# Enhancements and Issues Resolved in This Release

This section describes enhancements introduced and issues resolved in this release of the Sentinel LDK Run-time Environment.

### Enhancements in Version 8.41

Reference | Description
--- | ---
SM-97094 | You can now set an expiration date for client identities. This enables vendors to: >Easily manage trial by providing users with expiring identities that consume the same license. This removes the need to generate a new key and a new license for each trial. >Easily provide customers with an emergency CL license in case they face issues with their local HL or SL key. >Manage which users can access a concurrency license and for how long.
SM-111379 | The License Manager now supports the use of dynamic memory for SL AdminMode keys . To support this functionality, VLIB 8.41 or later must be deployed with the Run-time Environment.

### Issues Resolved in Version 8.41

SM-119586 | After connecting to a VPN, when you click Submit on the Access to Remote ACC panel, a false-positive warning similar to the following was sometimes displayed: "A duplicate License Manager ID exists on this server and on the server at address 10.42.49.253. This is typically caused by cloning a VM. Licenses on these two servers may be inaccessible"
SM-119327 | If no host is specified, AdminAPI uses "localhost" to connect to the License Manager. But in modern machines, localhost is resolved to "::1". This may not work because the IPv6 option may be disabled in the License Manager. AdminAPI now uses "127.0.0.1" instead of "::1".
SM-115393 | When the client identity is installed in Admin Control Center, and the License Manger received a detached license from a remote machine, a local API was affected by the local License Manager detachable configuration. However, the local License Manager should have only acted as the forwarder in this case.
