we try to release updates every 2 months or more often. Sometimes we have periods when we fail to follow the schedule. It's related with the support of several private projects or with releasing the new components. For instance now, we want to be in time to the end of the year to release two new products - QtitanDocking
(similar to the docking of VisualStudio) and QtitanNavigation (Microsoft Dynamic CRM like menu navigation).
