Description
I doubt this needs one. You couldn't jump when in shallow water before, now you can. Haven't tested it extensively so there might be some unexpected behavior. 

Installation
Use Nexus Mod Manager.

Compatibility
Modifies:
[content]\scripts\game\explorations\exploration_movement_system\exploration_substates\explorationStateJump.ws and [content]\scripts\game\player\r4Player.ws

If you have another mod that modifies those same file you can use script merger to sort it out.
