This is the release that bundles what will probably be the final iteration of the updater.
While bug-fixes to it may be required here and there, the updater should be able to pull enough in to repair itself automagically.
This release also heralds the dropping of the /latest-release branch, as it is no longer required - updates will be handled through tag-based releases from now on.
I still suggest updating through Git if you can at all, but the --update flag should be perfectly reasonable now as well.
