Hi.
Actually they are not 'replaced' but playmaker has now standard ui action,
Both can be used.
The uGuiGetText and uGuiSetText are not in that package (these where probably made before the package was planned/set up) and indeed not on the Ecosystem.
But i took them and placed them in a package so you can get them from the attachment below.
If you don't have many 'get/set text' action used, i would suggest to swap them with the ones from the package, or the official ones if you upgraded to 1.9+
