No way to handle message unpin

[Vilin97]

Hi.
It looks like message unpinning is not exposed in the API at all, is this correct? My bot remembers pinned messages, but I want it to forget the pinned message when it gets unpinned. I found no way of doing it, since message unpinning does not send any status update (unlike message pinning).

Is this on the TODO list?

Same here, when the bot pins a message, but the user unpins it - the bot does not get informed about this fact!
