As we build new features, we immediately release them to partners that are a part of our Beta Program. Once these features have been refined, they will be released to our non-beta partners.
You can join our Beta Program right from Partner Center. Head to the Customize tab, then select General Product Settings. Next, turn on Enroll in Beta Program. If you are using Markets, you can also select only a specific Market to be on Beta.
If you aren't enrolled in the Beta Program, you will get access to those features at a later date. ETA's will be specified in the Product Release Calendar.
