 #### Bugs Fixed
 * Fixed regression with handling of v1 legacy containers when passing `{}` as a partition key. `{}` and `NonePartitionKeyValue` now both resolve to the `Undefined` effective partition key. See [PR 48422](https://github.com/Azure/azure-sdk-for-python/pull/48422)
 * Fixed the same `TypeError` on system key (migrated) containers, where a missing partition key value resolves to `_Empty` instead of `Undefined`. It now maps to the minimum effective partition key. See [PR 48422](https://github.com/Azure/azure-sdk-for-python/pull/48422)
