possible for large applications to migrate incrementally. The Maven group ID
is now `com.squareup.okhttp3`. For an explanation of this strategy, see Jake
Wharton's post, [Java Interoperability Policy for Major Version
Updates][major_versions].

This release obsoletes OkHttp 2.x, and all code that uses OkHttp's
`com.squareup.okhttp` package should upgrade to the `okhttp3` package. Libraries

* Kubernetes version command line parameter in kubeadm has been updated to drop an unnecessary redirection from ci/latest.txt to ci-cross/latest.txt. Users should know exactly where the builds are stored on Google Cloud storage buckets from now on. For example for 1.9 and 1.10, users can specify ci/latest-1.9 and ci/latest-1.10 as the CI build jobs what build images correctly updates those. The CI jobs for master update the ci-cross/latest location, so if you are looking for latest master builds,...
