Squeak 4.1 released 23 April, 2010

Squeak 4.1 has now been released! This version combines the licence change occurring in the 4.0 release with the development work that has been going on while the re-licensing process took place.

Much of the work in this release has been focused on fundamental improvements. Major achievements are the integration of Cog’s closure implementation, the improved UI look and feel, the new anti-aliased fonts, the core library improvements, and the modularity advances.

One key focus for this release was to address the issues that have been known to frustrate developers using Squeak for the first time. A much improved set of UI widgets, the new menu bar including the fast search control, integrated help, improved test coverage, more class and method comments, and integrated syntax highlighting all make the system more accessible. The new full closures, the new traits implementation, multiple improvements to the collections and streams classes, the new NumberParser hierarchy all help make development easier and produce cleaner, faster code. Deploying your completed applications will be made easier by the work done on making many modules unloadable, and by support for other cleanup activities.
