Calbre is in a constant state of development so there is usually an update once a week: this is a real strength. You are not obliged to install each and every update. Personally I check out what's changed and only get the new version if changes relate to my use of calibre.
You can disable update notifications in Settings > Behaviour. Perhaps there could be another option "Tell me when my version of calibre is obsolete" so that at least this is shown when notifications are off.
