What steps will reproduce the problem?
(1) Install an extension.
(2) Receive an upgrade to the extension that requires approving more permissions

What is the expected output? What do you see instead?
The dropdown from the menu (menu-dropdown.png) uses the phrase "It can now: [lit of permissions]". Upon first reading, this suggests to me that these are the *newly requested* permissions. That is, I interpreted it as: "in addition to what the extension could do in the past,*it can now*:"
However, it appears to be a list of all permissions.

If you visit the extension in chrome://extensions, it is already shown as upgraded but disabled. Clicking on "Permissions" shows the same full list of permissions for teh upgraded version (chrome-extensions.png).

On the one hand, it is not a bad idea to be transparent and show all the permissions.

However, the current message looks alarming than it should, and requires more cognitive overhead. Ideally, I'd like to see what the old permissions were as well as which ones changed.
Lower cognitive overhead: I want to be able to trust that I reviewed the old permissions in the past, and only think about the changes.

Is it easy to at least expose the old permissions in chrome://extensions?
