In September, Shopify sent an email announcing the planned rollout of the increase to the variant limit to 2048 for “Early October”. Since it was pushed multiple times, my hopes were not very high for it to actually release this time around (Questions about 2,000 Variants + Store Resource Limits - maxProductVariants still limited to 100?).
Checking in with other Partners, it appears, the rollout has started or maybe even already completed!
The stores of clients I checked have access to it now as well.
Finally, native bundles are more powerful and 3 products with 12 colour ways each can be combined 
Though I was surprised, that I couldn’t find any official announcements nor anything in the changelog:
The only thing that came up was a small Twitter thread: https://x.com/kirplatonov/status/1974087318383587823
I assumed Shopify would make a much bigger deal out of this.
