## Version 3.13.0

_2019-02-04_

 *  **This release bumps our minimum requirements to Java 8+ or Android 5+.** Cutting off old
    devices is a serious change and we don't do it lightly! [This post][require_android_5] explains
    why we're doing this and how to upgrade.

    The OkHttp 3.12.x branch will be our long-term branch for Android 2.3+ (API level 9+) and Java

the carry bit from that addition is // brought forward to the next iteration. c2 := addMulVVW(T[i:n+i], mLimbs, Y) T[n+i], c = bits.Add(c1, c2, c) } // Finally for Step 7 we copy the final T window into x, and subtract m // if necessary (which as explained in maybeSubtractModulus can be the // case both if x >= m, or if x overflowed). // // The paper suggests in Section 4 that we can do an "Almost Montgomery // Multiplication" by subtracting only in the overflow case, but the // cost is very similar...

### Other (Cleanup or Flake)

- Added a short output format argument for `kubectl explain`. You could now use `-o` as an abbreviation for `--output` in commands such as `kubectl explain <resource> --output plaintext-openapiv2`. ([#127869](https://github.com/kubernetes/kubernetes/pull/127869), [@ak20102763](https://github.com/ak20102763))

*   `kubectl explain` now explains `apiservices` and `customresourcedefinition`. (Updated to use OpenAPI instead of Swagger 1.2.) ([#53228](https://github.com/kubernetes/kubernetes/pull/53228),[ @apelisse](https://github.com/apelisse))

- Fixed bug where explain was not properly respecting jsonpaths. ([#115694](https://github.com/kubernetes/kubernetes/pull/115694), [@mpuckett159](https://github.com/mpuckett159))

- The shorthand for --output flag in kubectl explain was accidentally deleted, but has been added back. ([#131962](https://github.com/kubernetes/kubernetes/pull/131962), [@superbrothers](https://github.com/superbrothers)) [SIG CLI]

- `kubeadm`: updated warning message when swap space is detected. When swap is
  active on Linux, `kubeadm` explains that swap is supported for cgroup v2 only and
  is beta but disabled by default. ([#120198](https://github.com/kubernetes/kubernetes/pull/120198), [@pacoxu](https://github.com/pacoxu))

- Fixed `kubectl explain` to show enum for field types if they were defined. ([#123023](https://github.com/kubernetes/kubernetes/pull/123023), [@ah8ad3](https://github.com/ah8ad3))

- Eviction requests for pods that have a non-zero DeletionTimestamp will always succeed ([#91342](https://github.com/kubernetes/kubernetes/pull/91342), [@michaelgugino](https://github.com/michaelgugino)) [SIG Apps]
- Explain CRDs whose resource name are the same as builtin objects ([#89505](https://github.com/kubernetes/kubernetes/pull/89505), [@knight42](https://github.com/knight42)) [SIG API Machinery, CLI and Testing]

#### CustomResourceDefinition OpenAPI Publishing

OpenAPI specs for native types have long been served at /openapi/v2, and they are consumed by a number of components, notably kubectl client-side validation, kubectl explain and OpenAPI based client generators.

With Kubernetes 1.15 as beta, OpenAPI schemas are also published for CRDs, as long as their schemas are structural.
