Indeed. I'm trying to imagine a court saying "Well... there were damages, but they arose out of the software and not from the software, so therefore- oh, wait! The license actually includes arising "out of" the software as well as "from" the software, so I guess the limitation of liability stands. Case dismissed!"

> power and authority
Should that really be on the list? Power is the capability to do something, authority is the permission to do it. Sometimes power and authority are near synonyms, such as in frontier areas with little government, but generally in a functioning, civilized society they are quite distinct.
At least we hope and pray that is the case.
But even without getting into political debates which could get really nuanced, can't authority mean capability in this context? I'm not a native English speaker so I'm not sure, but I don't find it odd. It is also possible that these two words have different (Anglo-Saxon vs French) origin, as most of the examples listed, and that their original meaning was synonymous (of course, I'm far too lazy and tired to check that now).
"Arising from/out of X" implies that the claim was caused by X (here, the from/out of is redundant as you point out)
But "in connection with X" implies something more broader, merely that it has a nexus to X.
By joining the two, the drafter sends the signal that the intended scope is as broad as it can reasonably be. If it only said "arising from," some claims that only have a tenuous relationship to X do not fall within the scope. Parties may decide that they want the scope to be narrow, or they want to be be broad, and the language matters.
