*  Fix: Target Java 8 bytecode for Java and Kotlin.


## Version 4.0.0-RC3

_2019-06-24_

 *  Fix: Retain binary-compatibility in `okhttp3.internal.HttpMethod`. Naughty third party SDKs
    import this and we want to ease upgrades for their users.


## Version 4.0.0-RC2

_2019-06-21_

 *  New: Require Kotlin 1.3.40.

* Third Party Resource tests in the e2e suite were incorrectly marked as part of the conformance bucket.  They are alpha and are not required for conformance. ([#52823](https://github.com/kubernetes/kubernetes/pull/52823), [@smarterclayton](https://github...

- `Kubelet` no longer creates certain legacy iptables rules by default.
  It is possible that this will cause problems with some third-party components
  that improperly depended on those rules. If this affects you, you can run
  `kubelet` with `--feature-gates=IPTablesOwnershipCleanup=false`, but a bug should also be filed against the third-party component. ([#114472](https://github.com/kubernetes/kubernetes/pull/114472), [@danwinship](https://github.com/danwinship))

* `apply` falls back to generic 3-way JSON merge patch for Third Party Resource or unregistered types ([#40666](https://github.com/kubernetes/kubernetes/pull/40666), [@ymqytw](https://github.com/ymqytw))

#### Updates to edit

[SIG API Machinery][] is responsible for all aspects of the API server: API registration and discovery, generic API CRUD semantics, admission control, encoding/decoding, conversion, defaulting, persistence layer (etcd), OpenAPI, third-party resources, garbage collection, and client libraries.

- Fixed a bug in the single-numa-node policy of the TopologyManager.  Previously, pods that only requested CPU resources and did not request any third-party devices would fail to launch with a TopologyAffinity error. Now they will launch successfully. ([#83697](https://github.com/kubernetes/kubernetes/pull/83697), [@klueska](https://github.com/klueska))

- The underlying format of the `CPUManager` state file has changed. Upgrades should be seamless, but any third-party tools that rely on reading the previous format need to be updated.

* [Kubelet] Check if kubelet is running as uid 0 ([#30466](https://github.com/kubernetes/kubernetes/pull/30466), [@vishh](https://github.com/vishh))
* Fix third party APIResource reporting ([#29724](https://github.com/kubernetes/kubernetes/pull/29724), [@brendandburns](https://github.com/brendandburns))
