I have been receiving notices to "update" my version (2.750 (1060)). I still run Mac OS10x El Capitan. Is there anything of use in more recent updates that would make my experience any different than what I already have? I have not been experiencing any difficulties, except from time to time for a while I have to "reopen" BTT when my computer woke up.
If you are happy with the version you have, there is no need to update. You can click the „do not show again“ checkbox on the top right of the upgrade notice window.
