Intent to Change License for Squeak 4.0

The Squeak Oversight Board plans to finalize the multi-year effort of re-licensing Squeak. Squeak 4.0 is scheduled to be released on Monday, March 15th, 2010 and will be licensed under the MIT License with some original parts remaining under the Apache License. This release will be functionally equivalent to the previous 3.10.2 release. Current development work will be released as 4.1 as soon as possible following the release of 4.0.

This notice is intended as a "last call" before the actual license change takes effect. We have assembled re-licensing agreements from
every identifiable contributor. However, if you have contributed to Squeak or know of someone who has contributed and has not been contacted about the re-licensing effort, this notice is intended to make you aware of the upcoming change and to allow you to contact the Squeak Oversight Board regarding your contributions before the license change takes place.

Please distribute this notice widely. Questions or comments should be sent to relicensing@squeak.org.

Squeak

Welcome to the World of Squeak!

Squeak is a modern, open source, full-featured implementation of the powerful Smalltalk programming language and environment. Squeak is highly-portable - even its virtual machine is written entirely in Smalltalk making it easy to debug, analyze, and change. Squeak is the vehicle for a wide range of projects from multimedia applications, educational platforms to commercial web application development.

Noteworthy uses of Squeak

• Children's Machine - The One Laptop Per Child (OLPC) initiative leverages Squeak to power the Etoys application shipped with every laptop around the world.

• Etoys is a powerful script-based environment to learn science and math by encouraging exploration and experimentation.

• Pharo is a Squeak fork that focuses on web application development. The Seaside development team does its development work on Pharo. 

• Seaside and Aida/Web are two web frameworks for developing complex dynamic web applications which by leveraging the Smalltalk strengths considerably ease the web application development.

• Croquet is an open source software platform for creating deeply collaborative 3D multi-user online applications. It features a network architecture that supports communication, collaboration, resource sharing, and synchronous computation among multiple users.

• Sophie is a digital media assembly tool to combine images, text, video, and audio into a single multimedia document such as slideshows, presentations and annotated videos.

• Scratch is a new programmable toolkit that enables kids to create their own games, animated stories, and interactive art -- and share their creations with one another over the Net. Scratch builds on the tradition of Logo and LEGO/Logo, but takes advantage of new computational ideas to make it easier to get started with programming (lowering the floor) and extend the range of what kids can create and learn (raising the ceiling).
