Expansion tank

I will start off with saying I replaced my Thermostat and water pump a few weeks ago. I inspected my expansion tank and it looked in tip top shape well last night I discovered otherwise. I was driving home from work and looked down to discover my temp gauge was in the red....idiot light on! Pulled over and took a look. Didn't see anything so I let the car cool and only made it another 1/4 mile. Stopped got out, looked under the car and saw coolant running out . This afternoon I pulled the air intake and box to find a MASSIVE crack in the tank just below where I could see.

I will say getting the tank out wasn't difficult, just a little tricky. The hoses didn't want to pull off easy and when I pulled the tank, the bracket came with it. And yes I pulled the release clips. This is a fairly straight forward job that wasn't too challenging. I was able to do it without even getting the car off the ground.

Here is the tank:
