Summary

This release has bug fixes and other items listed below, but it has two significant pieces of work that have been a huge effort from our small but passionate team. 

First is a connectivity/stability piece of work. This should create improvements to how stable your connection is, with less ‘going dark’. It should also improve the onboarding process reliability, improving the connection in those moments to create a smoother experience.  
 
The second we're extra excited about. We’ve been working away on a significant piece of color work to unify the entire range into one 'truer' color space. This has been an enormous body of work to bring generations of tech and products together with scientific testing and visual calibration to create a unified visual profile.  

There are some security improvements too, but we don’t think those will change your experience day to day—but they’re always nice to have. 

We will be sending out surveys about these two experiences in particular in a week for your thoughts.  

Happy testing!
