And you want that. Especially when a new release comes out with for

Yes, but that only solves it for .sar files not DVS .st files.

I don't think so - I think I have covered all bases on that.

I did find out the problem about installedPackages (installing SqueakMap
Base twice messed it up, bad postscript) and have now also written a
slick
scan-the-changelog-for-installation-notes-to-rebuild-the-dictionary-with
-proper-sequence-numbers-method. :-)

It seems to work but I haven't activated that method call anywhere yet.
Check class side of SMSqueakMap.

PS. If sequence numbers pop up counting from -9999 and upwards that is
because of either:
a) The scan found old installation notes without stamp/number. Starts
those from -10000 to ensure correct ordering.
b) Postscripts still use the old noteInstalledPackage:version: call
which will have the same effect because that is in fact the method being
logged in the ChangeLog.

regards, Göran

PS. Daniel - if you are reading this: Take a look at the method
mentioned above SMSqueakMap class>>recreateYaddaYadda... It should
produce a proper sequence for your load scripts.
