my new lid came today, i have attached a picture. the difference is the full lip inside the lid. Looks stronger and the oring fits and stays in place better than the previous one.
Found this videos that explain what changed on the lid(took them from TVS website) , they are still red, but mine has a lip on the inside to better hold the bung (briefly shown on the videos).
but what i noticed the most is the oring seals and installs easier (on the ones i just got).
I also found out that there is a V2 of the lid and oring combo. They work much better than the previous ones and they work on the old Fermonsters as well, i just bought new lid and oring and did not have to replace the fermonster. :) available at MB.
