For these issues apply the following strategy: - the latest stable version should load in 2.0 (1.4 is dead) - the latest dev version should most probably work in 3.0 So in this case, OSProcess could be easily updated to use 'Smalltalk os' since that exists already in 2.0, and nobody should even care developing or backporting software for 2.0.

what we could do is to not deprecate now the methods?

Suggestion about Spec

by Erwan Douaille

Hi, I'm working on the UIPainter importer. I'm able to import already existing spec windows but now i need to retrieve widgets properties. For example, on a ButtonModel i would like to retrieve the Icon. Actually if i want to retrieve it it means than i have to send #iconHolder message. The thing is, to set it we used #icon: Why not uniformize it ? For me, #iconHolder should be #icon. It will be more easier for me to retrieve informations, and for users to use it. -- Best regards, Douaille Erwan <douaille.erwan(a)gmail.com>
