This patch fixed a lot of problems like
- UI is working in all above HD resolutions now
- some gameplay issues and stability tweaks were fixed
- movement path helper now changes colour depending on the number of Action Points
- a plugin causing the game to crash to black screen for some players is disabled now and also missing localization on one of the buttons is all right.
But there are still lot of things to fix. Let's hope for another 1.3 update soon.
