Splatoon 2 has updated, bringing a host of changes and some new toys to play with.
The most immediate change is a new Salmon Run stage called Lost Outpost, which is immediately available. Manta Maria is a new main stage for Turf War and ranked modes and will be available on standard update time Friday night (North American time). A new weapon, the Forge Splattershot Pro will arrive in time for the next Splatfest, and include the new Bubble Blower special in its arsenal.
The 1.2 update made additional changes to weapon balance and added fixes for glitches. Full information can be found here.
