# Lynx 1.7.5 Release Notes

> [!NOTE]
> Release Summary
> 
> Lynx 1.7.5 introduces easier password management for administrators, improves performance when working with large ProxCard enrollments, corrects domain validation behavior, restores sorting in the Prox Cards view, and includes security and platform updates to improve reliability and supportability.

### Prerequisites

Before installing Lynx 1.7.5, please ensure that the target system meets the following requirements:

- Windows Server 2019 or Windows Server 2022 (physical or virtual machine).
- The server on which Lynx 1.7.5 will be installed must be joined to the Active Directory domain that contains the users who will use the solution.
- A valid SSL certificate. The certificate can be issued by a public certificate authority or an internal authority such as Windows Certificate Services.
- Microsoft .NET Framework 4.8 or greater is installed.
- A valid license key is available from Identity Automation.
- **(Optional)** Microsoft SQL Server 2019 (any edition). SQL Server can be installed on the same machine as the Lynx Server software or on a different machine.
- **(Optional)** If Lynx will be used with Identity Automation's ExactAccess (XA) product, Lynx must be installed on the same computer as XA Server. In this configuration, a Microsoft SQL Server instance must be used.

For enterprise deployments, Identity Automation recommends using a high-availability SQL Server environment. Choose a SQL Server edition that supports high availability if that capability is required in your environment.

### New Features and Enhancements

| **Ticket Number** | **Description** |
| --- | --- |
| HEALTH-1830 | Administrators can now reset a user’s ProxCard password directly from the Lynx admin web interface. This removes the need for manual database work and makes it faster and easier for support teams to help users regain access. |
| HEALTH-1645 | Lynx now runs on Microsoft .NET Framework 4.8, improving long-term support, security, and compatibility with current Windows environments and supporting components. |

### Bugs Fixed

| **Ticket Number** | **Description** |
| --- | --- |
| HEALTH-1440 | Security-related issues identified in the Lynx application have been resolved to improve the overall protection and stability of the product. |
| HEALTH-1789 | Improved the ProxCard management experience in large environments. Customers with a high number of enrolled cards should no longer experience long browser freezes when opening or searching the ProxCard page. |
| HEALTH-1818 | Resolved an issue where some valid Active Directory domains could appear unreachable in Lynx settings, even though they were available and working correctly. Domain validation now behaves more accurately for affected environments. |
| HEALTH-1842 | Fixed an issue in the Prox Cards section where sorting by columns such as card count or username did not work as expected. Administrators can now sort enrolled users normally. |

### Database Update Instructions

Lynx 1.7.5 can be configured to use an embedded database or a Microsoft SQL Server database. If you are using the embedded database, no further action is required. If you are using a Microsoft SQL Server database and upgrading from Lynx 1.5.0, you must upgrade the database to support Lynx 1.7.5.

1. After installing or upgrading to Lynx 1.7.5, open the Windows Services application and find the `HealthCast Lynx` service.
2. Stop the `HealthCast Lynx` service.
3. Open the service properties.
4. Select the **Log On** tab.
5. Select **This account** and enter credentials for an account that has read and write privileges to the Lynx database on SQL Server.
6. Click **OK**.
7. Open SQL Server Management Studio.
8. Open the file `C:\Program Files (x86)\HealthCast\Lynx\CreateDb.sql`.
9. In the file, change the top line from use [YOUR-DATABASE-NAME-HERE] to the correct Lynx database name, such as `use [Lynx]`.
10. Run the `CreateDb.sql` file.
11. You may see errors indicating certain objects already exist. These can be safely ignored.
12. If you are upgrading from Lynx 1.7.2 or an older version, also run `UpgradeDb.sql` after replacing `[YOUR-DATABASE-NAME-HERE]` with the correct database name.
13. Start the `HealthCast Lynx` service again.
14. The database update is now complete.

> [!WARNING]
> Important
> 
> Lynx 1.7.5 requires Microsoft .NET Framework 4.8. Ensure .NET Framework 4.8 is installed before upgrading. Windows Server 2019 and Windows Server 2022 include this version by default.
