KB3140742 brings Windows 10 Build 10586.112, it seems. (Thanks to
@sergey_karavan for the screenshot).
A new cumulative update has been seen in the Microsoft’s Update Catalogues. The KB3140742 update is available for both X86 and X64 systems and seems to be the next Build version update for the Windows 10 version 1511, or the RTM Build 10586.
It may bring Build 10586.107 or higher to Windows 10 devices running Build 10586.104, as it replaces the KB3135173, the cumulative update that brought Build 10586.104. Check in the screenshot below,
Microsoft has released Windows 10 Mobile Build 10586.107 to both Fast and Slow Ring Insiders, so it may be coming to Windows 10 too.
