Big Sur gets a version-bump to 11.6.1, while Catalina gets an old-version-style patched labelled Security Update 2021-007, but not a version number change.
Importantly, these updates retrofit the iOS 15.0.2 patch to the Watch and TV product lines.
As well as announcing and documenting the abovementioned 8.1 and 15.1 versions for watchOS and tvOS, two bulletins provide "Catchup" documentation for the previous updates numbered watchOS 8 and tvOS 15.
The good news is the arrival, at last, of the zero-day patches for watchOS and tvOS, and the fact that none of the other updates mention the dreaded words "This issue may have been actively exploited".
Use Settings > General and choose Software Update on your iPhone or iPad. Use Apple menu > System Preferences > Software Update on your MacBook or desktop Mac.
Big Sur should now be 11.6.1 Catalina should still be 10.15.7 but with Security Update 2021-007 iOS 15 should now be 15.1 iPadOS 15 should now be 15.1 iOS 14 should now be 14.8.1 iPadOS 14 should now be 14.8.1 iOS 12 should still be 12.5.5 tvOS should now be 15.1 watchOS should now be 8.1 Recommended reads.
