Today, Microsoft issued the fourth Windows 10 Insider Preview build in a row with no new features. Yes, the end (of RS5 development) is nigh.

“Today, we are releasing Windows 10 Insider Preview Build 17744 (RS5) to Windows Insiders in the Fast ring,” Microsoft’s Dona Sarkar announced.

The blog post then goes on to list several small changes, improvements, and fixes in the build. And a handful of known issues.

My expectation is that Microsoft will complete the development of this Windows version—Windows 10 version 1809—by the end of the month. And will ship it, earlier than originally expected, by the end of September.
