I'm still figuring out how to use Dolphin 4 and still have the ability
to revert to version 3 if something (more) goes wrong. To that end I
have tried saving packages from Dolphin 4 in Dolphin 3 format. Using
the package browser, I select my test package, right click, chose save
as..., select the Dolphin 3 package format, and save the .pac file.
When this file is installed into Dolphin 3, Dolphin complains
before/after/during converting package from version 6 to: 5.

If this problem were solved, the next would have to do with the code
that comes next in the .pac file:
Object subclass: #HeatConduction
instanceVariableNames: ''
classVariableNames: ''
poolDictionaries: ''
classInstanceVariableNames: ''
I don't think that Dolphin 3 will understand this with
classInstanceVariableNames, will it? This makes me wonder if the file
is really being written in version 3 format. Am I doing something
wrong?
