Bigflow

*Broken!* – DAG builder produces DAGs incompatible with (airflow 1.x + composer 1.x). Fixed in 1.5.2.

Fixed

* Composer 2.0 support – using `composer-user-workloads` namespace inside generated DAGs if running on Composer 2.X, to fix the problem with inheriting the Composer SA

Fixed

* Setting grpcio-status as <=1.48.2 to avoid problems with pip-compile on protobuf package
* changing docker image caching implementation – using BUILDKIT_INLINE_CACHE=1 only if cache properties are set
* always installing typing-extensions>=3.7 to avoid clashes

Removed

* Deprecated `log` and `dataproc` extras

Added

* The `base_frozen` extras with frozen base requirements
* More type hints
* Making exporting image to tar as optional

Fixed

* `bf build` arguments validation
* fixed broken MarkupSafe package version

Added

* Optional support for 'pytest' as testing framework
* Labels support for datasets and tables in DatasetConfig and DatasetManager

Added

* Check if docker image was pushed before deploying airflow dags

Fixed

* Propagate 'env' to bigflow jobs
* Automatically create and push `:latest` docker tag

Changed

* Changes in building toolchain - optimizes, better logging, optional setup.py
