The biggest thing in the second patch of the EA version is the ability to customize controls from the options. Naturally all the input tips in tutorials react to the changed bindings as well.
This is what that tab in Options now looks like, it's different depending on whether you're using pad or keyboard and mouse:

Just to show something else visual, here's also a video of some weather effects improvements on the first mission (stars, clouds settings, particle fog, lighting):
Here's a full list of additions/bugfixes on this update:
- Customizable input added
- Fixed third person camera clipping through walls in certain situations
- Added VSync option
- In options, pressing cancel didn't reset the radio buttons, now they do
- Worked on the lighting and weather effects in the first mission
- Added a prompt to deleting save, and fixed some problems with prompts
- Fixed the playing time marked in saves getting reset to zero every time you get to a new mission
- Improved AI's chances of noticing player in certain situations (like after opening door), and fixed some other problems related to their sight
- Fixed a flickering between first and third person perspective when vaulting against the wall of a room (caused by the game momentarily thinking that the player is inside).
- Fixed a bug that probably came with the last update that I didn't notice: you could ram through closed doors from the inside by running at them.
- some triggers for tutorial texts came back after loading game, resulting some repeating tutorials. I fixed at least some of them, hopefully I got them all.
