* Fix: 500 Error without message when micro-batch enabled 857
* Fix: port conflict with --debug flag 858
* Permission issue while building docker image for BentoService created under Windows OS 851

What's New?

* Support Debian-slim docker images for containerizing model server, 822 by jackyzha0. User can choose to use :
python
env(
auto_pip_dependencies=True,
docker_base_image="bentoml/model-server:0.8.2-slim-py37"
)


* New `bentoml retrieve` command for downloading saved bundle from remote YataiService model registry, 810 by iancoffey
bash
bentoml retrieve ModelServe:20200610145522_D08399 --target_dir /tmp/modelserve


* Added `--print-location` option to `bentoml get` command to print the saved path, 825 by jackyzha0
bash
$ bentoml get IrisClassifier:20200625114130_F3480B --print-location
/Users/chaoyu/bentoml/repository/IrisClassifier/20200625114130_F3480B


* Support Dataframe input JSON format orient parameter. DataframeInput now supports all pandas JSON orient options: records, columns, values split, index. 809 815, by bojiang

For example, with `orient="records"`:
python
api(input=DataframeInput(orient="records"))
def predict(self, df):
...

The API endpoint will be expecting HTTP request with JSON payload in the following format:
json
[{"col 1":"a","col 2":"b"},{"col 1":"c","col 2":"d"}]

Or with `orient="index"`:
json
'{"row 1":{"col 1":"a","col 2":"b"},"row 2":{"col 1":"c","col 2":"d"}}'

See pandas's documentation on the orient option of to_json/from_json function for more detail: https://pandas.pydata.org/pandas-docs/stable/reference/api/pandas.DataFrame.to_json.html

* Support Azure Functions deployment (beta). A new fully automated cloud deployment option that BentoML provides in addition to AWS SageMaker and AWS Lambda. See usage documentation here: https://docs.bentoml.org/en/latest/deployment/azure_functions.html

What's New?

* Service API Input/Output adapter 783 784 789, by bojiang
* A new API for defining service input and output data types and configs
* The new `InputAdapter` is essentially the `API Handler` concept in BentoML prior to version 0.8.x release
* The old `API Handler` syntax is being deprecated, it will continue to be supported until version 1.0
* The main motivation for this change, is to enable us to build features such as new API output types(such as file/image as service output), add gRPC support, better OpenAPI support, and more performance optimizations in online serving down the line

* Model server docker image build improvements 761
* Reduced docker build time by using a pre-built BentoML model server docker image as the base image
* Removed the dependency on `apt-get` and `conda` from the custom docker base image
* Added alpine based docker image for model server deployment

* Improved Image Input handling:
* Add micro-batching support for ImageInput (former ImageHandler) 717, by bojiang
* Add support for using a list of images as input from CLI prediction run 731, by bojiang
* In the new Input Adapter API introduced in 0.8.0, the `LegacyImageInput` is identical to the previous `ImageHandler`
* The new `ImageInput` works only for single image input, unlike the old `ImageHandler`
* For users using the old `ImageHandler`, we recommend migrating to the new `ImageInput` if it is only used to handle single image input
* For users using `ImageHanlder` for multiple images input, wait until the `MultiImageInput` is added, which will be a separate input adapter type

* Added CORS support for AWS Lambda serving 752, by omrihar
* Added JsonArtifact for storing configuration and JsonSerializable data 746, by lemontheme

Bug Fixes & Improvements:
* Fixed Sagemaker deployment `ModuleNotFounderError` due to wrong gevent version 785 by flosincapite
* Fixed SpacyModelArtifact not exposed in `bentoml.artifacts` 782, by docteurZ
* Fixed errors when inheriting handler 767, by bojiang
* Removed `future` statements for py2 support, 756, by jjmachan
* Fixed bundled_pip_dependencies installation on AWS Lambda deployment 794
* Removed `aws.region` config, use AWS CLI's own config instead 740
* Fixed SageMaker deployment CLI: delete deployment with namespace specified 741
* Removed `pandas` from BentoML dependencies list, it is only required when using DataframeInput 738
