Minut receives software updates automatically to fix bugs and add new functionality. Below is a summary of improvements per public release.
Please note that most product features depend on updates to the app and cloud service as well.
Software updates are rolled out in a staggered fashion. Even though the version is listed here, it might not yet be installed on your Minut. You can find out which version is installed on your Minut in the advanced settings view in the app.
