Wow, I’m so happy about those panic message improvements. With the formatting before, most users’ brain probably already melted while reading thread 'main' panicked and the custom message looked like it was just more tech lingo in the middle there.

In reality, that custom message is often the only info relevant for users, and really the most useful info for me, too.

Love the stabilization of div_ceil and some of the other unsigned integer functions. They definitely make writing some algorithmic code easier.

So, I will finally be able to drop some deps and use the built-in chown. Nice!
