-    +  Dataset: fixed dataset download failure if data path containing unicode characters
-    +  Dataset: improved dataset mount caching mechanism to respect the minimum disk space requirement in Azure Machine Learning Compute, which avoids making the node unusable and causing the job to be canceled
     + Added user_managed flag in RSection which indicates whether the environment is managed by user or by AzureML.
-    + Dataset: we add an index for the timeseries column when you access a timeseries dataset as a pandas dataframes, which is used to speed up access to timeseries based data access.  Previously, the index was given the same name as the timestamp column, confusing users about which is the actual timestamp column and which is the index. We now don't give any specific name to the index since it should not be used as a column.

+    + Added support for loading ServicePrincipal from environment variables: AZUREML_SERVICE_PRINCIPAL_ID, AZUREML_SERVICE_PRINCIPAL_TENANT_ID, and AZUREML_SERVICE_PRINCIPAL_PASSWORD
     + Introduced a new parameter `support_multi_line` to `Dataset.Tabular.from_delimited_files`: By default (`support_multi_line=False`), all line breaks, including those in quoted field values, will be interpreted as a record break. Reading data this way is faster and more optimized for parallel execution on multiple CPU cores. However, it may result in silently producing more records with misaligned field values. This should be set to `True` when the delimited files are known to contain quoted line breaks.
     + Added the ability to register ADLS Gen2 in the Azure Machine Learning CLI
     + Renamed parameter 'fine_grain_timestamp' to 'timestamp' and parameter 'coarse_grain_timestamp' to 'partition_timestamp' for the with_timestamp_columns() method in TabularDataset to better reflect the usage of the parameters.
