There's 0 animations in 0.49 and 2 animations in 0.50
I must say that I'm very excited for 0.50, I may be exaggerating, but I believe that she will be very important.
Ami: She has shown herself to be extremely important, already knowing about the resets and the alternative timelines.
Maya, Ayane and Yumi have knowledge of the Resets (But I believe that Yumi's will be connected to Yuki's events.)
Yuki: We now have the information that she is declining because of cancer, so there is already a big plot for her.
Sara: Her events will probably also be focused on Yuki, I don't think that Selly will now enter her plot involving the gods, it will probably involve Yuki's cancer.
Noriko: She already had her first "happy event" going to another plane/dimension, which already leaves her as a possible future member of the apocalypse squad.
Niki: I believe that the events will be focused on her and Ami and maybe with Akira, the plot has already made it very clear that there will be some kind of fight between her and Sekai, so I think it will focus on that now and not so much on her and Akira.
As I said, I may be exaggerating, but I believe that this will be an update that will reveal some interesting and important information.
