v4.5.0-rc

Highlights

• Improved handling of pre-authorized requests:
  • During long running asyncronous download operations (i.e. syncing a folder with many files),
    some pre-authorized URLs were expiring before they were used to download the file. This
    change will now check the expiration datetime of the URL before using it to download the file.
    If the URL is expired it will be refreshed.
• Added support for pandas.read_csv key word arguments:
  • Added support for all pandas.read_csv key word arguments to the asDataFrame method of the CsvFileTable class.
  • This enables custom handling of how to handle missing values and default values when reading a Synapse table to a pandas DataFrame.
