[Firmware ChangeLog]: What's New in 31.21 Beta | Edge 550/850/1050

Overview

Garmin has started the 20% rollout of Public Beta 31.21 for the Edge 550, Edge 850, and Edge 1050 cycling computers. This is a small beta release, but it targets two user-visible issues in training guidance and Stamina data.

Compared with the larger 31.20 beta, version 31.21 is more focused. Garmin is not adding a new feature set here. Instead, the release fixes a menu visibility issue for Daily Suggested Workouts and a data issue around Stamina Distance/Duration.

Garmin Edge 550/850/1050 Beta 31.21 Changelog

According to Garmin's official announcement, version 31.21 includes two fixes:

  • Fixed Daily Suggested Workouts showing on the main menu when toggled off
  • Fixed Stamina Distance/Duration

That makes this a narrower release than 31.20, but both fixes affect areas riders may notice during normal training use.

Why This Beta Matters

Daily Suggested Workouts should respect your setting

If a rider turns off Daily Suggested Workouts, the main menu should not keep surfacing that item. This fix is about respecting user preference and keeping the Edge main menu cleaner.

For riders who do not use Garmin's suggested workout flow, that matters. A training feature should not keep appearing after it has been disabled.

Stamina data needs to be trustworthy

The second fix targets Stamina Distance/Duration. Garmin's Stamina feature is most useful when it gives riders a reliable sense of remaining effort. If distance or duration values are wrong, the feature becomes harder to trust during long rides or structured efforts.

For Edge 1050 users especially, where the larger display makes performance screens more visible, this kind of data correction is worth taking seriously.

Branch Context: What Changed Before 31.21

Garmin's post also repeats the recent branch history:

  • 31.20 fixed crashes, Connect IQ lag/freezing, course list stability, elevation profile scaling, weather widget values, and overlay menu behavior
  • 31.18 fixed a translation issue that added "Day" to date strings
  • 31.15 added gear tracking improvements and fixed several navigation, radar, Strava widget, ClimbPro, shifter summary, and course-related issues

So 31.21 is best understood as another cleanup pass on the active 31.xx beta branch.

How to Install Beta 31.21

Garmin says you need:

  1. Enrollment in the Public Beta Program
  2. A configured Wi-Fi network on the Edge device
  3. To open Main Menu > System > About > Check For Updates

After downloading, you may need to scroll and manually select Software Update 31.21 to start installation.

If the device shows "Collecting diagnostics...", Garmin asks users to go to:

  • Menu > System > Diagnostics > Upload RAM Dump

Should You Install It?

If you are already using the 31.xx beta branch on an Edge 550, Edge 850, or Edge 1050, this update looks worth installing. It is a targeted beta, not a disruptive feature release.

If you rely heavily on Stamina screens or have disabled Daily Suggested Workouts but still see them in the main menu, 31.21 is especially relevant.

Conclusion

Garmin Edge 550/850/1050 software version 31.21 Beta is a small but practical update. It fixes a training-menu visibility issue and improves Stamina distance/duration behavior, continuing Garmin's effort to stabilize the 31.xx beta branch.

For beta testers, this is the kind of incremental update that helps make the final stable release cleaner.
