Hi all, I'm on vacations, so I've produced a new patch version of Iceberg :). This version restores compatibility with Pharo6, which was broken since latest changes done for Pharo7 64bit support. https://github.com/pharo-vcs/iceberg/releases/tag/v1.5.7 I hope people still using Pharo6 find this useful. You should be able now to use again the update script to use latest iceberg on it. I've updated the doc to point to the latest supported version: "load iceberg"Metacello new baseline: 'Iceberg'; repository: 'github://pharo-vcs/iceberg:v1.5.?'; onWarningLog; load. On this same direction, we have been discussing that v1.5.* will be the latest minor version supporting Pharo6. Still, we will keep integrating bugfixes and patches as they come. New versions (>= 1.6) will host the new features and will be available and maintained for both the stable Pharo7 and the in-development Pharo8 versions. Enjoy, Guille
