# Release 2.5.0

## Major Features and Improvements

*   Support for Python3.9 has been added.
*   `tf.data`:
    *   `tf.data` service now supports strict round-robin reads, which is useful
        for synchronous training workloads where example sizes vary. With strict
        round robin reads, users can guarantee that consumers get similar-sized
        examples in the same step.

   * <p>Example usage:
   *
   * {@snippet :
   * // Fall back to a secondary input stream in case of IOException.
   * ClosingFuture<InputStream> inputFuture =
   *     firstInputFuture.catchingAsync(
   *         IOException.class, (closer, x) -> secondaryInputStreamClosingFuture(), executor);
   * }

* HTTP transport now uses `context.Context` to cancel dial operations. k8s.io/client-go/transport/Config struct has been updated to accept a function with a `context.Context` parameter. This is a breaking change if you use this field in your code. ([#60012](https://github.com/kubernetes/kubernetes/pull/60012), [@ash2k](https://github.com/ash2k))

- Added a method `StreamWithContext` to `remotecommand.Executor` to support cancelable SPDY executor stream. ([#103177](https://github.com/kubernetes/kubernetes/pull/103177), [@arkbriar](https://github.com/arkbriar))

- Added a new option `strict-cpu-reservation` for CPU Manager static policy. When this option is enabled, CPU cores in `reservedSystemCPUs` will be strictly used for system daemons and interrupt processing no longer available for any workload. ([#130290](https://github.com/k...
