Garmin has put out beta update version 21.18 for both the Forerunner 255 and Forerunner 955 smartwatches. According to a post on the Garmin forum, this is a release candidate. This indicates that unless any major bugs are discovered, a public version of this software should be available to all users soon.
New Features Added
The new version brings one main feature for the Forerunner 255 and 955 devices: Garmin Strength Coach. This tool was introduced a few months ago when the previous Garmin Coach evolved into Running Coach. With Strength Coach, you can create a training plan customized to help you build muscle or improve your fitness based on your personal objectives. The change log also reveals that there are fixes for problems related to the weather glance and triathlon activity. Additionally, an issue where sleep mode would restart even after users had exited it has been fixed. You can check out the complete change log below.
How to Download
To get software version 21.18, go to Main menu > Settings > System > Software Update > Check For Updates. At the moment, about 50% of users with the Forerunner 255 and Forerunner 955 should be able to install beta version 21.18. If you have one of these devices and want to participate in the beta program, you can register through Garmin Connect.
