You can see the list of changes in:

I haven't seen any change related to the web inspector, it must be side
effect of another change. The internal changes are related to
accessibility and the ANGLE sources that were updated. There aren't many
changes, so I think you could try to bisect to find the revision that
introduced the regressions.

Yes, we have fixed several crashes in the printing code.

In this case I would also suggest to revert the printing commits one by
one until the problem is fixed to identify the bad commit.

You can see the changes in the trac as well.
I recommend you to clone the git repository, so that you can easily see
the changes and run bisect to find the bad commits
