SIG Scalability has mostly focused on stability and deflaking our tests, investing into framework for writing scalability tests (ClusterLoader v2) with a goal to migrate all tests to it by the end of 2018 and on the work towards extending definition of Kubernetes scalability by providing more/better user-friendly SLIs/SLOs.

### SIG Scheduling

        deprecated in TF 2.2.

*   `tf.lite`:

    *   `tf.quantization.quantize_and_dequantize_v2` has been introduced, which
        updates the gradient definition for quantization which is outside the
        range to be 0. To simulate the V1 the behavior of
        `tf.quantization.quantize_and_dequantize(...)` use

#### **Custom Resources**

*   Validation of resources defined by a Custom Resource Definition (CRD) is now in beta ([#54647](https://github.com/kubernetes/kubernetes/pull/54647),[ @colemickens](https://github.com/colemickens))
