updateChat

Chat (chat and/or chatFull) information was updated.

This update can only be received through getDifference or in updates/updatesCombined constructors, so it will always come bundled with the updated chat, that should be applied as usual », without re-fetching the info manually.

However, full peer information will not come bundled in updates, so the full peer cache (chatFull) must be invalidated for chat_id when receiving this update.

Peer database

Many constructors in the API need to be stored in a local database upon reception and should only ever be updated reactively (passively) when received via updates or by other means (as specified in the documentation), to avoid overloading the server by continuously requesting changes for the same unchanged information.
