit for products on Shopify. If the product variant limit is updated or adjusted, our help documents will be updated accordingly. Thanks for taking the time to post about these changes, and bringing this to our attention!
