There will be an update to the code prior to JavaOne (May 5). We're calling it 0.5. Too much has been going on, mostly on the server side, to have done it sooner.
This updated version will point to new Solaris and Linux servers providing core imagery via WMS rather than the proprietary, single-platform, never ending maintenance headache tile server system we've suffered with. It will also point to an updated WFS server for placenames. The WMS server code is part of the release. (But it's very specific for WWJ needs, and not a general purpose solution like you'd get from GeoTools.) Both of these new servers use Squid for caching. We've also arranged for very high performance mirrored hosting, which will go on line in late May.
When we release 1.0 we expect to place it in a public subversion system.
Thanks for your patience. Non uno die roma aedificata est.
