Victoria Series Release Notes


Upgrade Notes

  • Upgrade one of storage drivers, mongo driver with new version of pymongo. Pymongo has been updated to 4.0.0, there are some changes which are not supported in new version: 1. Collection.count and Cursor.count is removed. 2. Collection.ensure_index is removed. 3. Collection.__bool__ raises NotImplementedError. 4. Should use Binary.from_uuid to handle the UUID object. Those changes need to upgrade the mongo driver’s code to work well.


New Features

  • To enhance the security of messaging service, the queue in Zaqar supports to encrypt messages before storing them into storage backends, also could support to decrypt messages when those are claimed by consumer. To enable this feature, user just need to take “_enable_encrypt_messages=True” when creating queue. AES-256 is used as the default of encryption algorithm and encryption key is configurable in the zaqar.conf.
