# Release 2.11.0

## Breaking Changes
*   `tf.keras.optimizers.Optimizer` now points to the new Keras optimizer, and
    old optimizers have moved to the `tf.keras.optimizers.legacy` namespace.
    If you find your workflow failing due to this change,
    you may be facing one of the following issues:

    *   **Checkpoint loading failure.** The new optimizer handles optimizer

For backward compatibility with the V1 format, this Op currently allows
restoring from a V1 checkpoint as well:
  - This Op first attempts to find the V2 index file pointed to by "prefix", and
    if found proceed to read it as a V2 checkpoint;
  - Otherwise the V1 read path is invoked.
Relying on this behavior is not recommended, as the ability to fall back to read
