Pyjamas provides a python-to-javascript Compiler and a Web Widget set, the combination of which allows developers to easily write well-designed desktop-like Rich Media Applications in python classes and modules that will execute in all major web browsers. without having to write a single line of javascript. Pyjamas is a port of Google Web Toolkit.

Version 0.1 proved the concept and showed Google's own examples working in a well-behaved browser.

Version 0.2 fixes numerous issues that arose as people started to use pyjamas for their own applications.

Version 0.3 is now considered a Stable / Production release, and adds support for IE7.

Version 0.4 is now considered a Stable / Production release, fixes an IE7 user-agent string change, adds a few widgets, some more python language features, and bug-fixes.

Version 0.5 is a restructuring of the compiler output, enhancement of the language support, adds run-time stack traces, dynamic module loading and much more.

Version 0.6 brings over 140 enhancements to Pyjamas (see CHANGELOG). The compiler has had a major rework to bring python-like features (such as multiple inheritance, superclasses and more); Pyjamas-Desktop has been merged into the standard distribution, and has had support for both XULRunner (stable) and MSHTML (experimental) added, as well as the first port - PyWebkitGTK (useable: no 2D SVG Canvas support).

A Note to American Readers

"pyjamas" is actually the British spelling of what you would spell "pajamas". In other words, it's not a clever misspelling of a word, it's an even cleverer use of a real word. For this reason, it should not be pronounced PIEjamas. Just say it like you would "pajamas".
