FIX server now rejecting leading zeros for OrderQty

We’ve been using the exchange FIX api for years. Starting yesterday our orders started getting rejected due to invalid OrderQty. We determined this was because we were sending leading zeros, for example “004.345” instead of just “4.345”. We were able to change things and now can place orders but it was a significant disruption.

I didn’t see anything in the changelog about this change in requirements or about a new version of the FIX api. Furthermore the sandbox doesn’t have this behavior!

Can you please tell me what’s going on here?
