# Release 2.6.0

## Breaking Changes

*   `tf.train.experimental.enable_mixed_precision_graph_rewrite` is removed, as
    the API only works in graph mode and is not customizable. The function is
    still accessible under
    `tf.compat.v1.mixed_precision.enable_mixed_precision_graph_rewrite`, but it
    is recommended to use the
    [Keras mixed precision API](https://www.tensorflow.org/guide/mixed_precision)

    
    From: [@mikedanese](https://github.com/mikedanese):
    Instead of aliasing. Aliases are annoying in a number of ways. This is
    specifically bugging me now because they make the action graph harder to
    analyze programmatically. By using aliases here, we would need to handle
    potentially aliased go_binary targets and dereference to the effective
    target.
