It's a small follow-up update for 1.0.16 fixing some issues with the swimming mechanic:

• Issue with entering water while holding a weapon, which resulted in weapon blocking.
  
• Issue with the character being submerger to a higher depth than required for entering swimming state, resulting in a hard animation switch.
