Deprecation should be interpreted as fair warning that a specific version or feature is scheduled for discontinuation and will result in a breaking change for an existing implementation.

We strongly urge developers to proactively update their code in response to this notice. Once a feature or version reaches its 'sunset' phase, it will be officially retired and no longer accessible.

Please plan your development activities accordingly to ensure a smooth transition. If you have any questions, please reach out to your customer success account representative.
