Change Notes

HSS.117 Setting a device name that is in use causes an incorrect response

When using the device name feature introduced in 1.4.0.2, if a device name was set that was already in use or not yet released by the host then an incorrect response would be sent by Jubilant to the host. This has been resolved in this release.

Please note: Jubilant now responds to a device name being in use by showing a client message and disconnecting the session. If you see this message, please set a new device name via the settings icon on the tile or, if you have just disconnected and wish to re-use the same device name, wait until the host has released it.

WTC.481 When a display name is not set display the definition name on the connection tiles

If a host definition did not have a display name set then the connection tile would not show any text. As of this release the definition name is displayed in the case that no display name is set.

WTC.485 The Program Messages screen in 5250 can display a FieldControlWords undefined error

If a user interacted with the Program Messages screen in 5250 in any way other than just pressing Enter then the client would display a FieldControlWords undefined error. This issue has been resolved in this release.

WTC.486 When no screen is returned the keyboard and the cursor should not be active

If an issue with connecting to the host resulted in no screen being returned then a blank screen was displayed. The keyboard and cursor where active on this screen and interacting with them could cause an error to be displayed. As of this release the screen now displays 'Awaiting Screen' and the keyboard and cursor are inactive.

WTC.488 Single character 5250 auto-enter fields can cause a client error

Interacting with a single character auto-enter field on a 5250 screen could cause the client to display an error. This issue has been resolved in this release.

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.
