Comment #1 on issue 3189 by guillermopolito: Changes not working since update 12220 http://code.google.com/p/pharo/issues/detail?id=3189 With the last version of PharoCore 1.2 (12233) I did ScriptLoader new cleanUpForRelease the I created a new class and it got logged in the change sorter... So I couldn't reproduce it.
