as yet
Up till now
As yet means up to this point in time, with an implication that things may change: The results are as yet unknown.
It's slightly more formal than "yet" alone and often appears in negative constructions: As yet, no one has claimed responsibility.
The phrase emphasizes that a situation remains incomplete or unresolved.
