In order to serve the broadest needs, there are several downloads here to choose from.
The Unified installers are the ‘kitchen sink included’ packages. These are Disk Images that contain everything. The server installer, the preferene pane, the client tools, the developer tools and any of the documentation bits we have created. Because they include everything, they are also the largest, with the current .dmg files weighing in at a svelte 180mb.
At this point, only the Unified Download is available during our transition to the new site layout, and hosting. The rest of the downloads will be coming as we complete our migration.
