Warning

Client sync fields do not automatically detect changes. When changing a client sync field, call ISyncManaged.syncDataHolder.markClientSyncFieldDirty(FIELD_NAME)

@DescSynced -> @SyncToClient
@RequireRerender -> @RerenderOnChanged
@Persisted -> @SaveField
@UpdateListener -> @ClientFieldChangeListener on listener method.
@DropSaved - Removed, make machines implement IDropSaveMachine instead
@ReadOnlyManaged and @LazyManaged See usage docs for instructions on complex sync objects
