Comment #4 on issue 3445 by torsten....@astares.de: [Repackage] "SUnit" should be well structured
http://code.google.com/p/pharo/issues/detail?id=3445
There is nothing in the changeset that should make 1.2 unstable.However - if you want we can defer it to 1.3. The help package is in work anyway.
The failing SUnit tests are fixed BTW (see http://code.google.com/p/pharo/issues/detail?id=3415)
