### Trains 0.13.3

**Features and Bug Fixes**

* Add a binding for `tensorboard.summarywriter.addscalars`
* Add the `tensorboard_single_series_per_graph` method, which supports separate plots for each TensorBoard scalar.
* Add the `Task.set_base_docker` and `Task.get_base_docker` methods for the base Docker image used by **Trains Agent**.
* Add support for the standard OS environment variables to obtain default credentials for:
  * AWS: `AWS_ACCESS_KEY_ID`, `AWS_SECRET_ACCESS_KEY`, and `AWS_DEFAULT_REGION`.
  * Azure Storage: `AZURE_STORAGE_ACCOUNT` and `AZURE_STORAGE_KEY`.
  * Google Cloud Storage: `GOOGLE_APPLICATION_CREDENTIALS`.
    
* Add the `Task.get_parameters_as_dict` and `Task.set_parameters_as_dict` methods supporting get / set of parameters from referenced Tasks (use the `Task.get_task` to get a reference).
* Make sure `Task.connect` always returns the connected instance passed to it.
* `tensorflow_gpu` takes precedence over `tensorflow` when Trains detects installed packages to record experiment dependencies.
* Remove title and series naming restrictions (allow `$` and `.`) when reporting metrics.
* Fix incorrect printouts in initialization wizard and upgrade notifications.
* Fix debug images URL for uploaded files with `%` in their name.

  using the `Logger.report_image.params.url` parameter.
* Add support for Git repositories without a `.git` suffix, for example Azure Repos.
* Improve conda support.
* Improve hyperparameters [argparser](https://docs.python.org/3/library/argparse.html) integration.

* Add support for PyTorch `.pt` model files.
* Calculate data-audit artifact uniqueness by user-criteria ([GitHub Issue #45](https://github.com/allegroai/trains/issues/45)).
