**Breaking Changes:**
* `Policy` object has been moved from `cbc_sdk.endpoint_standard` to `cbc_sdk.platform`, as it now uses the new Policy Services API rather than the old APIs through Integration Services.
* **N.B.:** This change means that you must use a custom API key with permissions under `org.policies` to manage policies, rather than an older "API key."
* To enable time to update integration logic, the `cbc_sdk.endpoint_standard Policy` object may still be imported from the old package, and supports operations that are backwards-compatible with the old one.
* When developing a new integration, or updating an existing one `cbc_sdk.platform` should be used. There is a utility class `PolicyBuilder`, and as features are added to the Carbon Black Cloud, they will be added to this module.
* Official support for Python 3.6 has been dropped, since that version is now end-of-life. Added explicit testing support for Python versions 3.9 and 3.10. **N.B.:** End users should update their Python version to 3.7.x or greater.
New Features:
* Credentials handler now supports OAuth tokens.
* Added support for querying a single `Report` from a `Feed`.

* Increased the asynchronous query thread pool to 3 threads by default.
* Required version of `lxml` is now 4.9.1.

Bug Fixes:
* Added `max_rows` to USB device query, fixing pagination.
* Fixed an off-by-one error in Alerts Search resulting un duplicate alerts showing up in results.
* Fixed an error in alert faceting operations due to sending excess input to the server.
Documentation:
* Watchlists, Feeds, and Reports guide has been updated with additional clarification and examples.
* Updated description for some `Device` fields that are never populated.
* Additional sensor states added to `Device` documentation.
* Fixed the description of `BaseAlertSearchQuery.set_types` so that it mentions all valid alert types.
* Threat intelligence example has been deprecated.
