After a small delay, the advertised Boss Update is rolling out for Minecraft on Windows 10 and Windows phones.

The Boss Update will bring Guardians, Ocean Monuments, the summonable Wither Boss fight, slash commands, and some UI refinements to the game. Additionally, it also provides the first iteration of Add-ons, allowing people to customize Minecraft using tools as simple as Notepad and MS Paint.

You can download some example Add-ons from Minecraft.net right here, including the E3-demonstrated Alien Invasion pack and a zombie Castle Siege pack. We'll have some guides up shortly on how you can customize your own creatures in Minecraft, from the way they look, to the way they behave and interact with the game's world.

The full changelog is as follows (via Mojang):

Sadly, the update still excludes the Windows Phone version of the game from Realms, Microsoft's subscription-based dedicated Minecraft hosting service, but the company has always told me that it is their goal to bring it in, eventually, in addition to Xbox One and Xbox 360.

If you don't have Minecraft and want to see what all the fuss is about, join me, Daniel Rubino and Zac Bowden tonight on Beam.pro where we'll stream some Minecraft, chat with you about Microsoft and probably get blown up by wayward creepers!
