### Enhancements in Version 8.51

Reference | Description
--- | ---
SM-98674 | Sentinel License Manager now supports client identity registration on a user's machine when the user click a provided link. The License Manager Service can parse and decode the URL to copy the identity string to the local INI file.
SM-128094 | Sentinel Admin API can now be used to obtain a C2V file or fingerprint file from a user's machine.

### Issues Resolved in Version 8.51

Reference | Description
--- | ---
SM-122150 | The License Manager would fail on machines with a CPU from before 2010.
SM-123325 | The recipient list of detaches was incomplete when working with secure storage. (The list is complete when working with trusted storage.) Note: This issue did not affect functionality - it only affected the user interface.
SM-123370 | Certain errors would occur in the detection of Parallels VMs.
SM-124009 SM-130468 | The PMType2 clone detection scheme did not work correctly under certain unusual circumstances.
SM-126115 | The Admin License Manager would always checks the idle timeout, while the Runtimeless API never checks it. As a result, when installing or uninstall the RTE, conflicting behavior might occur for an HL Driverless key. Now, if the logged-in Feature on the key is not enabled for network access, idle timeout is skipped.
SM-127056 | The listing in Admin Control Center of products with detachable features did not paginate correctly.
SM-128810 | For Sentinel Licensing API, when a call to hasp_login_scope() fails, the event is now logged with the related feature_id, as was already occuring with hasp_login(). Until now, the behavior for the two functions was inconsistent.
SM-130023 | Errors in DNS resolution with client identity are now handled better.
SM-130889 | The License Manager Service was not able to access a cloud license manager hosted by Google Cloud Platform with proxy settings.
SM-131117 | In Admin Control Center, automatic detach was not taking friendly names for Feature and Product names.
