Lifecycle Timeline
2Description
OpenProject is an open-source, web-based project management software. Prior to 17.0.2, the drag&drop handler moving an agenda item to a different section was not properly checking if the target meeting section is part of the same meeting (or is the backlog, in case of recurring meetings).
