I'm happy to announce that Magma now supports Dictionary's, Set's and Intervals being used with the WriteBarrier. This should provide most applications a significant boost in performance.

Currently it is included in the most-recent code, which can be installed via:

Installer new merge: #maInstaller. (Smalltalk classNamed: #MaInstaller) new merge: #magmaServer

The (head) script on SqueakMap will give you as much, plus Magma's test suite.

Cheers! Chris
