For the past many years, Array Web Development (formerly Marketing Portland) has specialized in building web sites using the Joomla platform as the framework and CMS aspect of nearly all sites developed. On top of that, we quickly gravitated to the (arguably) most popular design platform used atop Joomla web sites -- Gantry. Until Gantry 4 ("G4" herein), Gantry was basically a continually evolving design platform.
Gantry 5 ("G5" herein), however, represents a new direction. As of the launch of G5, the Gantry platform became more or less two distinct platforms. G4, as far as I can tell via various RocketTheme blogs and mentions, will remain supported by RocketTheme, and perhaps even developed further. I sense they may well kind-of wish they could leave it behind and just go on with G5 solely. But, as G4 powers such a massive number of web sites, they likely continue with it for a good long time.
We're still building out new web sites using G4, as it's still a superb, incredibly stable platform. But, as RocketTheme has devoted its theming efforts exclusively to G5-based themes (with a fine assortment of attractive G5 themes available as of this writing and scores of G4 ones), it's only natural that clients are beginning to gravitate more toward these newer themes as desired starting points for their web sites.
What I'd like to do is offer a run-down (fairly brief) of many of the more exciting features of G5, with various commentary suitable for users and developers alike. I'll try to include some commentary about how any of this differs from G4.
