    to change, and the implementation is incomplete. This is a big new API we
    are eager for feedback.

 *  New: Support ALPN via Google Play Services' Dynamic Security Provider. This
    expands HTTP/2 support to older Android devices that have Google Play
    Services.
 *  New: Consider all routes when looking for candidate coalesced connections.
    This increases the likelihood that HTTP/2 connections will be shared.

configuration history is [tracked here](../security/tls_configuration_history.md).

Applications expected to be installed on older Android devices should consider adopting the
[Google Play Services’ ProviderInstaller][provider_installer]. This will increase security for users
and increase connectivity with web servers.

[CUDA-enabled GPU cards](https://www.tensorflow.org/install/gpu) *(Ubuntu and
Windows)*:

```
$ pip install tensorflow
```

Other devices (DirectX and MacOS-metal) are supported using
[Device plugins](https://www.tensorflow.org/install/gpu_plugins#available_devices).

A smaller CPU-only package is also available:

```
$ pip install tensorflow-cpu
```
