Looks good! A few small formatting nits, otherwise good-to-go.

When you get a chance, please take a look at the release notes guide for a better understanding of how to format release notes. This specific change doesn't need one (since it's a docs and test only change), so I went ahead and removed it. Even if it had been an enhancement, though, there's a specific style we try to adhere to.
