Welcome to Microsoft Q&A, thanks for posting your query.
Microsoft does not provide specific end-of-support dates for individual versions of client libraries such as Azure.Storage.Blobs 12.7.1. Instead, these libraries are managed according to Microsoft's Azure SDK lifecycle policy. Under this policy, libraries are supported during their active development phase and continue to receive support for 12 months after transitioning to the maintenance-only phase. They generally follow a policy of encouraging users to upgrade to newer versions as older ones may become deprecated.
After a period, the major version enters a maintenance phase, during which only critical updates and security patches are provided. It's advisable to use the latest version to benefit from new features, improvements, and security updates.
