This section describes enhancements implemented and issues resolved in the last three major releases of Sentinel Run-time Environment.

The revision history for earlier versions of Sentinel Run-time Environment is available at: https://docs.sentinel.thalesgroup.com/ldk/LDKdocs/RTE_History/Default.htm

### Enhancements in Version 8.43

No enhancements are included in this release.

### Issues Resolved in Version 8.43

Reference | Description
--- | ---
SM-120179 | The zlib library has been upgraded to version 1.2.12.
SM-121566 | During installation of Run-time Environment 8.41 on a machine with an old CPU, installation would fail with a message similar to: Error when starting the Sentinel License Manager service with parameters 1280 0 0. This is an internal error.
SM-123325 | In Admin Control Center, the displayed recipient list of detached licenses was incomplete when the Sentinel License Manager worked with Secure Storage. This issue would not occur when working with Trusted Storage. This issue did not affect functionality of the License Manager.

### 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. >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

Reference | Description
--- | ---
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.

### Enhancements in Version 8.31

Reference | Description
--- | ---
SM-108300 | Admin Control Center help system now describes how to set a user name for the ACC administrator. Setting a user name helps to improve security for Admin Control Center. For details, open the Admin Control Center help. From the list of links at the bottom of the pages, click Configuration > Managing User Access to Admin License Manager Information > Setting a User Name for the ACC Administrator.

### Issues Resolved in Version 8.31

Reference | Description
--- | ---
SM-104739 | When the Windows user names includes non-unicode characters as in Korean and Chinese names, installing a rebranded RTE returns "EMSUrl.properties processing" error.
SM-102367 | In some cases, RTE installation would fail with error -536870329.

### Enhancements in Version 8.23

Reference | Description
--- | ---
SM-17686 | A customer can now detach one or more seats with concurrency from a cloud license server and install them on a machine with a client identity. Applications on remote machines in the same LAN can then consume seats from this machine. This enables customers to: > Set up second-level license servers. > Control the number of local hardware resources used by an application.

### Issues Resolved in Version 8.23

Reference | Description
--- | ---
SM-98723 | The License Manager would log each individual Feature request from other License Managers. This resulted in an excessive number of entries in the License Manager log file.
SM-99308 | When connecting with port 80, Login/Logout/Encrypt API calls to cloud SL keys installed on a cloud license server would cause repeated WSAECONNREFUSED and ESELECTTIMEDOUT errors on the client machine.

### Enhancements in Version 8.21

Reference | Description
--- | ---
| By default, the Run-time Environment is now installed without legacy drivers whenever possible. As a result, the RTE installation is more stable and reliable. For more information, see the description of legacy drivers in this document.
| Admin Control Center has been updated to keep it consistent with changes in the appearance of Sentinel LDK user interfaces and documents to match other Thales products.
| The Run-time Environment installer has been improved. Previously, completion of the upgrade of the Run-time Environment (hasplms.exe) was sometimes blocked if the existing Sentinel License Manager was locked by another process. With the installer for RTE 8.21, if this situation occurs, the user can now select one of these options: > Stop the process that is locking the Sentinel License Manager and then continue the Run-time Environment upgrade. >Restart the machine. The Run-time Environment upgrade continues immediately after the restart. > Cancel the upgrade.
SM-86274 | The License Manager now supports releasing an identity-based license on a remote machine. An end user who is assigned an identity-based license is typically granted the right to access that license from two or more machines, but only from a single machine at any given time. The user may face a situation in which they access their license from one machine (for example, their office machine) but fail to close the application's session. If they later attempt to access their license from a different machine (for example, their home machine), the login to the license will fail and return the status code HASP_IDENTITY_SHARING_VIOLATION. The protected application can provide users with the option to release their license from the original session and assign it to the new session.

### Issues Resolved in Version 8.21

Reference | Description
--- | ---
SM-91083 | A user of Admin Control Center was not able to clear the password for accessing or configuring the License Manager once a password has been set.
SM-93806 | Sentinel Admin API would return invalid XML when the Issue To field of client identities contains some special characters.
SM-93811 | When a user would attempt to rehost a license from RTE 8.1x to an RTE version lower than 8.11, the error 30 HASP_INV_SIG was returned.
SM-94573 | With cloud licensing, when opening a remote session, the session would be closed after 15 minutes if no hasp call was made on the session. This resolution fixes the keep-alive timeout.
SM-96073 | The License Manager would fail under certain circumstance when working with client identities.
SM-96715 | Memory leak while using identity sessions have been resolved.
SM-97123 | Firewall compatibility for identity communications has been improved.
