Today Microsoft pushed another cumulative build 14342.1004 for Redstone branch. There are no new futures in this build. It only fixes the battery issues for some devices.
We are releasing Build 14342.1004 today for Windows Insiders in the Fast ring. This build is exactly the same but with some additional fixes including a fix for the battery life issues we were seeing on some devices such as the Lumia 930, 929 and others which was also causing these devices to get hot.
As you can see there is nothing new with this update. In case you want to see full changelogs of build 14342, you can take a look at What’s new in Windows 10 Mobile build 14342.
