There is a dedicated command in the help menu for bug reporting that will fill all of this information automatically for you. Go to Help -> report bug.
Apparently they solved the problem of not being able to select the Hash information by removing it directly. Really?
Apparently now when I try to give support to users in forums and I want to know exactly the Blender build that the user is using, I’m going to have to waste more time to access the date/hash of my version, and to explain to the user how he should do to see the date/hash in his build.
Still trying to figure out how to access to hash information in builds. Edit: Help > Save system info
