* TensorFlow has been validated on Windows Subsystem for Linux 2 (aka WSL 2) for both GPUs and CPUs.
* Due to security issues (see section below), all boosted trees code has been deprecated. Users should switch to [TensorFlow Decision Forests](https://github.com/tensorflow/decision-forests). TF's boosted trees code will be eliminated before the branch cut for TF 2.9 and will no longer be present since that release.
