If you were expecting an early week new build, then you might want to hold your breath for a couple more days. It has only been about three days since build 15019 dropped, and Dona Sarkar and the Windows Insider team need a few more days to look at data, so a new build will not come on Monday, or Tuesday for both PC and Mobile.
No Mobile builds M/T either, we are looking for a good build candidate for the bug bash which starts on Friday. #WindowsInsiders

The announcement from Dona Sarkar means that a new PC Windows Insider build could come on Wednesday, Thursday, or Friday. For Windows 10 Mobile, meanwhile, Dona and the Windows Insider team are still looking for a good build candidate for Friday's bug bash, so there also won't be new mobile builds on Monday or Tuesday.
These kinds of early morning tweets from Dona have become routine, so we urge you to stay tuned to us here at OnMSFT, as we will be here to cover the new build once it's live. Until then, let us know when you think the new build will drop by dropping us a comment below!
