 # Changelog

+### Announcement on March 13, 2025
+Amazon Kinesis Client Library (KCL) 1.x will reach end-of-support on January 30, 2026. Accordingly, these versions will enter maintenance mode on April 17, 2025. During maintenance mode, AWS will provide updates only for critical bug fixes and security issues. Major versions in maintenance mode will not receive updates for new features or feature enhancements. If you’re using KCL 1.x, we recommend migrating to the latest versions. When migrating from KCL 1.x to 3.x, you will need to update interfaces and security credential providers in your application.
