Learn English – the difference between “has since” and “since then” and which is better here

In these sentences the two verbs are completely interchangeable. There is no significant difference.

Elsewhere there would be differences, of course. Animate objects tend to grow and inanimate objects tend to expand, for instance. Even in those usages there are often cases where the two verbs could be swapped.

"To inaugurate" is fairly archaic in American English. We say people get inaugurated in political office, or to inaugurate a new policy. I couldn't tell you exactly what the difference is, but I can't remember the last time I heard someone use the word for anything but a new president.

To say something "launched" implies movement, and a certain element of risk. Its usage is metaphoric, as literally speaking only vessels launch. When you "launch" a new software, you are taking it from its safe harbor (the development team) and putting it out into the dangerous seas (the general public). It used to imply adventure and risk, but is now sufficiently commonplace that people don't normally think of it that way. "Released" is a more neutral word for the same thing.
