Hi folks. I think we need to improve the changes/changelog between Pharo versions: 1.0, 1.1 etc. In addition, we need to document somewhere, how external packages maitainers should update their code. Sometimes, with a deprecated it is easy as you can say which other message to use instead. However, removing TheWorldMenu, FillInTheBlank, Preferences, etc it is more complicated as you cannot deprecated. So...if we want maintainers of external packages to update their versions to work with Pharo 1.1 we should document and explain what to do for these situations. For example, I have NO IDEA what to do with code that has references to those classes. Seriously, I don't have idea how to fix them. I propose something like Seaside at least: http://www.seaside.st/documentation/migration/28to30 Maybe the best start point is: http://code.google.com/p/pharo/wiki/ActionsInPharoOneDotOne Sorry I cannot help by myself with this. I am just speaking in case someone can know and can spent few hours and help with this. Cheers Mariano
