I have seen testnet API response all pairs with
"permissionSets": [],
Which was used to check if a pair is eligible for trading. Now all pairs on testnet is not trade-able. I have look at most recent change log binance-spot-api-docs/testnet/CHANGELOG.md at master · binance/binance-spot-api-docs · GitHub but didn’t see anything related.
I just want to know if this can propagate to production API and prepare for it.
