3.5 release
3.5 was released in April 2003. This was just a quick re-release of 3.4, with a couple of important bugfixes included. (A ClassBuilder fix which allows all classes to be recompiled, and a fix for loading projects with jpegs.)
3.4 release
Released on March 3rd, 2003, by Doug Way taking over from Scott Wallace.
The main purpose of this release was to create an up to date, viable version, which would be a good starting point to making Squeak more modular and it's development more decentralized.
Changes:
Includes non-modules related updates from 3.3a, including the dynamic filelist services refactoring.
An option to load the SqueakMap package catalog and the base Package Loader from the net.
A dynamic open menu so packages can now register there and become first class applications.
Refactorings making various parts of the image easily removable.
