@a-mccarthy : Is this the correct date for publication? If not, please could you confirm what this needs to be?

Per the filename, I'm guessing it should be 2024-08-21

Per #47054 (comment)

The current statement is likely to confuse users, as they might think they need to be on the latest version of the CRI for this to work. From the information given below, it would make more sense to say supported instead of new enough.
