I will work on it. How about just:

This device will no longer receive software updates. You can continue using your computer but should consider upgrading. More info

yeah, I noted same text in the spreadsheet. Please do update that too.

I THINK the text at state 1 didn't show up in the product when I tested it. 

Re#3:
I can still see the text for 2 states if I set the eol status manually.
Is update_engine already aware of this change and have stopped sending security-only signals?

+deymo@ if he knows whether the eol status change has been made. 

Re #4, no, update_engine will send "security-only" state as well. Did you change your mind and removed "security-only"?

You can always just not use the security-only state from Omaha and leave the support there. What's wrong with that?

Re#6: Thanks for the clarification. I just want to understand that omaha is not changing the value of the signals. I'm fine with just remove it in the UI.
