TFX 1.16.0 Release

Major Features and Improvements

• N/A

Breaking Changes

• Placeholder.__format__() is now disallowed, so you cannot use placeholders
  in f-strings and str.format() calls anymore. If you get an error from this,
  most likely you discovered a bug and should not use an f-string in the first
  place. If it is truly your intention to print the placeholder (not its
  resolved value) for debugging purposes, use repr() or !r instead.
• Drop supports for the Estimator API.

For Component Authors

Deprecations

• KubeflowDagRunner (KFP v1 SDK) is deprecated. Use KubeflowV2DagRunner (KFP v2 pipeline spec) instead.
• Since Estimators will no longer be available in TensorFlow 2.16 and later versions, we have deprecated examples and templates that use them. We encourage you to explore Keras as a more modern and flexible high-level API for building and training models in TensorFlow.
