Change Notes

WTC.497 Update NPM packages to resolve security issues

The client NPM packages have been updated to resolve a number of security issues

MCC.40 Fix incorrect button state

Under certain conditions, buttons in the management console could fail to reflect the true state of the underlying data. This has been resolved in this release.

WTA.94 Make the mismatched screen error message configurable

It is now possible to turn off the warning message shown when a send action is sent to the hub for an out-of-date screen.

It is also possible to allow the sending of the AID key if there are no field changes.

Messaging

By default, the message will be shown. To disable the message:

  1. Open the management console
  2. Click on Global Settings in the Web Terminal section
  3. WITHOUT making any changes, click the Save button, this will save the latest version of the file which includes the new settings
  4. Open WebTerminalSettings.json in C:\ProgramData\Flynet\Jubilant\WebTerminal\web\hub in a suitable editor (e.g. VS Code).
  5. At the bottom of the file there is a new section titled SendAction, in that section set the value of SuppressClientMessage to true.
  6. Save the file.
  7. Run iisreset from an administrator command prompt. Note that this will disconnect any users currently connected via the Jubilant server.

If you have multiple Jubilant servers, you will need make this change on all servers.

We recommend that you make a backup of WebTerminalSettings.json before you make any changes.

Allow SendAction with Screen Mismatch if No Field Changes

The new SendAction section also contains a setting which allows send actions which do not alter any fields to be allowed through despite a screen mismatch. This setting is enabled by default. To disable this feature, set AllowMismatchedSendActionWithZeroFields to false.

Settings Example and Defaults

C:\ProgramData\Flynet\Jubilant\WebTerminal\web\hub\WebTerminalSettings.json.

"SendAction": {
  "AllowMismatchedSendActionWithZeroFields": true,
  "SuppressClientMessage": false
}

WTC.429 On-screen keyboard on small screen devices

On small screen devices the on-screen keyboard can be difficult to use. The work around is to define a new keyboard layout and select it via the settings.

WTC.492 Screen size calculations are slightly off

Under certain, rare, circumstances an issue with screen size calculations can cause the top line of the screen to be partly or wholly obscured. This usually occurs when the host changes the screen resolution. The work around is either to turn on stretch to fit in the settings menu or to resize the browser window, changing its width until the top line is visible.
