In 2011, the ALPHA experiment showed that the gravitational acceleration for antihydrogen was between -65 and 110 times the normal gravitational acceleration. Has there been any improvement on the value of gravitational acceleration for antimatter, whether antihydrogen or otherwise?

I know the AEḡIS (AEgIS) experiment has been working on this, but I'm not familiar with any data, not even that the value falls into the range established by ALPHA.
