Is Ignition 7.5.1 compatable with AB firmware 21.11

Do you guys keep an up to date product compatibility matrix?

I’m currently working on rolling back a PLC project from V21 to V19 due to Ignition incompatibility, and I did not see any caveats on this page: inductiveautomation.com/products … drivers/ab

Are there any workarounds at the moment?
