Cool - congratulations Chris!


> I am pleased to announce version 1.5 of Magma for Squeak 5, now
> available on SqueakMap.  Magma allows multiple Squeak images to
> collaborate on a single, large object model, with the robustness and
> control expected from a database.  It offers the most transparent db
> access possible for Smalltalk, affording the user the ability to
> develop complex, performant designs, iteratively, on-the-fly.
> It has been designed for "continuous flow" development, the way
> Smalltalkers like and expect to work.  For example, I could have
> connections open to 3 separate databases, open transactions in any of
> them, and having restructured a class hierarchy in the model, and
> stepping through the debugger when that "final boarding call" for my
> flight is announced.
> Thanks to the image, this scenario has never been a problem for
> Smalltalkers and Magma is deliberate to ensure this flow is
> maintained.  Once at 10K feet, I can resume stepping through that same
> debugger within 5 seconds of restarting the image, DB connections
> intact, commit my transactions when I'm ready, done.  Magma handles
> every aspect of that use-case correctly even in multi-user
> environments, and has so many safety and integrity features, it is the
> safest way to develop and keep a model in Squeak.
> This release coincides with the release of Squeak 5, and has many
> improvements and fixes over Magma 1.4.  Detailed notes about these
> improvements are available at http://wiki.squeak.org/squeak/6209.
>  - Chris
