When announcing new features, provide COMPLETE information about who the feature applies to.
When you (MS) announce a new PowerPoint feature, please provide enough information for users to know whether or not they should expect to RECEIVE that feature. Otherwise you're wasting untold hours of our time. Tell us the Office version(s) the feature appears in, the "ring" (normal, Insider Slow, Insider Fast), whether it's subscription only or MSI versions (and include a link to a page that explains to users how to tell which they have), and if it's relevant, which version and release of Windows users need in order to take advantage of the new feature. Personally, from now on I intend to ignore any feature announcements that omit this basic information.
This is related, but may be a separate request. Need ability to allow users to force update ahead of roll out schedule. So if feature is rolling out to Monthly Targeted (Insider Slow), ability for a user on Monthly Targeted to manually force the update to install is needed, especially for users that answer questions, provide training, test for corporate use, etc.
