A number of other open source CMS have moved to a more rapid release cycle with LTS, but Tiki's all-in-one model has advantages compared with the extension-based model of other systems. In Tiki, all features are ready at the same time while with other extension-based systems, it is often the case that not all features are ready at the same time, and too often, extensions are never ported to the next version. Thanks to the Tiki model, we have inherent synchronized releases and easy upgrades. See: http://pluginproblems.com/
