## Changelog since v1.3.2

### Other notable changes

* Removing images with multiple tags ([#29316](https://github.com/kubernetes/kubernetes/pull/29316), [@ronnielai](https://github.com/ronnielai))

    configuring only OkHttp's TLS sockets.
 *  Fix: Prefer TLSv1.2 where it is available. On certain older platforms it is necessary to opt-in
    to TLSv1.2.
 *  New: `Request.tag()` permits multiple tags. Use a `Class<?>` as a key to identify tags. Note
    that `tag()` now returns null if the request has no tag. Previously this would return the
    request itself.
 *  New: `Headers.Builder.addAll(Headers)`.
