and for reference, this is what it looks like in today's world, without updating the icon. It's perhaps preferable to stay with the square, but the color is painfully different and I still think two identical or near-identical icons are unnecessary.

Per Harmony spec, Yes to removing the icon. Also, here's the shorter text suggested:

Chromium couldn't update to the latest version, so you're missing out on new features and security fixes.

FWIW I think the reason the text in this particular bubble is a little lengthy is that it's explaining the rare case that an update failed and you have to reinstall completely (whereas normally Chrome updates itself and you just restart).

Since the button says "Reinstall Chromium", we might not need to repeat "You need to manually reinstall Chromium." in the body text. Do you feel differently? 

I don't feel particularly strongly, but I do think the emphasis on manual intervention is relevant.

Got it. Shall we remove the icon for this bug first?

Since we have our UX writer now, we can add this to one of string review asks in Q1. I'll file a separate bug for any new string update.

yes, I'll remove the icon. Thanks for following up on the string.

Remove last vestigial uses of "update needed" png assets.

They were out of date, and in some cases redundant. Remove
the redundant uses completely and replace the others with
references to the vector versions.

I fixed this for the pictured bubble. The recovery install global error (another similar and hopefully very rare bubble) still has an icon because there's code elsewhere that asserts that to be the case. I'll leave that one to the Harmony folks.
