Apple releases watchOS 7.6.1; fixes issue that may have been actively exploited

Apple on Thursday released watchOS 7.6.1, a minor update to the watchOS 7 operating system that was released in September 2020. watchOS 7.6.1 comes two weeks after the release of watchOS 7.6, which delivered ECG functionality to new regions.

watchOS 7 features seven new watch face options — including Chronograph Pro and GMT — plus new watch face configurations users can curate, discover, and share with others.

  1. Watch updates are also possible directly by going to Settings app (on the watch), General, Software Update. It’s more convenient. And that stuff a few months ago about 8GB Series 3 needing to be unpaired and restored for each update (because not enough free space). That was nonsense from a blogger. This update installed normally. The previous two updates also installed fine for me with no special actions. It’s possible a big update, like next major release, will require unpairing and restoring. I think Apple has improved the Watch update process recently.
