When using Joomla 1.6 upwards, the component can now be upgraded by just installing the new copy. No more need copy files via FTP for an upgrade.
A brand new comments system has been added to Freestyle Support.
FAQs, KB Articles and Announcements can now be edited on the website frontend. You can either specify per user permissions for this or use Joomlas built in permissions.
You can now have nested categories in the knowledge base. Freestyle Support also now support articles without a category.
The testimonials component has been completely rewritten with many new features.
Several improvements have been made to the support ticket system on the user site. The process of replying to a ticket has been streamlined to be more efficient, and the ticket information can be displayed in multiple columns along with several other changes.
Users can now also have global custom fields that are shared over all that users tickets. This can be used to note information for a user that can be displayed with all their tickets.
A new set of features have been created to allow groups of users to share tickets on a support portal. Each group has several permission options to allow the users to view, reply or close the tickets of other members. Group administrators can add new users in the group, and change the permissions of the existing members. Shared tickets can be set to email all users that the ticket is visible to when emails are send.
Tickets can also now have other users added to them on a per ticket basis. This allows a user to add in other users on a specific ticket.
There are also many other smaller additions and bug fixes in this release (too many to list)
