[Pharo-project] Loading OmniBrowser in 1.3 Core

I've already loaded AST and RB in a Core 1.3 #13299, how do you load OmniBrowser with Shout support? I've evaluated without success: Gofer new squeaksource: 'PharoOB'; package: 'ConfigurationOfOmniBrowser'; load. ((Smalltalk at: #ConfigurationOfOmniBrowser) project version: #stable) load. "The symbolic version #stable is not defined in ConfigurationOfOmniBrowser for the current platform." (Smalltalk at: #ConfigurationOfOmniBrowser) project latestVersion load "MessageNotUnderstood: Preferences class>>enable:" Cheers, Hernán
