12.21.0 (2024-07-17)

Features Added

• Stable release of features from 12.21.0b1
• Added new chars keyword to the StorageStreamDownloader.read method to support reading an arbitrary number of
  characters from the stream rather than bytes. This can only be used when encoding is specified on download_blob
  but can help prevent decoding errors in certain scenarios.
