It's a new week, which means that Microsoft released new Windows 10 Insider Preview builds to the Fast ring: 16257 for PCs and 15237 for Mobile. But it's also a new month, which means that Slow ring users are seeing some love as well.
Build 16251 replaces 16232 in the ring, which was offered on July 7, and it brings quite a few new features, which Fast ring users have seen over the course of three releases. These include Fluent Design improvements, the ability to link your iPhone or Android phone to your PC, and more.

A Slow ring PC build also means that there will be new ISO images and an SDK Preview on the way. Most likely, we'll see those within the next week. Of course, if you want to do a clean install, you can always use the 16232 ISO, upgrade to 16251, and perform a reset.
If you're on the Slow ring, you can get today's build by going to Settings -> Update & security -> Windows Update -> Check for updates. If not, go to the Windows Insider Preview tab and click 'Get started'.
