Autodesk Revit 2020.2.1 –
If you follow the way to get dynamo core 2.5 into revit 2020, this is probably unsupported from autodesk and I personally would suggest you never do this on a production computer. Also this will only update the core part of Dynamo and will not include any fixes/new/modified Revit nodes that could come out with the official Dynamo revit release.
There are no separate language versions for revit, all of them installed if you install one of them, you can specify which language to start in the desktop or start menu shortcut. The latest Revit version is 2020.2.1, and you should update to that if you are on 2020.2, because there is a serious bug in 2020.2. You can safely install the english version updates.
