Sometimes people post news and change them in time (like, 1 hour, 1 day). It is important to update instant view previews too.

Grab RSS feed, go through items:

  • if the item is new:
    1. send link to telegram
    2. save messages' ids
    3. save text of the item's text
  • if the item is old:
    1. compute hash
    2. check with stored hash
      • if same: do nothing
      • else: update telegram messages and resave hash

Links must have the following format:

https://mmcs.sfedu.ru/...?rhash=...&h={item text hash}
