If you go to the blender website (www.blender.org) you will find there the latest version available. At this moment it is 2.78c
Whatever people say, the Blender website gives you the latest version.
If there will be a next update it will be 2.79 or maybe 2.78d, but 2.8 ?????
Do never install Blender you have not downloaded from the Blender website. Be carefull !
