2 bugs have been fixed in the donation block:
1) It now reports an error if the balance is insufficient or if other problems occur when sending. Previously it would silently just remove the block after the comment had already been created — that wasn’t very good.
2) Stripe has been removed as an option entirely from the block. It didn’t work properly and does not allow an instant payment — that is, the same situation: a person could choose it, but the money would not reach the recipient because of SMS PIN codes, etc. Only a wallet is a guarantee.
