So, it's been a while since Mojang released the snapshots that precede a full new patch release for the game, but the time has finally come again.
1.9 is called the Combat Update and already we know that a lot of things that will be added to or overhauled this time round have to do with the combat and PvP elements of the game. This snapshot though introduces some very early versions of the things that mostly don't though.
The two main features of this snapshot are the dual-wielding/dominant left hand feature that many have wanted to see added to the game for some time and the new levitation effect that you get from potions and the new Shulker mob.
Dual-wielding is not yet finished, but already we can tell you that it's not possible to wield two swords at once. Sorry. It is possible to use a bow though while holding something like a torch in your offhand though, although this could be patched out before 1.9 releases properly. Dual-wielding will mean that mining will also be a bit easier, as you can now use a pick and hold torches to place at the same time. There's also a few bugs and quirks to be worked out with the dominant left hand feature too, although the b and c versions have at least nixed a few already such as certain actions reverting you back to default righty.
The levitation effect too is still a bit unfinished, but at least we can tell that certain levels of effect applied will make a difference. More levitation effect means a faster rise into the air, while a little effect can actually make it seem like you're on a low-gravity planet when you descend back down to blocky earth. Of course, if you've played on any Minecraft server in the last few years, you'll know that the game can and often will kick you for 'cheating' if it thinks you're using a cheat to fly in Survival. That used to happen with the levitation too until it was patched out in the b version of the snapshot.
As always, if you want to play with this snapshot remember to backup your worlds just in case. Especially with this one, Mojang admit themselves in their blog that this is a very early Alpha stage snapshot and had a lot of potential to mess things up.
