Release 4.1.0

Improvements/fixes
Query point encoders for Deep GP models (#873)

Full Changelog: v4.0.1...v4.1.0

Release 4.0.1

Improvements/fixes
Don't create additional feature when one-hot-encoding two-value categories (#869)
Support and test against Tensorflow 2.16 (#858)

Note that (like tensorflow-probability and GPflow) Trieste uses Keras 2. Since TF 2.16 defaults to using Keras 3, tf.keras (and Keras optimizers such as Adam) must now be imported from the tf_keras package instead. Alternatively, you can import tf_keras from the gpflow.keras module, which will automatically select the right source depending on which version of TF is installed.

v4.0.0

Breaking changes
This release includes a minor breaking change:

As part of #864, a number of built in model classes such as GaussianProcessRegression and DeepEnsembleModel have been updated to support optional query point encoders. This involved moving the implementation of public methods such as predict to new internal methods called predict_encoded etc that work on the encoded query points. Any user-defined class that overrode the public methods should therefore switch to overriding the *_encoded internal methods instead.
