The info parameter of the function passed to DB_ENV->set_tx_recover is no longer needed. If your application calls DB_ENV->set_tx_recover, find the callback function referred to by that call and remove the info parameter.

In addition, the called function no longer needs to handle Berkeley DB log records, Berkeley DB will handle them internally as well as call the application-specified function. Any handling of Berkeley DB log records in the application's callback function may be removed.

In addition, the callback function will no longer be called with the DB_TXN_FORWARD_ROLL flag specified unless the transaction enclosing the operation successfully committed.
