 ## Release Cadence
 
 Once a new version of Xcode is released, we will initiate a GitHub release which will automatically build and push
-a new version of the `macos-sequoia-xcode:N`. This generally happens within 24 hours of a release.
+a new version of the `macos-{tahoe,sequoia}-xcode:N`. This generally happens the next weekend after a release.
 Please watch this repository releases to get notified about new images.
 
-For an Xcode release which is non beta and not an RC `ghcr.io/cirruslabs/macos-runner:sequoia` image will also be updated.
-
 ## Update Cadence
 
-Some of the images are regularly getting rebuild in order to update the pre-installed packages. The following images are updated
-monthly on the first Saturday of the month:
