Microsoft has released a new cumulative update for Windows Insiders running PC build 14295 on the slow ring which appears to include "improvements to enhance the functionality of Windows 10 Insider Preview". Insiders on the fast ring are already experiencing a new build, 14316, meaning this new update is for slow-ring insiders still using 14295.
Other than the standard "improvements", Microsoft does not detail what has been fixed or changed in this cumulative update. Regardless, Insiders can grab the update via Windows Update now if you're still running build 14295.
In fact, this update was pushed yesterday, but nobody appears to have noticed. Still, good to see Microsoft servicing Insiders on the slow ring.
