Multi-backend Keras has a new repo: keras-team/keras.
Open any issues / PRs there. keras-team/keras-core is no longer in use.
Keras Core was the codename of the multi-backend Keras project throughout its initial development
(April 2023 - July 2023) and its public beta test (July 2023 - September 2023). Now, Keras Core
is gearing up to become Keras 3, to be released under the keras name. As such, we've moved development
back to keras-team/keras.
Meanwhile, the legacy tf.keras codebase is now available at
keras-team/tf-keras.

history has been fully preserved: the new commits have been reapplied on top of the old git tree.
