About 4 moons have passed and Amber - the Smalltalk for the web - has

libraries! It's a *real* Smalltalk, the environment is all there 
including Workspace, Transcript, Browser, 
senders/implementors/references to class, TestRunner, Inspectors, code

don't want to write applications in it. Smalltalk is immensely cleaner, 
both syntactically and semantically with a simple class model and a 
lightweight syntax for closures. It is in many ways a perfect match for 
the Good Parts of JavaScript.

And having a true live interactive incremental development environment 
where you can build your application directly in the browser is 

Below follows a summary of the major changes since release 0.9. We hope
