I am pleased to announce a new release of Magma. Release 42 brings unprecedented scale and availability of persistent domain models to Squeak users. In particular, a single logical repository can now be served from multiple servers simultaneously, each hosting their own physical copy. To maintain consistency, just one server receives writes and broacasts commit-records to "warm-backup" servers asynchronously. The warm-backups ensure to keep themselves constantly up to date automatically.
Individual servers in the "Node", even the primary, can be brought off-line and back on-line without disruption to clients. Maintenance routines such as full-backup and compression may optionally be run while a repository is off-line, resulting in true 24x7 operation with no performance degradation due to maintenance jobs. The more physical copies of a repository that are brought on-line, the more read-scale the overall Node will provide. For more details, see:
http://wiki.squeak.org/squeak/6101
Scales up as well as down: Magma retains it's existing ability to scale an existing, large, multi-user repository _down_ to a single user on a single laptop easily, without a single change to application code. This can be very useful for diagnosing production issues without disturbing production.
42 one-click loads cleanly into 3.9, 3.10 and Pharo, and is supported on those images.
For now, the Magma home page still resides at:

Can I ask something?
You have a mcm for the complete magma tester set, r42final.
I'm loading magma with a script, using installer. The installer can load mcm files and load each package on the mcm. But if I use the mcm for r42final I get everything. Could you also add mcm for the other sets, that is, the client set and the server set of magma packages. Maybe something like:
r42-MagmaTester. r42-MagmaServer. r42-MagmaClient.
This will permit to load, using magma configurations, only the magma packages needed. Actually I use:
"Magma server" Installer ss project: 'MagmaPharo'; install: 'Ma exception handling'; install: 'Ma base additions'; install: 'Ma proxy support'; install: 'Ma traverse object graphs'; install: 'MaFixedWidthReport'; install: 'Ma Statistics'; install: 'Ma object serialization'; install: 'Collections-BTree'; install: 'Ma special collections'; install: 'Ma client server'; install: 'WriteBarrier'; install: 'Magma client'; install: 'Ma contextual search'; install: 'Magma server'.
to get the magma server only. I compiled this list from the Magma Server SAR file.
Thanks
