As expected, Microsoft just pushed out a new Windows 10 Insider build, the caffeinated build 14977. However, this time it’s for Mobile only, and PC users will have to wait:
We will not be releasing a PC build this week due to a blocking bug that could result in broken apps after updating to a new build.
The latest build brings EPub reading to Microsoft Edge on the phone, a feature that came to PCs with the last build, 14971.
There are also a number of other new features and some known issues, too, so make sure to check out OnMSFT.com for all the latest on Windows 10 build 14977!
