Hey there, Inanne! The current software version for the Wally receiver is U8.06 and it was released in July 2019. The previous version was U8.04. We don't have any information regarding the changes or bug fixes that were a part of each of these software releases.
If you need to download the latest version, here is a link with the steps on how to do this: https://www.mydish.com/support/products/hopper/how-to/settings/software
