Xcode 16.2

It looks like the tab sequence for the Time Zone screen changed in one of the releases after 15.0.

I've testing this key sequence manually and via a packer build and it works with macOS 15.1.1.

+Repository with Packer templates to build macOS [Tart](https://tart.run/) virtual machines to use with [Cirrus Runners](https://cirrus-runners.app/),
 [Cirrus CI](https://cirrus-ci.org/guide/macOS/) or [any other automation](https://tart.run/integrations/cirrus-cli/).
 
 The following image variants are currently available:
 
-* `macos-{ventura,sonoma}-base` image has only `brew` pre-installed and the latest version of `macOS` available
-* `macos-{ventura,sonoma}-xcode:N` image is based on `macos-{monterey,ventura}-base` image and has `Xcode N` with [`Flutter`](https://flutter.dev/) pre-installed
-* `macos-runner:sonoma` image is a variant of `xcode:N` with 3 latest versions of `Xcode` pre-installed and [`xcodes` tool](https://github.com/XcodesOrg/xcodes) to switch between them.

 See a full list of VMs available [here](https://github.com/orgs/cirruslabs/packages?tab=packages&q=macos-).
 
 ## 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-sonoma-xcode:N` image as well as `macos-runner:sonoma`. This generally happens within 24 hours
-of a release. Please watch this repository releases to get notified about new images.
+a new version of the `macos-sequoia-xcode:N`. This generally happens within 24 hours of 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:
 
-* `ghcr.io/cirruslabs/macos-{ventura,sonoma}-base`
-* `ghcr.io/cirruslabs/macos-ventura-xcode:{latest,14.3.1,14.2}`
-* `ghcr.io/cirruslabs/macos-sonoma-xcode:{latest,15.4,15.3,15.2}`
+* `ghcr.io/cirruslabs/macos-{sequoia,sonoma}-base`
+* `ghcr.io/cirruslabs/macos-runner:sonoma` which is a superset of `ghcr.io/cirruslabs/macos-sonoma-xcode:{latest,16.1,16,15.4,15.3,15.2,15.1,15.0.1}`
+* `ghcr.io/cirruslabs/macos-runner:sequoia` which is a superset of `ghcr.io/cirruslabs/macos-sequoia-xcode:{latest,16.2,16.1,16,15.4}`
