IBM COS SDK Core for Python

ibm-cos-sdk-core provides the low-level, data-driven core functionality for the IBM Cloud Object Storage (COS) SDK for Python. It is based on `botocore` and exposes similar low-level client interfaces. The current version is 2.16.1. It has a moderate release cadence, with several patch and minor releases per year, often aligning with `botocore` updates and adding new COS features.
