Since vflib is old,is any other alterative?

I am seeking a threadsafe way to
talk with gui and threads. as valuetree is not threadsafe,is there any new ways replace vflib?thanks

audio threads or some other threads? for general non-message manager thread (not audio thread) ValueTree updates I use MessageManager::callAsync

MessageManager::callAsync ([this, myData]() { myValueTree.setProperty(dataId, myData, undoManager); });

thanks ,and seems varx is good.
