Version 1.10.0-rc0

Major Features and Improvements

• Saved tuner results in pandas records formatted JSON.
• TFX Transform now supports tf.SequenceExample natively. The native path can be activated by providing TensorRepresentations in the Schema.
• TFX Transform now supports reading raw and materializing transformed data in Apache Parquet format.
• ExampleDiff outputs statistics on the matching process, and optional counts of paired feature values.

Bug Fixes and Other Changes

• Type hint on BaseComponent.inputs and BaseComponent.outputs corrected to be Channel subclasses.
• Added input_optional parameter to ChannelParameter. This allows component authors to declare that even if a channel is optional, if it is provided during pipeline definition time, then it must have resolved inputs during run time.
• Allow latest apache-airflow 2.x versions.
• Moved tflite-support related dependencies from [examples] to a separate [tflite-support] extra.
• Output artifacts from multiple invocations of the same component are given unique names, avoiding duplication errors, especially in the InteractiveContext.
