    build environment of the currently installed TensorFlow package, e.g. the
    NVIDIA CUDA and NVIDIA CuDNN versions used when TensorFlow was built.

### Profiler

*   Fix a subtle use-after-free issue in `XStatVisitor::RefValue()`.

### TPU Enhancements

*   Adds 3D mesh support in TPU configurations ops.
*   Added TPU code for `FTRL` with `multiply_linear_by_lr`.
