An API push-receiver relies on will be deprecated in June

[ghost]

According to this issue, push-receiver calls https://fcm.googleapis.com/fcm/connect/subscribe, which will be removed on June 20th this year. There's a replacement library, Arcana, which supposedly does everything push-receiver can do.

This fork uses the updated endpoints: https://github.com/javajuice1337/push-receiver-v2
So I guess that it could be used as a more drop-in replacement.

Fixed in v2.5.0
