# Release 2.20.0

## TensorFlow

### Breaking Changes

* The `tensorflow-io-gcs-filesystem` package is now optional, due its uncertain, and limited support. To install it alongside `tensorflow`, run `pip install "tensorflow[gcs-filesystem]"`.

### Major Features and Improvements

* `tf.data`

* Fixes a flaw (CVE-2019-11253) in json/yaml decoding where large or malformed documents could consume excessive server resources. Request bodies for normal API requests (create/delete/update/patch operations of regular resources) are now limited to 3MB. ([#83261](https://github.com/kubernetes/kubernetes/pull/83261), [@liggitt](https://github.com/liggitt))
* Update to go 1.12.10 ([#83139](https://github.com/kubernetes/kubernetes/pull/83139), [@cblecker](https://github.com/cblecker))

Implementation restriction: Although numeric constants have arbitrary
precision in the language, a compiler may implement them using an
internal representation with limited precision.  That said, every
implementation must:
