Checksum Info:
The checksum allows to check whether the update file is the file provided by SEH before installation. 

A check can simply be done with e.g. the „shasum“ under macOS/Linux, „sha256sum“ under Linux or under Windows with the „ certutil“ tool, or in Powershell with the "Get-FileHash“ tool. The comparison can then be done manually (the hash values differ dramatically with a slight change) or with the -c option of the checksum commands in one step (see the following example for macOS/Linux):

Example macOS/Linux:
shasum -a 256 [FILENAME]

➔ echo 'bde49684d37e507cf6a85ee0af837359c27dcced94f0736136aa0a0f638d0875 *d-sys-uds-20.2.8.bin' | shasum -c
d-sys-uds-20.2.8.bin: OK


Example Windows:
Windows command prompt:
CertUtil -hashfile [FILENAME] SHA256
C:>certutil -hashfile d-sys-uds-20.2.8.bin SHA256
SHA256 hash of d-sys-uds-20.2.8.bin:
bde49684d37e507cf6a85ee0af837359c27dcced94f0736136aa0a0f638d0875
CertUtil: -hashfile command completed successfully.


Release Notes:
---------------------------------------------------------------------------
New Software Version:   			20.2.8
New Features/Changes/Fixes: since 	20.2.6

Important Upgrade Note:
#######################
Backup your current settings before upgrading.
Only a parameter backup ensures all configurations are preserved if you need to downgrade. 

1) General:
-----------
- OpenSSL LTS Version 3.5.4
- Contains  fixes and improvements
- Backend improvements for enhanced stability, device compatibility, and protocol handling.
 
 2) Fixes/Improvements:
----------------------
- [Improved] HID/MSD detection is now visually indicated in the Control Center. The corresponding checkboxes are highlighted with a border if a connected USB device is detected as a Human Interface Device (HID) or Mass Storage Device (MSD).
- [Fixed] HID/MSD blocking settings now take effect immediately after saving and no longer require a restart of the UTN server.
- [Fixed] USB port information is now included for all recipients of USB device status change notifications. Previously, only the first email recipient received the detailed USB port information.
- [Improved] The Control Center security warning has been updated for devices upgraded from an earlier software version. If existing passwords do not meet the current password requirements, the warning now clearly indicates that the passwords must be updated. This helps clarify cases where passwords are already set but no longer comply with the current security policy.
- [Fixed] The Control Center now displays an error message when saving a USB Manager password that does not meet the current password requirements. Previously, the change was reported as successful although the password was not accepted and the parameter remained unchanged.
- [Fixed] [dongleserver ProMAX/INU-100] Access protection for sensitive files stored on the SD card has been improved. Previously, after removing and reinserting the SD card, certain sensitive files could become accessible via the internal file browser to an authenticated administrator. These files are now protected as intended.
- [Fixed] [INU-50] Resolved an issue where devices could only be activated once. A second activation could cause the device to repeatedly switch between activated and deactivated states.

3) New Devices:
