Dear Alibaba Cloud users:
To deliver a better access experience and more efficient interaction flow, Alibaba Cloud CAPTCHA 2.0 has completed a comprehensive upgrade for CAPTCHA 2.0 with the official launch of the V3 architecture.
This upgrade brings significant improvements in compatibility, usability, and performance. The new version offers simpler integration methods and a smoother user interaction experience, making it ideal for all new users and business scenarios.
Impact
This update only applies to users and scenarios integrating via the client V3 architecture. If you are still using the client V2 architecture, your existing services will remain unaffected and continue to operate as normal.
To upgrade from V2 to V3, you only need to update your client-side implementation. Our server-side is fully backward compatible, so no additional backend changes are required.
The WeChat mini program currently only supports access to the V2 architecture. It does not yet support V3.
Thank you for your continued trust and support.
