In the past both Mono and Xamarin.iOS are updated frequently to catch up with the requirements. That's why it was important to show which Xamarin.iOS release maps to which Mono release.
However, now all Xamarin.iOS projects should migrate to .NET 6/7 iOS/MAUI, so Mono hasn't been updated for long https://www.mono-project.com/docs/about-mono/releases/ Likely 6.12.0.182 will be the last release of Mono, so no need to update release notes.
