Victoria Series Release Notes

11.0.0-7

Upgrade Notes

• Upgrade one of the storage drivers, the Mongo driver with new version of PyMongo. PyMongo has been updated to 4.0.0, there are some changes which are not supported in the 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.
