We have had a busy few weeks here on our latest Mermaid sprint and are pleased that this release brings some new features for you to use, as previewed in our recent blog posts.
New Features and Improvements
MM-1497 ‘Occasional Tasks and Groups’ Allow tasks and groups to be active only for certain repeat numbers of their parents.
For a comprehensive breakdown of this new functionality and the ways in which it may help you model your operation please read Ben’s recent series :-

MM-1513 ‘Show all repeats on Gantt Chart’
To complement the ‘Occasional Tasks and Groups’ above we have also added functionality to the gantt chart so that you can now toggle on and off the showing of repeats with your tasks. This will help you to visualise exactly how the repeats and their transits are modelled in Mermaid. You can toggle repeats on and off in the gantt chart with the following circle button to the right of the screen. 
MM-1218 ‘Associate MER and MRES files with Mermaid’
.MER and .MRES files can now be double clicked in Windows Explorer to open in Mermaid.
