* 🔧 Update sponsors badge, course bundle. PR [#3340](https://github.com/tiangolo/fastapi/pull/3340) by [@tiangolo](https://github.com/tiangolo).
* 🔧 Add new gold sponsor Jina 🎉. PR [#3291](https://github.com/tiangolo/fastapi/pull/3291) by [@tiangolo](https://github.com/tiangolo).

*   TensorFlow Lite has moved from contrib to core. This means that Python
    modules are under `tf.lite` and source code is now under `tensorflow/lite`
    rather than `tensorflow/contrib/lite`.
*   TensorFlow GPU binaries are now built against CUDA 10 and TensorRT 5.0.
*   Support for Python3.7 on all operating systems.
*   Moved NCCL to core.
