We release new features at a scheduled period of time with updated UI. The team has to update content ahead of time but not publish it until the feature has been released/updated.

Content Block is great to update many articles at the same time, however, one issue with using Content Block is that it can't be scheduled, making changes to the Content Block will update any published article that's currently using Content Block - whereas we have a specific date it needs to be updated. Here's a reminder notification that shows up when you update a Content Block.

By the way, Content Block is great, especially since you can now update the images as well! Scheduling Content Block, just like how we schedule articles will be really helpful in planning and preparing.
