New release of multi-backend Keras: 2.3.0 

- First release of multi-backend Keras with full TF 2 support
- Continued support for Theano/CNTK
- Will be the last major release of multi-backend Keras

We recommend you switch your Keras code to tf.keras.

Both Theano and CNTK are out of development. Meanwhile, as Keras backends they represent less than 4% of Keras usage. The other 96% of users (of which more than half are already on tf.keras) are better served with tf.keras.

Keras development will focus on tf.keras going forward.

Importantly, we will seek to start developing tf.keras in its own standalone GitHub repository at keras-team/keras in order to make it much easier for 3rd party folks to contribute.

Keras has never been moving faster than now :)
