On the User Interface (UI) side there have been many fixes and enhancements for overall better visual consistency, improvements to Toolbars and Wizards, and, enhanced documentation. Feature related improvements were made to Searching, Trackers and the powerful Plugin List Execute among many others.
Perhaps the most significant are the fixes to HP5 to "Create, share and reuse interactive HTML5 content in your browser". This valuable feature in Tiki 19.1 is only available on a handful of Content Management Systems (CMS) today, ensuring Tiki's leadership role in the segment.
