Thanks TryNinja for another update.
Do we need to add the new SimpleX contact or we can stay on the same if we already joined before?
I didn't notice any issues so far, but I don't know what you changed and what to expect

You don't need to do anything. If you're receiving notifications, you're good... just keep the same contact. New users can use the new address to add the bot.
I rewrote some code so the bot is more stable, so you won't notice any new features but hopefully fewer missed notifications.
