From my British view, without reference to a dictionary, awesome is when you hear fighter jets zoom overhead, or a metal band from in front of the stage, or Niagara Falls, or a mile-long freight train full of rocks shaking the ground as it passes. The target has strength, size and power.
An amazing thing is far beyond normal expectations in art, craft, or human behaviour. A detailed painting, where you step up closer and see it's even more detailed than you first thought. A carving from 3000 years ago with intricacy we didn't think possible at that time.
Something exciting causes strong, (mostly) positive emotions. A roller coaster ride, an impromptu water fight in the summer, stripping off clothes and running into the sea in a group, getting close to the end of a game with the realization that you might win.
Starting a job at Google and seeing 50 exabytes of data or a cluster of 10 million computers or whatever could be awesome.
Someone's clever and efficient algorithm that reduces runtime by 10× could be amazing.
Finishing the final university exam, expecting to pass the degree, could be exciting.
Changing from licence version 3 to licence version 4 is none of these. It might be satisfying, or perhaps rewarding for the people directly involved.
