Avalon Ship Swap?

We are still 6 weeks away from sailing Budapest to Amsterdam on the Vista. With all of the recent low water issues on the Danube has Avalon done any swaps recently?

I know from posts here they cancelled one cruise and modified 2 others. There hasn't been an new updates from Avalon in the past week.

I've been reading on the threads about Scenic and Viking doing swaps but haven't heard any news from the Avalon fleet.

Has anyone recently sailed with Avalon, how have the been handling the low water issue?
