Important Wear OS update rolling out now to Fossil smartwatches

According to a new thread on Reddit (via XDA), a new Wear OS update is now rolling out to several Fossil smartwatch models. This is supposedly Wear OS H-MR2, an update detailed by Google back in August.
A short changelog posted on Reddit reveals some of the improvements added with the Wear OS H-MR2 update. Some of the changes have been teased by Google six months ago, like the new weather app and improved performance, while others are completely new:
- Ability to turn off Long Press Power Button to activate Google Assistant
- Ability to set the screen off time limit
- New screen brightness layout
- Tile limit increased. You can now have more than 5 tiles. I managed to add 10.
If nothing bad happens during the rollout, those who own a smartwatch manufactured by a brand under the Fossil Group should receive the update in the following days.
