I hope Bose here or elsewhere explaining this in a bit more detail.
1. "Improvement to the connection/disconnection" - way too vague to tell us what specifically did they improve
2. "Bug fixes and improvements" - that tells us nothing
I'm actually afraid of these "improvements" after I had to return my pair after the last "improvement" randomly turned them on by themselves. I really hope they tested this one first

So... I have QC-35's running 1.51 ... should I upgrade to the latest or keep 1.51? Wish release notes were not so dumbed down... please assume we are tech's and give us the engineering release notes.
