We strongly recommend that you migrate your KCL applications using version 1.x to the latest KCL version before January 30, 2026. To find the latest KCL version, see Amazon Kinesis Client Library page on GitHub. For information about the latest KCL versions, see Use Kinesis Client Library. For information about migrating from KCL 1.x to KCL 3.x, see Migrating from KCL 1.x to KCL 3.x.
