Can someone please help me to understand updates? When I click on "What's new?" in the opening OR window, I am shown a list of updates. The U2020 numbers of each are different but the content of the most recent two or three are often identical (including all the Pull Request #s).

I can't tell you the details of all David, but I can give you a general idea.
From working with Peter on vacuum brakes - a small change will be made - say release on one type of brake valve.
Than another day a small change might be made reflecting the behaviour of a different brake valve.
The a bug might be noticed - perhaps one of the changes does not work well with another example that has already been completed.
So what you see is a summary of the big area, but each new update might have just a tiny change.
Regards
Darwin

Thanks for the clarification Darwin.
