The Forerunner 255 is eligible for another new beta update, a week or so after Garmin released Beta Version 20.21 to the ageing smartwatch. According to the company's associated forum post, roughly 50% of Forerunner 255 smartwatches have been offered Beta Version 20.23 so far. However, it should be possible to trigger the update manually by heading to the main menu on a Forerunner 255, followed by Settings, System and Software Update before tapping 'Check for Updates'.

Supposedly, Beta Version 20.23 has caused excessive battery drain on some Forerunner 255 (curr. $289 on Amazon) smartwatches. However, others report that this bug was already present in Beta Version 20.21 and has been carried across to Beta Version 20.23. Unfortunately, it seems that Garmin has not acknowledged this issue at present.

At any rate, Beta Version 20.23 is said to contain 18 changes from earlier beta updates. While Garmin has primarily focused on addressing outstanding bugs, there are a few new features and improvements to speak of, such as a refinement of how the Forerunner 255 will predict race times based on fitness levels and recent efforts. For reference, Garmin claims that Beta Version 20.23 ships with the following changes:

• Adds Garmin Share, share your workouts, courses, and waypoints between compatible Garmin devices.
• Added Device Settings Backup and Restore.
• Improvements to support pool swim workouts with pace alerts and critical swim speed.
