Hi, when I load Metacello to the Pharo Kernel, I still use the SqueakSource repository and use ConfigurationOfMetacello. It is a relict from times when Metacello was not directly loaded in the standard image. We need to change to have the Metacello in the same version that is in Pharo. And we have several options: 1) load Metacello directly from Pharo30 repository on Smalltalkhub using Gofer 2) make ConfigurationOfMetacello part of Pharo and load it from Pharo30 repository on Smalltalkhub using its own configuration and Gofer 3) to have ConfiguratonOfMetacello in the Smalltalkhub repository but do not have it preloaded in the standard image What do you think? -- Pavel
