Yeah. Well. No.
Facebook is not good for this kind of information. I have all sorts of notifications enabled and yet I did not see this message.
But even if I did, this is not the way to handle important updates. There should be one single stream of official communication where (1) all sorts of important changes are announced in advance and (2) people are push-notified to update.
Specifically, I remember when the Number formatter update was announced. But do I have to remember if I have used every component that is getting deprecated one day? Do I need to remember where I have used it?
This kind of announcement sucks, it is worded as if it is the users' fault. Quite a bit ironic for a company that offers automation, not to be able to automate the process of informing its users that a change is coming, or has been enacted, and that they should plan ahead and switch at an opportune time.
Not to mention that the change itself required me literally to copy/paste some text strings from one block of fields to another. The format of the service did not change, why isn't there a single-click update function to port these values into their new placeholders? Why is even updating required and why aren't deprecations migrated silently?
This is the first time I am getting really pissed with the service, and that is because this is something very simple to improve. I did not have to rush back to my PC after work hours to update a time critical parser. It was something that could have been handled way better.
