I've just posted r41Alpha3 to the "MagmaTester" project of SqueakSource.
Most notable is the inclusion of sig's MaDictionary redesign. Thanks Igor! The test cases pass with them but I haven't done anything more at this point. Proceed with caution, just in case.
Also included is a good bug fix for renaming classes. Magma was being notified of the rename, but needed to rehash two of its internal Dictionary's to ensure subsequent access is correct.
There are other minor improvements.
