3.20.4

Common Cryptography Library

The config entry [general] useCommonCryptography> enables the use of the new cryptography library. For compatibility reasons, the previous functionality remains preset.

Customers can now use the modernized crypt library to encrypt and decrypt CTRL functions, which further increases security.

OPC UA client

When establishing a connection to the server, the OPC UA client can now be configured to ignore an expired server certificate. This security-critical implementation is only meant to ensure productive usage, e.g. if a customer is unable to update/renew their certificate on time, and it is not recommended to set it permanently.

CTRL Script editor

• Opening the script editor for a panel now also shows the list of functions available within the panel scope, which makes it faster & easier to jump to the desired location.
• The main editor window received the additional File menu action Save All. This will save all open scripts at once. Additionally, each script window tab shows a Save Icon to indicate unsaved changes

Alarm Row (AESRow)

For faster handling, the Alarm row received the functionality to multi-select several lines and acknowledge the selected alarms with a single user-interaction, therefore saving operation time. For compatibility reasons, this functionality is not set by default and needs to be activated with the config entry [ui] aesRowMultipleSelection = 1

Proxmox

With this patch we now also support Proxmox as an additional and cost-effective virtualization platform alongside the already supported VMWare software modules. Please check the specific documentation page for details.

This platform will also be supported for WinCC OA V3.19 with the next patch.

Estimation of disk space panel

This panel, which allows the user to calculate estimates of the required disk space for different WinCC OA archiving options, received a usability update.

Video Add-On

The WinCC OA Video Add-On now supports the new Axis devices Joystick TU9002 and Keypad TU9003. This does however not apply to the emergency client (Video Workstation).
