We have been focused lately on increasing the performance of large flows. We have decreased the time it takes to start a large flow by about 10 times. We have also brought the same level of improvements to updating the the status of a task or a workflow. We added support for marking tasks as 'milestone' tasks. You can view workflows using a new milestone view so you can gauge a flows progress based on it key tasks. We also made some user interface changes to the designer to make it easier to work with complex workflows. Lastly we updated the Dashboard view to make it easier to sort your tasks. We are also able to show more task details at a glance in the new format. There are tons of other little improvements.
