Microsoft continues its testing of Windows 10 Mobile, with a new build hitting the company's internal Fast distribution ring. As noted by Windows Insider chief Gabriel Aul, build 10547 is currently in testing.
In response to a question on Twitter, Aul had this to say:
10547 is now in our internal Fast ring.
Aul did not say that 10547 would be the next build heading out to Windows Insiders, though it's certainly a possibility. He did note that no new build of Windows 10 Mobile would be released today. Windows 10 Mobile Build 10536 launched to the Windows Insider Fast ring earlier this week.
