To save you time on creating sprint, now sprint date are selected by default depending on the current date and the dates of the stage they are created in.

So if a sprint is not associated to a stage, it will be created by default from the current date and will last 2 weeks by default. Of course, you can change it if you need, either with the form or graphically on the roadmap.

If a sprint is associated to a stage, it will create by default inside the stage date range and after the existing sprints in the same stage. So if you do sprint after sprint, you do no need any more to manually arrange the date so that the sprint are just following each other !
