You can take a look at the detailed Patch 2.5 beta 1 notes below:
NEW character: Skree
Skree, the powerful but superstitious techno shaman.
Shoot a blade that spins in position for a limited amount of time. You can shoot it forward by pressing the skill’s button and you can place it by pressing again. Pull it back by pressing a third time. The blade deals damage shooting out and coming back, and also deals damage while spinning in place.
Totem of Power
Place a robotic wall that blocks enemy movement and attacks.
Shoot Lightning that bounces to several enemies.
Skree floats on a swirling set of blades. Hold the jump button to keep floating at the same altitude.
NEW: AI modding
The AI editor is now distributed with the game. All platforms can load modded AIs, but the AI editor itself is only available on Windows. Check this topic for a guide on how AI modding works: AI modding guide
-Turrets no longer receive damage until they hit a target
-Turrets stop taking damage if they haven’t been able to hit a target for 3s while firing
-Fixed an issue where characters that can float would sometimes not be able to jump when standing on a platform that was moving down
-Improved jumping responsiveness when already pressing jump just before actually hitting the ground
-Fixed that bullet detonation did not work anymore if you had been stunned after firing the bullet
