hey @nataliefiann , have some suggestions and feedback on the layout/versioning! great job doing your first (or one of your first) versionblocks!

let me know what you think!

[mirnawong1]

thanks @nataliefiann ! have reviewed and added some comments:

• whether we should just versionblock the actual changes and not content that applies to both
• double check the improved syntax yaml because the indentation is a bit off
• do we want to add a release note as mentioned by @jtcohen6 here

hey @nataliefiann , looks good! i took the liberty to update the yaml code directly and added models at the starting point so it's consistent and adjusted the formatting.

have approved it for you, however not sure if you're waiting for @jtcohen6 to take a look!
