The first alpha of Couchbase Python Client 3.0 has been released, featuring a harmonized and revised API that shares advanced internals with its predecessor. The new version includes support for collections, synchronous durability, and automated provision of libcouchbase. It also introduces extensive type hints for improved discoverability and reliability. The SDK is available to download in pre-release alpha form and is compatible with Python 3, while supporting Python 2.7 for now due to its EOL status.
