Today, Microsoft posted to the Feedback Hub that it's releasing Windows 10 for PCs build 15063.11 to the Fast and Slow rings. It would mark the first cumulative update for the RTM build of the Creators Update, but there's just one problem: the firm never actually released an update.
Indeed, if you check for updates on a Fast or Slow ring PC, you won't find any, and the Feedback Hub post has since been removed. Here's what it originally said:
We need Windows Insiders to help validate the first Cumulative Update to go out for the Windows 10 Creators Update which is set to begin rolling out to customers around the world on April 11th, Today we are releasing a Cumulative Update Build 15063.11 (KB4016250) for PC to Windows Insiders in the Fast and Slow rings. This Cumulative Update brings the following fixes:
We fixed an issue where on Surface devices, Bluetooth radio fails to re-enumerate during hibernate/resume.
We fixed an issue with McAfee Enterprise to prevent a system crash when the product driver is installed on build 15060 configured with Device Guard.
As always, please keep sending in feedback via Feedback Hub.

We've reached out to Microsoft for more information about this update, but for now, we can only assume that it was posted by mistake and it will likely be available later on today.
The Windows 10 Creators Update will launch for PCs on April 11, with phones coming later on April 25. PC users, however, will be able to manually install it via the Update Assistant beginning on April 5.
Update: Microsoft's Brandon LeBlanc confirmed via Twitter that the update is coming later today.
