In reply to David.

I'm sorry, I was referring to the issue link in your previous comment.
https://github.com/Automattic/jetpack/issues/3697

I didn't experience it myself.
in my site all seem to work fine, but I only use several modules.

and I have to admit, jetpack is one plugin that's hard to debug locally.
I actually give up to test jetpack before updating (I test all updates before push them to live site for WP and other plugins).
I'm sure a lot of dev do the same because the way jetpack is built (as a Frankenstein monster).

but, awesome work in this major update and bug fix :)
