### Issues Resolved in Version 9.15

Reference | Description
--- | ---
SM-153766 | Given the following circumstances: 1.A proxy setting is placed in hasp_<vendorId>.ini along with a client identity. 2.The application calls hasp_transfer to detach a license from the cloud license server successfully. An error was returned when the application called hasp_update to apply the detached license.
SM-156906 | The process for installing a client identity on a user's machine using the provided URL would fail if a different identity with the same server already existed on the user's machine. Now a relevant message is displayed to notify the user of the conflict.
SM-156932 | The processid parameter in a session created by the REST API was not properly set in Admin API output. The parameter contained an unexpected 19-digit value instead of the expected value.
SM-158487 | When configuring a trusted client in Admin Control Center, it was not possible to specify a range of IP addresses.

### Enhancements in Version 9.14

Reference | Description
--- | ---
SM-147888 | Certain enhancements have been implemented for working with Sentinel LDK CL (Cloud Licensing) Service.

### Issues Resolved in Version 9.14

Reference | Description
--- | ---
SM-148071 | When using the hasp_transfer function in Sentinel Licensing API to transfer an SL key, hasp_transfer would generate the return code 50 (HASP_SCOPE_RESULTS_EMPTY) when attempting to detach the SL key from the source machine.
SM-148693 | The Sentinel Keys page in Sentinel Admin Control Center would not display if a key to be listed on the page contained a newline character in its "friendly" key name (in the <keydescription> field).

### Enhancements in Version 9.13

Reference | Description
--- | ---
SM-133552 | The login_scope function in Sentinel Licensing API can limit login to cloud licenses. Login can be limited to: >A cloud license >A license that originated from a cloud license >A license that is detached from a cloud license >A non-cloud network license The get_info function can return attributes that differentiate between these license types.
SM-134759 | The login_scope funtion in Sentinel Licensing API can specify that login should be limited to a specific key ID. The same call with the same key ID can also limit login to a license detached locally from that key. (Users typically have multiple auto-detached keys from different CL keys.)

### Issues Resolved in Version 9.13

Reference | Description
--- | ---
SM-145573 | In Sentinel Admin Control Center 9.12, if the user attempted to access Configuration > Client Identities > Add Client Identity > Help, the resulting help page was blank.
SM-143338 | The Diagnostics page in Admin Contol Center would display the operating system as Windows 10 on a Windows 11 machine.
SM-138618 | When using manual detach for a license in Admin Control Center, the user can specify an expiration date using day, month, and year fields, or they can select a date from a calendar. If the user selected a date from the calendar, the day, month, and year fields were not synchronized to the selected date, but the detach license would expire according to the values in the day, month and year fields.
SM-145002 SM-144828 | Resolved issues in access control when cloud licenses are accessed by a remote machine with a client identity using Sentinel Licensing REST API.
SM-145528 | Uploading an XML file for mapping Vendor ID, Products and Features to Admin Control Center required much more time than was required in earlier versions of Admin Control Center.

### Enhancements in Version 9.12

Reference | Description
--- | ---
SM-137293 | Sentinel LDK Run-time Environment and protected applications are both supported under Windows 11 ARM 22H2.
SM-137232 | Maximum idle timeout for sessions has been increased to 72 hours.
SM-134021 | Access to Sentinel Admin API can now be restricted so that it is only available for users from the local network. This can be enforced using firewall rules. Administrator-level requests would be allowed only on a specific port or network interface (or both).
SM-105690 | The License Manager now supports the new Sentinel Licensing REST API.
SM-104883 | The License Manager now accepts a V2C file to clear the the time-tampered status for an SL key.

### Issues Resolved in Version 9.12

Reference | Description
--- | ---
SM-134020 | Under certain circumstances, UDP packets may be lost. Broadcast search now repeats the UDP transmission multiple times to overcome the loss of UDP packets.
SM-136775 | The License Manager was not able to keep track of more than 2,000 clients' LM identifiers. This could result in incomplete information when listing detached licenses in the server Admin Control Center pages. The limitation of 2,000 LM identifiers has been removed.
SM-139869 | Previously, when a proxy was configured in ACC, the LM would attempt to resolve DNS names, even if they were not resolvable in the local network. This resulted in connection failures. Now, when a proxy is defined in ACC, the LM no longer attempts to resolve DNS names. Instead, it allows the proxy to handle DNS resolution.
SM-139963 | When a seat was detached from a license with no vendor name defined, the H2R file would contain invalid information in the vendor name field.
SM-140200 | Sentinel Admin API was not able to retrieve client identity information when the client identity was defined with multiple key IDs and admin_get was called using a specific key ID in the scope.
SM-141007 | If the session username contains the "&" character, the GetInfo function would report the value in the XML structure as specified, resulting in an invalid XML file. For example: `<session username="G&D" />` Now, the character is reported back as an XML entity. For example: `<session username="G&amp;D" />`

### Enhancements in Version 8.53

Reference | Description
--- | ---
SM-134244 | Sentinel LDK Run-time Environment and protected applications are both supported under Windows 10 22H2.

### Issues Resolved in Version 8.53

Reference | Description
--- | ---
SM-134170 | Given the following circumstances: 1.The vendor asssigned multiple key IDs in the Limit to Key ID field for a client identity on the license server. 2.The vendor sends the identity string for the client identity to the licensed user. After the licensed user applies the identity string on their machine, only one key ID is shown on the user's machine.

### 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.
